Special feature of 1905 film network Salt lake, blue sky, white teenager, white skirt girl; It’s so clean in the warm sun, between heaven and earth … …After watching the movie, this scene must be lingering. This beautiful ideal is an illusion that Wei Yihang (Jackson Yee), a teenager, can only see before he falls sick and faints.

A smelly-faced teenager in front of a stranger is a cold-faced teenager in the eyes of his family. The taciturn and perverse "juvenile rage" is vividly reflected in the adolescent boy Wei Yihang.

Under the extreme conditions of brain cancer, all this rebellion is nothing more than a hard shell for him to choose to "confront" or escape from his own misfortune and strange eyes around him. The first half of A Little Red Flower focuses on the ice-breaking process of this layer of defense.

As a key figure who lights up Wei Yihang’s gloomy life on the plot line, Ma Xiaoyuan (played by Liu Haocun), an optimistic girl, changes everything with love. As a "senior" brain cancer patient, her weapon to break the ice is not only initiative, but also empathy beyond simple communication.

Han Yan, a director with shooting experience, once again returned to the "normal" life perspective after throwing out the protagonist’s illness dilemma. Compared with "tumor jun" who had to be confined to the ward scene most of the time, "Little Red Flower", which made many viewers call "watching a youth film", obviously went further on the positive road to sadness.

However, no matter how beautiful the picture of youth love is, its basic starting point still cannot escape the awe of life.

The opportunity for them to really get to know each other is the conflict and opposition between them on whether their cancer patients need chicken soup for the soul; Several degrees of ambiguous clutch are closely related to the recurrence of their illness.

As a highlight of the film’s plot and post-publicity, the Weibo accounts of the two protagonists have become the key clue for fans to resume the film.

The homophonic interpretation of Wei Yihang’s "WEIYI’s voyage" reflects the firm but helpless yearning of the boy with cancer to travel to distant places. The screen name of "how far to roll" is extremely suitable for Ma Xiaoyuan’s jumping personality, and at the same time, it more intuitively reflects her drive for Wei Yihang’s courage to dream.

Although their journey together failed to go far, this journey of spiritual companionship with Xiaoyuan still stirred Yihang’s heart after her death. With this growth, Yihang ordered a beef rice takeaway for her haggard father in the name of a dead girl with cancer. After knowing the secret of the lover of Wu Xiaomei (Yun-peng Yue), the owner of the cancer patient group, she chose to support silently, which really realized the difficulty for her parents to spend everything to save themselves … …

The first little red flower in the film of the first voyage that passed on the spirit of "Little Red Flower" is Xiaoyuan’s reward for his "initiative for the first time in life". If the two people’s similar illness backgrounds and family status are reflected, you will find that the process of actively pursuing a small distance under the encouragement of the other party can also be regarded as a journey of self-discovery — — The so-called proactive process is actually the acceptance of all the states such as one’s illness and dreams, unbearable and great.

Years later, Wei Yihang, who has finally completed this "only" voyage on the Qinghai Lake, which is highly corresponding to the image of the dreamland in reality, saw the face of his eternal lover and found a little red flower belonging to life and hope in the "migration of 100 million sheep".

This little red flower has actually been in the heart of Yihang. With this performance, Jackson Yee undoubtedly won a "little red flower" for his fresh but wonderful actor resume.

Different from Li Xiaobei’s guardian-like depth and courage, it seems that he only needs to return to the corner of Wei Yihang, who is a teenager, but he tests the emotional transformation of actors in multiple dimensions such as illness, autism, love and release.

That scene’s confession to Xiaoyuan after drinking is not only a self-doubt and frustrated teenager who can’t help himself after getting drunk, but also an accusation of unfair fate after being substituted into the status of a cancer patient.

"I’m afraid I’ll die as soon as I take out my heart." In addition to talent, such difficult movements are naturally voiced, and Jackson Yee’s belief in performance deserves greater praise.

Also worthy of being awarded the "Little Red Flower" are Liu Haocun, who has performed more and more, and the parents who have made intensive contributions to tears. Under the joint efforts of each audience’s unique interpretation, this "little red flower" has gradually become the public’s vision mapping.

Perhaps, you and I, who can feel the red flower in our hearts, will find the lake in our dreams in 2021.

The data shows that in September 2024, Geely Automobile’s new energy sales reached 91,000 vehicles, accounting for more than 45% of Geely’s total sales, and the development momentum is quite strong.

But do you know which car sold the most in September? It’s not a new energy vehicle, but Geely Xingyue L. It seems that the vitality of this fuel vehicle is still very strong, which is worthy of Geely’s good maintenance. Recently, the 2025 Geely Xingyue L Dongfang Yao SUV was launched, and five models were launched, with an official guide price of 147,700. So, is this new car worth starting with?

What kind of car is the new Xingyue L?

The new Xingyue L is named after Dongfang Obsidian, which sounds novel. It is actually a high-end version of the current Xingyue L. So what changes have been made to this car?

In terms of appearance, Xingyue L has basically not changed, and still adopts the family-style design style, retaining the straight waterfall net that has been used for many years. In the domestic fuel auto market, there are not many models that can control this design technique, and the Star Yue L is one of them.

The body size of the new car has not changed. The body length is 4770mm, and the wheelbase is 2845 mm. It adopts the big five-seat design and has a good performance in space, which can meet the daily needs of family users.

Compared with the current model, the new car has been upgraded in the seat function, adding the massage function of the main driving seat and the headrest speaker, and also adding the electric adjustment function of the second row seat, which is rare in the same price model.

In terms of interior, the new car has been adjusted to some extent. This car is still equipped with dual 12.3-inch large screens and a 12.3-inch full LCD instrument panel, but the size of the gear handle has been greatly reduced, which seems to have a stronger sense of design. At the same time, crystal material has been added to enhance the sense of grade of the entire cockpit.

At the same time, the new car also adds the color matching of Shaohua apricot, which looks more attractive and more suitable for high-end users. This fine-tuning range is not large, but the improvement of product strength is still obvious.

In terms of intelligent layout, the new car also has a good performance. It is equipped with Galaxy OS 2.0 intelligent lathe system and Qualcomm Snapdragon 8155 chip, and the physical buttons on the central control panel are cancelled, which looks more scientific and technological. In addition, the new car comes standard with a 25.6-inch AR-HUD head-up display system, which can display all kinds of information related to the vehicle intuitively.

The new Xingyue L is still a fuel car, but its performance in intelligence is beyond the scope of ordinary fuel cars. In terms of intelligent driving, the new car provides L2-level driving assistance functions such as active braking, lane departure warning, transparent chassis, reversing side warning, lane merging assistance, lane keeping assistance system, road traffic sign recognition, etc. Even for new energy vehicles with the same price, many of them can’t reach the level of Star Crossing L..

At the same time, the new car also provides a high-level intelligent speech recognition system, which can realize the voice awakening of four sound zones, and at the same time, it can download various commonly used APPs through the app store to further enhance the user’s car experience. It’s hard to believe that this is a fuel car if you only look at it from the aspect of intelligence.

How is the power system performing?

So far, the penetration rate of new energy vehicles in China has approached 60%, and fuel engines have become "backward" products within a few years. However, judging from the strong performance of Xingyue L, many consumers still like fuel engines.

The new Xingyue L launched this time is equipped with a 2.0T turbocharged engine and matched with an 8AT gearbox. The maximum power reaches 175kW and the maximum torque reaches 350N·m, which has a certain gap compared with the new energy vehicles at the same price, but it is still relatively competitive in fuel vehicles. However, it should be noted that this engine originally came from Volvo, so it needs to add 95 # gasoline like a luxury car, which increases the cost of using the car.

Compared with the current models, the new car has also been upgraded in the power system.

First of all, the new car provides a timely four-wheel drive system and multiple clutches, which brings strong off-road capability. In the process of go on road trip and Zhou Bianyou, if users encounter some bumpy and slippery roads, the four-wheel drive system can ensure the stability of the car body and improve the riding experience.

In addition, the new car also provides a suspension soft and hard adjustment function, which can adjust the suspension according to the change of road conditions, bringing users a driving experience beyond the same price of fuel vehicles. Compared with Geely’s new energy vehicles with adaptive suspension, the suspension of the new Xingyue L is not easy to get. After all, it is a fuel vehicle, and it is unlikely to reach the level of new energy vehicles in terms of intelligence. However, since users choose this car, they will compare it with the fuel car with the same price, so that the advantages of Xingyue L in suspension will be revealed.

What is the prospect of the new Xingyue L?

In fact, the product idea of the new Xingyue L is very simple. It continues to be equipped with a fuel engine, and at the same time, some rare configurations on fuel vehicles have been transplanted from new energy vehicles, such as AR-HUD, L2 driver assistance, intelligent vehicle system and so on.

The intention of doing this is obvious. Many consumers don’t like the endurance anxiety of new energy vehicles, but they also want the performance of new energy vehicles in intelligence. Xingyue L is equivalent to a transitional product between fuel vehicles and new energy vehicles. In a relatively low price range, it tries to provide a car experience comparable to new energy vehicles as a fuel vehicle, while avoiding the problem of endurance anxiety.

This is a more rational approach, and it also captures the actual needs of many users. New energy is indeed the future development direction, but the needs of consumers are diversified, and they will only choose the models they really need. The "intermediate product" of Xingyue L will disappear one day, but before it disappears, it can still bring a large number of users to Geely.

Summary: Xingyue L is one of Geely’s most successful models in recent years, so it is necessary to carry out intelligent transformation. It is still a fuel vehicle, not an oil-to-electricity vehicle, but in terms of product strength, it has surpassed some nondescript oil-to-electricity vehicles and is more attractive to consumers. So, if you have a car purchase budget of hundreds of thousands, will you choose this car?

What are the most noteworthy models at the end of the year? The newly listed Geely Galaxy Starship 7 EM-i should be ranked first. The new car is priced at 103,800-136,800 yuan, and there is a limited-time discount of 4,000 yuan. The price is only 99,800 yuan. So will this new car of Geely Galaxy work?

[car home Shangluo Preferential Promotion Channel] Recently, Geely Automobile’s hot-selling models ushered in a new round of preferential promotion activities in Shangluo area, with the highest preferential margin reaching 7,000 yuan and the lowest starting price of only 103,700 yuan.

The steering wheel is wrapped in leather, which supports manual adjustment up and down and back and forth, making it comfortable and ergonomic. In terms of seats, the car is made of imitation leather. The main driver’s seat has front and rear adjustment, backrest adjustment and height adjustment (2-way), while the co-pilot’s seat provides front and rear adjustment and backrest adjustment functions, with good comfort and support. In addition, the car is equipped with two USB interfaces in the front row and a USB/Type-C interface in the back row, which is convenient for passengers to charge electronic equipment.

Xingrui is equipped with a 1.5T 181 horsepower L4 engine with a maximum power of 133kW and a maximum torque of 290N·m, which is matched with a 7-speed wet dual-clutch gearbox and has excellent power performance.

The owner of car home said: "I really don’t like the kind of car that looks too exaggerated, so I was more interested in Xingrui at that time and took a fancy to its appearance on a large scale. The appearance of this car gives people a feeling of calmness. Of course, the large vertical net at the front of the car is also very imposing."

　　CCTV News:Shield machine is the heavy weapon of the country, and now it is being used in more and more projects. Because the shield machine is driving underground, the shield driver can’t see the direction and needs to rely on the data of the surveyor to operate, which requires very high measurement accuracy. And surveyors can’t see the underground situation, so shield survey is also called the most difficult survey work.

　　During this "May 1" holiday, the first domestic 16-meter super-large diameter slurry balance shield machine "Jinghua" was running 24 hours a day in the 50-meter underground west line tunnel of Beijing East Sixth Ring Road Reconstruction Project, striving for high-precision penetration of the tunnel this year. It was escorted by the survey team led by Li Weichuan of China Railway 14th Bureau.

　　Don’t look at leading the team to get used to it now. When I just graduated, Li Weichuan failed to adapt to the hard work for a while.

　　Despite the difficult conditions, Li Weichuan chose to stick to it when he saw that shield machines were still rare in China at that time and there were very few professionals engaged in shield surveying. He began to constantly learn surveying knowledge from the masters, and rechecked the excavation data and geological conditions over and over again.

　　After many projects, Li Weichuan gradually became the person in charge of surveying. I thought my measurement technology was already very proficient, but in the process of debugging the guiding system of an imported shield machine, Li Weichuan suddenly felt the gap.

　　In order to fight for breath, Li Weichuan made extraordinary efforts. In addition to surveying, he began to actively learn the knowledge of various types of work related to shield machines, and constantly summarized the problems and solutions encountered in practical work. Hard work pays off. In 2014, Li Weichuan successfully obtained the third-level (advanced) certificate of engineering surveyor. In 2021, it also passed the highest professional qualification in the construction industry — — The first-class registered construction engineer examination has completed the transformation from technical personnel to highly skilled personnel.

　　In the past ten years, he has participated in the engineering survey tasks of many important and difficult projects, such as the diversion tunnel of South-to-North Water Transfer Project, the Slender West Lake Tunnel in Yangzhou and the Beijing-Tangshan High-speed Railway.

　　Li Weichuan, Project Survey Director of Beijing Sub-center of China Railway 14th Bureau:Our domestic shield machines are becoming more and more advanced, and now many shield machines have been exported abroad. I think that one day, if their problems can’t be solved, they can consult us in the past. At that time, we will not hide, and we will share some experience and knowledge with them.

　　 On the afternoon of September 19th, National Cyber Security Publicity Week held the first forum "Cyber Security Technology Summit Forum". The world’s top cyber security experts, such as Eugene Kaspersky, CEO of Kaspersky, Steve Martino, Chief Information Security Officer of Cisco, Shen Xiangyang, global executive vice president of Microsoft, Zhang Yong, CEO of Alibaba and Zhou Hongyi, chairman of 360 Company, expressed their opinions and shared their thoughts and suggestions on cyber security technology.

　　 As the main forum of the National Cyber Security Publicity Week, the "Cyber Security Technology Summit Forum" is guided by the Central Network Information Office, hosted by the Wuhan Municipal People’s Government, and undertaken by China Internet Network Information Center, China Cyberspace Security Association, and Electronics No.1 Institute of the Ministry of Industry and Information Technology.

　　 Yang Xueshan, former vice minister of the Ministry of Industry and Information Technology: The integration of the five major technologies will usher in an intelligent era within 15 years.

　　 Regarding the long-term development trend of information technology, Yang Xueshan takes 2030 as the boundary, and thinks that information technology will show four characteristics. At present, the transmission and processing technology is maturing, and the physical technology and physical limit supporting its development are coming. The application in various fields of economy and society has also reached or is touching the ceiling. In the visible time, there is generally no new technology to replace it. But maturity does not mean completion, and there are still innovations.

　　 Perception and behavior technology is in a period of rapid development. He believes that perceptual technology is the starting point and behavioral technology is the end point. How to make behavioral technology as mature as human brain commanding hands and feet, we still lack the support of theoretical basis. The content technology, that is, the familiar big data technology, is unevenly developed. Yang Xueshan introduced that the processing of digital data is mature, and it is entering a rapid development period for relatively simple digital data, text data and even some voice and video specific applications; The real audio and video processing can process digital, text, audio and video like a human brain. In this respect, we are still in the initial stage, which is the early stage of development. If the above five technologies are integrated to build a new system technology, it will become the most important content in the economic and social development in the next 15 years.

　　 Academician Tsinghua University Wu Jianping: Cyberspace security is actually the competition of high-level talents.

　　 Wu Jianping said that cyberspace is the fifth territory of mankind after land, sea, air and space. The challenge of cyberspace is mainly the challenge of Internet infrastructure security, which mainly includes the lack of source address, source address verification, large-scale network attacks, large-scale domain name hijacking and counterfeiting. Summarizing the characteristics of network security is that it is holistic rather than fragmented, dynamic rather than static, open rather than closed, relative rather than absolute, and global rather than independent.

　　 Cyberspace security is actually the competition of high-level talents. Before 2013, there were 96 colleges and universities involved in information security. Generally speaking, high-level talents are the most urgent. At present, about 60 universities in the world have master’s degrees in cyberspace security, focusing on chip security and Internet infrastructure security. Cyberspace security has penetrated into all parts of cyberspace. Strengthening basic research and mastering core technologies in cyberspace is the key to solve cyberspace security. We should cultivate more high-level talents such as masters and doctors.

　　 Zhang Yong, CEO of Alibaba Group: Prepare for the next vent.

　　 Zhang Yong said, from the beginning, safety has been our greatest concern. However, with the development of the whole information technology and the wide application of big data in life, network security cannot be prevented by defense alone, and the lasting vitality of security comes from attack. The most important thing is to be able to use big data and the technology we have mastered to trace and trace the upstream of the black and gray industrial chain. Only in this way can our industry and consumers be truly safe.

　　 The development of information technology is changing with each passing day. While many people are still discussing privacy protection and mobile security, in fact, various emerging technologies such as artificial intelligence, intelligent manufacturing, voice and image recognition are developing rapidly, and the security of the Internet of Things has become the next vent. Safety technology and protection must not be static. In this process, how can we predict the next tuyere in advance and prepare for the next tuyere is very important.

　　 Shen Xiangyang, global executive vice president of Microsoft: Trustworthy technology and security are the foundation when the fourth industrial revolution comes.

　　 Shen Xiangyang said that security and trust are becoming more and more important. With the development of information technology, we are welcoming the fourth industrial revolution, which will mainly focus on three types of technologies. The first type of technology is the development of the material field, including new materials, self-driving cars, robots, 3D printing, etc. The second category is the sustainable development of the biological field, in which technologies such as genetic testing and genetic engineering are not only helpful to human health but also to the development of agriculture and animal husbandry; The third category is the development of digital technology, which will affect everyone. Therefore, trustworthy technology and safety are the foundation for us to move towards the fourth industrial revolution. Shen Xiangyang said that in the past, we separated the physical space from the digital world, and now we know that the digital world is changing our physical life. In today’s world, there is no national security without network security. We not only live in a world of diversified technologies, but also live in an era when Internet security challenges. European governments have launched network security guidelines to protect infrastructure.

　　 Zhou Hongyi, Chairman of 360 Company: The accuracy of fraudulent SMS is improving. It is suggested to speed up the legislation of personal information protection.

　　 Zhou Hongyi said that some time ago, the media reported more news about the death of Shandong college students by phone fraud. Why is communication fraud so easy to succeed? On the surface, fraud is the result, but the reason behind it is the disclosure of personal information. Since the beginning of this year, many people feel that the accuracy of receiving fraudulent text messages has been greatly improved. In the past, fraudulent text messages were sent in groups. Now he knows your name and is easily deceived. At present, more and more websites have real data and information of users, but there are obvious loopholes in security protection. It is suggested that the state strengthen legislation in this regard.

　　 Steve Martino, Chief Information Security Officer of Cisco: There are five magic weapons to solve cyber threats.

　　 Regarding how to protect the network security of enterprises, Steve Martino said that there are five magic weapons to win. The first magic weapon is the need for an "architect". Enterprises need a comprehensive network security governance and operation system, and they need to look at their identity from a higher angle to start the most comprehensive protection. Everything is like a complete building, interlocking. The second magic weapon is education, and all employees will receive relevant education regularly, thus greatly reducing the bad influence brought by phishing websites. Thirdly, network security is as important as operational performance. We are very concerned about our performance, but we often regard network security as the second most important thing, which is wrong. With architects, we need a complete epidemic prevention system. Architects understand all the components and how they cooperate with each other. Security experts use the latest technology to stop threats, but if all departments do not communicate, the network crisis will not be solved quickly. Finally, a very adaptable and flexible defense system is needed.

　　 Ding Lieyun, academician of China Academy of Engineering and president of Huazhong University of Science and Technology: If information technology is not transformed, it will melt like a popsicle.

　　 Ding Lieyun said that in the past two decades, in the information field, the mode of transformation of university achievements has been continuously upgraded, and the related information security achievements formed by universities have made breakthroughs in a certain field. However, very few of them went it alone in the market, and most of them took the form of achievements transfer or shareholding, and the achievements could not get out of the ivory tower because they were "blocked" on the road of transformation.

　　 The original innovation ability is insufficient, and the poor connection between science and technology and economy has become a "blocking point". Ding Lieyun believes that the way to unblock traffic congestion lies in promoting the establishment of a collaborative innovation system integrating politics and Industry-University-Research. The government should build a platform and make overall plans for R&D activities. The country must have grand planning and overall design to comprehensively coordinate the research and development of important links in the information technology system, build an open technology ecology and create an effective means of technology ecology. At the same time, original innovation should be combined with integrated innovation. Enterprises should summon up courage to advance into the deep-water area of technology, no longer be limited to the innovation of information technology and security technology at the application level, aim at the national strategic needs, focus on the key breakthroughs at the infrastructure level, create a safe and independent information platform, and break through the technical barriers of multidisciplinary and multi-dimensional; Universities need multi-field technical cooperation breakthrough, and multi-disciplinary crossing is the inherent advantage of universities. To strengthen interdisciplinary crossing, we must have ideological innovation and institutional innovation at the same time, and speed up the last mile of improving the transformation of achievements; Although there are risks, there are more opportunities for breakthrough and decisive innovation. Finally, capital should have foresight to cooperate with innovation.

　　 Li Jiancheng, Academician of China Academy of Engineering and Vice President of Wuhan University: Network security construction is based on law and technology.

　　 Li Jiancheng said that Tsinghua University teachers were cheated, Song Zhenning’s case and other frauds in the media have hidden huge personal privacy leaks. However, "data openness" and "information security" are two sides of the same coin. In the era of big data drive, new resources, new thinking and new technologies have shaped new industries, spawned new occupations and created a new era. However, when big data is opened and data is released anytime and anywhere, it may also be attacked by hackers anytime and anywhere.

　　 So where does big data go under cyberspace security? Li Jiancheng suggested that law is the foundation, and management and technology are the support. Cyberspace security law needs to be promulgated urgently, and cyberspace security management rules and regulations need to be promulgated urgently. Law and technology are equally important in big data and information security. "

　　 Yang Debin, Director of the Office of the Chief Information Officer of the Hong Kong Government: Inform the network security information in time and defend against it early. Smart city products are designed with safety as the source.

　　 Yang Debin said that the penetration rate of broadband services and smart phones in Hong Kong has reached 84%. In terms of digital and personal safety, Hong Kong ranks fourth and sixth respectively in the world. At present, the types of threats to network security in Hong Kong include malicious software, advanced network attacks and denial of service attacks. In the future, the development of smart cities and the realization of smart transportation, smart medical care, smart power grid and smart home through the Internet of Things will not only bring convenience to life, but also aggravate the network security problem.

　　 Yang Debin shared several ways to improve network security: the first is to inform each other of network security information in time through people-to-people, government-to-government, and government-to-people, so as to prevent and resist some behaviors that affect network security as soon as possible. Second, enterprises need to take diversified protection work, not only a protective wall, or encryption, or backup, but also more knowledge and awareness training in employee training. In addition, in view of the new technology, all kinds of products developed in smart cities should take safety as the source of design. Different products must take all safety into account when designing, so as to achieve that all products can have methods to defend themselves from hackers and effectively resist them. In addition, it is necessary to strengthen the awareness of network security of netizens through seminars, publicity and schools.

　　 Jeremy Benn Flem, global vice president of Israeli Checkpoint Company: 4 The attack sounded the alarm and network security has risen to the national level.

　　 Remy Ben Flem mentioned that there are four typical cases of being attacked in the history of network security: one is Ukrainian power outage, which is caused by malicious code; Second, in the Central Bank of Bangladesh, attackers sent phishing emails to bank staff, stole terminal passwords, and transferred money between banks in the Philippines; Third, the arrival and departure stations of Hanoi and Ho Chi Minh City airports in Vietnam were attacked, which paralyzed the airports. Fourth, a chain hospital in Maryland was blackmailed and more than 1000 patients’ appointments were cancelled.

　　 Remy Benn Flem said that at present, physical safety can be well guarded, such as not letting anyone near our airport. But we should also see other factors, such as the instrument landing system. If you turn it off, the whole airport will be paralyzed, as well as the baggage system and ticketing system, which are vulnerable to attacks. Therefore, the future defense system will also be multi-layered. He believes that the current network security has risen to the national level. But to be one step ahead, the first thing is architecture, like an architect, to ensure its consistency; The second is defense, not only detection and discovery, but defense before the attack, which is very difficult; The third is automation, with an early warning system.

　　 Zeng Anye, President of Chow Tai Fook Group: To improve the national cyber security capability, it is necessary to get through all links and unite talents with each other.

　　 This year, Chow Tai Fook donated 300 million yuan to set up a cyber security fund. Under the guidance of the Central Network Information Office and the Ministry of Education, the fund is mainly used to reward outstanding cyber security talents, excellent teachers and excellent teaching materials, and support the training of cyber security talents. We believe that to enhance the national cyber security capability, we not only need the government’s strong support from education, scientific research and industry, but more importantly, we need to get talents from all links to unite with each other and build a complete cyber security ecological chain. In this process, we should pay special attention to giving full play to the role of enterprises and social capital and mobilize the enthusiasm of all parties. (China Netcom Su Ying)

Tesla is gradually losing the attention from consumers. From the product point of view, both Model Y, Model 3, Model S and Model X are old products many years ago, and it is difficult to stimulate consumers’ increasingly critical nerves.

Reuters previously said that Tesla had abandoned the production plan of Model 2, a low-priced electric vehicle with a price of 25,000 US dollars. Musk denied this and said that the unmanned taxi Robotaxi will be released on August 8 to fight back.

But in today’s consumption environment, cheap cars are the magic weapon to increase sales, and the significance of Model 2 is obviously greater than that of Robotaxi. Especially for Tesla, which is in the downward trend of sales.

From a macro policy point of view, the situation facing Tesla is even more difficult.In order to protect the interests of traditional car companies, the support for pure electric vehicles in the United States and Europe began to decline, and Europe was also erratic in the transformation of new energy.

In order to slow down the penetration of new energy vehicles in the world and gain more time for the local traditional automobile industry, some policy makers deliberately slowed down the progress of industrial transformation. However, Tesla, the core new energy automobile enterprise in Europe and America, was the most seriously injured.

Musk, who has been involved in the torrent of global economic and industrial games, has begun to face a fierce battle. His embarrassing role also determines that he must point out a new direction for the enterprise-Robotaxi unmanned taxi is the answer he gave.

After all, it can’t be rolled up

Reuters previously reported an exclusive news that Tesla had abandoned the production plan of Model 2, a low-priced electric vehicle with a price of 25,000 US dollars, because the China market was too big, which caused Tesla’s share price to plummet by more than 6%.

Musk, who has always disliked the media, also stood up and responded that "Reuters is lying". However, a few hours later, Musk suddenly announced that Tesla will release the driverless taxi Robotaxi on August 8.

Because Musk didn’t specify which part of Reuters’s content was "lying" and suddenly released Robotaxi unmanned taxi, it shows that Tesla’s cheap car project is very likely to be cut off or postponed.　

Reuters’s news is not groundless. Previously, several people familiar with the matter revealed to the media that Tesla cancelled the development of the entry model Model 2 and turned to the development of driverless taxi business on the car platform.

Providing consumers with affordable electric vehicles has always been the goal pursued by Musk. To this end, in recent years, Tesla took the lead in opening several rounds of price wars.

However, starting from this year, Tesla’s strategy of sinking the market through price reduction has become increasingly difficult to work. Even if Tesla’s $25,000 Model 2 is released, it is already difficult to form enough competitiveness-the price of BYD Qin Plus has dropped to 79,800 yuan this year, which is only $10,000.

The popular dream that Tesla always wanted to do, BYD realized it ahead of schedule. The low-cost model built by China automobile manufacturers through full-stack self-research and mature supplier system can make the product price drop continuously under the blessing of scale effect, so as to truly benefit the people and win the most sinking market.

Of course, the threat of China car companies to Tesla is not limited to low prices, but also poses a threat to Tesla’s Model 3 and Model Y in terms of cost performance.

In recent years, in the press conference of new energy brands in China, the words "the best within N" frequently appear. This clearly reflects a current situation:It’s really difficult to roll the cost performance of products in China, because you will meet more roll kings.. Xiaomi automobile confirms this point. At the beginning of development, SU7 was "sticking to the face" around Tesla Model 3, and the final starting price was 30,000 yuan cheaper than Model 3, which completely forced the palace.

What makes Musk feel uneasy most is probably the unique pricing method of China car companies.

Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, talked about the price of Zhijie S7. He once said that there was a heated debate within the company about the pricing of this model. At present, the prices of the four versions are all at a loss. We just want more consumers to experience Huawei’s products, and hope that the cost can be balanced with the quantity in the future.

I thought everyone came out to make money, but they just wanted to make friends with consumers. Lei Jun once said, "Every time Xiaomi sells a car, it is a loss. The first price of the top version is 350,000, which is also a loss. Finally, it is directly set at 299,900. Anyway, it is vomiting blood."

Of course, car companies are not vomiting blood in vain. Take BYD’s successful experience as an example. In the first three quarters of last year, when the bicycle price dropped by 17,000 yuan, the bicycle cost dropped by 21,000 yuan, the gross profit margin of the automobile business increased to 25.6%, and its earning power even surpassed Tesla.

To put it bluntly, selling cars at a loss is just a means, and its business model is to promote sales through price reduction, and then realize profit through scale effect. Of course, if you really can’t make a profit, it’s also good to "make friends" with consumers, and you can launch new products with lower positioning in the future to achieve profitability.

It’s just that it’s hard for Musk, and China car companies have given up all the roads he wants to take.

Become "Didi"

Musk’s obsession with Robotaxi was reflected long ago. It is mentioned in the Biography of Musk that his grand vision is to build a vehicle that can drive completely automatically without any human intervention.

In this way, Tesla owners can lie at home and let the car work outside to earn money. Users use software to summon Robotaxi like a car, but there will be no driver in the car.

The reason why Musk was able to shout out the release of Robotaxi on August 8 was due to the progress of FSD fully automatic driving.

At the end of March this year, Tesla launched the version of FSD V12.3, and the suffix cancelled Beta. Generally speaking, Beta stands for the Beta version, although Musk has previously explained that the beta suffix of FSD does not mean the beta version in the usual sense, but to reduce the blind trust of car owners. Now removing the FSD after Beta means that Tesla has become more confident in its autonomous driving technology.

FSD V12.3 has made great changes in the algorithm level, completely abandoning the previous methods that relied on manual coding rules and machine learning models, and instead fully adopting the end-to-end neural network AI system.

There are more than 300,000 lines of C++ codes written by engineers in the FSD V11 version control stack, but in the V12.3 version, there are no regular codes, only neural networks. Thanks to FSD’s powerful autonomous learning ability and more than 1 billion kilometers of driving data, FSD’s driving level is rapidly improving.

According to the test of American bloggers, the current version of FSD V12.3 has been able to achieve automatic driving in a variety of complex road conditions, including road conditions without drawing lines, cut-in sidewalks, red-light rails and other scenes.

Moreover, the driving experience of FSD V12.3 is very close to that of an old driver. For example, when passing by a road where there will be an intersection every short distance, FSD V12.3 will not let the vehicle mechanically move closer to the top speed, but choose a human comfortable speed.

This technology is not cheap. The price of FSD in North America is $15,000, and the optional price in China market has to exceed 60,000 yuan. However, Musk has long thought of a solution. According to his vision, the owner who joins the Robotaxi team can make a profit of 30,000 US dollars every year and become a wealth management product to help users repay their car loans. If the vehicle itself can help you make money, it seems that spending more money is nothing.

Despite this, there are still many doubts about whether Robotaxi can save Tesla’s short-term decline.

The vision of making vehicles a financial tool is beautiful. However, even if Tesla can successfully launch Robotaxi on August 8, it will take a certain period of test before it can be widely used.

Especially for driverless taxis, a traffic accident-whether the responsible party is the company’s car or not-will bring great trouble and even a devastating blow to the company in public opinion and law.

Previously, Cruise’s unmanned taxi had a traffic accident in San Francisco. After another car hit a pedestrian, Cruise’s unmanned taxi did not recognize someone under the car in front, and continued to run over people, causing the latter to be seriously injured. With the intervention of California and federal regulators, Cruise announced that all unmanned taxis would be completely shut down for technical safety risk assessment. After that, the Cruise business was shut down, layoffs were substantial, and the valuation was halved.

Tesla’s Robotaxi vision is beautiful enough, but it may also bring unpredictable risks to the enterprise itself.

Stay away from the trend

You know, Model 3 has been on the market for 7 years, and Model Y is already a model four years ago. Today, Tesla is in urgent need of a new explosion. However, the low-priced models can’t compete with China car companies, and the global market price is high and cold, and the prospect of Robotaxi is hard to say clearly. In fact, Tesla’s growth has been hindered.

While Tesla’s sales are stagnant and China’s new energy vehicles are booming, the logic of overseas pure electric vehicle market growth seems to be challenged.

Kang Linsong, Chairman and CEO of Mercedes-Benz Group Co., Ltd., said at the annual general meeting that he would abandon the all-electric vehicle plan. Kang Linsong said that in view of the fact that the popularity of electric vehicles has not reached expectations, Mercedes-Benz will no longer adhere to the original goal of fully turning to electric vehicle sales in major markets before 2030.

GM also made a strong statement that "the company will fully turn to electric vehicles in the future", and it also ended in vain, giving up the goal of producing 100,000 electric vehicles in the second half of 2023 and producing 400,000 trams in the first half of 2024.

According to Edmunds’ insight, in the global market, the average selling price of electric vehicles is $59,400, which is much higher than the $44,800 of traditional fuel vehicles.In today’s global economic slowdown and shrinking demand, it is inevitable that the market space of pure electric vehicles will not be broken if the price is too high.

This is also reflected in Tesla’s sales in the first quarter of this year. The data shows that Tesla delivered a total of 386,810 vehicles, far below the analyst’s previous average expectation of 449,080 vehicles. This is also the first time that Tesla has fallen below the 400,000-vehicle mark since the third quarter of 2022, which is over 8.5% lower than the delivery of 422,875 vehicles in the first quarter of last year.

According to data from Carisyou, a Korean research institute, and the Ministry of Trade of Korea, Tesla sold only one car in the Korean market in January this year in South Korea, the home base of international cheap fuel vehicles.(You are not mistaken).

As a result of various problems, Tesla did not give a clear sales guide in 2024 at the latest financial report meeting, which triggered concerns about Tesla’s sales in the capital market. Tesla’s share price has dropped from the highest point of $299 last year to $172 today, which is not a small drop. It can be seen that investors do not have too many illusions about Tesla’s short-term and medium-term future performance.

Tesla’s share price performance (since listing)

Judging from the changes in the international situation, the situation has not fallen to the side of Musk.

Take the American market for example, in order to protect the interests of traditional automobile manufacturers, they relaxed the emission standards of automobile exhaust, and the support for pure electric vehicles began to decline. In 2032, the proportion of pure electric vehicles in new cars was reduced from 67% to 35%, and it was also stipulated that power batteries must be produced in China, so that consumers could get the government’s price subsidy of $7,500 per vehicle.

A similar situation has occurred in the European market. With the news that European automobile giants have suspended the development of new energy automobile industry or stopped the transformation of new energy in order to maintain their advantages in the field of fuel vehicles, automobile giants have begun to play a game with policies in terms of economic and social effects.

The final result of these games can only make the development trend of European and American automobile industry and new energy vehicles drift away.

Write it at the end

It can be seen that with the rise of new energy automobile enterprises in China, European and American automobile enterprises have suffered a huge impact, and returning to the fuel vehicle market is more like a forced choice than taking the initiative.

Musk himself had a clear judgment on this:

Under the unfavorable situation, the new moat he chose for Tesla is autonomous driving and its derivative Robotaxi market. This basically means giving up the cheap car market, and it is also an attempt to gain more added value.

Whether this direction can bring enough business increment to Tesla, at least at present, is uncertain-especially if the domestic Baidu unmanned taxi has not made enough progress and effect.

For Musk, it is not a comfortable role to be caught in the political and economic games of major countries, but it is also the price of success in that year.

This article comes from WeChat WeChat official account:Tide wave (id: wave-biz), Author: Hu Mo, Editor: Yang Xuran

"I am an engineer myself. I have done both hardware and software. Therefore, our zero run will definitely have the culture of engineers. " The founder of Zero Run once said this.

The Science and Technology Man Created by The Big Bang Theory

Zhu Jiangming and his zero-run car really have a "science and technology man" temperament. Everything is "technology is king" and independent research and development are highly respected. Judging from the S01, the first mass production car with zero running, all the core components should be self-researched, and there is already the strength of "no madness and no survival".

The industry is not the first to build such a "science man". Nowadays, the zero-running car is very much like the first electric car enterprise in China. Zhu Jiangming’s engineer temperament is also reminiscent (known as "the boatman").

BYD started its electric layout at the end of its own brand, and it caught up with the best time of electric car in China. Soon after the zero-run car started, can the running method of "self-research"+"self-construction" still win?

The tactics of technical men: super learning ability

Zhu Jiangming, founder of Zero Run Car, and Wang Chuanfu, president of BYD Co., Ltd.

"We started with the enterprise dispatching machine in 1993 and transformed the security equipment in 2001. We have experienced two successful entrepreneurial processes from 0 to 1." Zhu Jiangming recalled and said.

In 1993, 26-year-old Zhu Jiangming and Fu Liquan, the current chairman of Dahua Co., Ltd., pooled 5,000 yuan to set up Dahua in a primary school in Hangzhou and started their business. Zhu Jiangming, who graduated from Zhejiang University majoring in telecommunications, is good at embedded algorithm and chip-level combination of software and hardware at the bottom of the computer, and Dahua originally used this embedded technology for enterprise dispatching machines.

In 2001, Dahua’s main business turned to security, which made Zhu Jiangming completely a layman. By studying and studying, Zhu Jiangming led the team to develop 8-channel embedded DVR in 2002. This technical breakthrough in the security industry has enabled Dahua to enter a period of rapid development, laying a foundation for the future development of Dahua.

Zhu Jiangming, who once couldn’t tell all the camera parameters, became an expert in video security technology. HDCVI (high definition composite video interface) video transmission technology invented by Zhu Jiangming was officially released by Dahua in 2012, which triggered a technical earthquake in the field of video transmission.

As a coaxial high-definition transmission technology, HDCVI can realize the transmission of megapixel video over 500 meters, breaking through the bottleneck of resolution of traditional analog technology. In 2013, the international HDcctv Alliance announced the acceptance of HDCVI as an international standard, and HDCVI technology became the first technical specification in China security industry to be included in the international standard. In December 2014, HDCVI technology and standards were included in GA/T1211-2014 "Technical Requirements for Security and Prevention of HD Video Surveillance System".

With the invention of HDCVI alone, Zhu Jiangming opened the door to wealth and freedom. "Every year, relying on HDCVI, Zhu Jiangming can receive a lot of patent fees from all over the world." Insiders said. However, Zhu Jiangming is still not satisfied. In 2015, he decided to create a zero-running car and wanted to realize the third "0 to 1" change in his life.

Boatman: You can make everything yourself.

Wang Chuanfu, a fellow science and engineering man, is one year older than Zhu Jiangming. The advanced story of "Brother Boatman" has long been a household name in China. Comparing the two, "science and engineering men" seem to like to do the challenge of "nothing can be done".

Wang Chuanfu likes to manage enterprises by means of management technology. "Technology is king and innovation is the foundation" is the fundamental development concept of BYD put forward by Wang Chuanfu. Wang Chuanfu does not impose restrictions on BYD. He thinks that everything can be made by himself, and what is made is more useful than what is bought at a high price. He thinks that technology patents are all’ paper tigers’. The remarks that "20 engineers support a mechanical arm" and "cars are just a pile of steel" make "science man" Wang Chuanfu look simple, arbitrary and conceited. He enthusiastically pursues technological innovation. He uses strong creativity and indigenous methods to break the technical blockade. He despises unreasonable business order and game rules. His growth mode is simple and direct: if you don’t help me, I will do it myself.

In 2003, BYD produced more lithium batteries than Sanyo, Sony and Panasonic, accounting for 60% of the global market. At that time, Japanese companies had established a highly automated battery production line, and the mechanical arm could replace a lot of labor. When representatives of Japanese enterprises visited BYD, they were amazed at the production efficiency of BYD’s semi-automatic+manual "human sea tactics". In that crazy era, Wang Chuanfu made full use of domestic low-cost human resources to subvert the monopoly position of Japanese battery industry at that time.

In 2003, BYD began to transform into the automobile industry. Wang Chuanfu’s decision inevitably met with some opposition. Wang Chuanfu said confidently, "I am determined to do it, and I believe it can be done. Judging from the road BYD has traveled, more than 98% of my decisions are correct! " "I will work as a car for the rest of my life!"

Shortly after purchasing Qinchuan Automobile, Wang Chuanfu asked his men to collect several boxes of books on automobile technology for him in bookstores in Xi ‘an and Beijing. When Wang Chuanfu invited car design expert Lian Yubo to join BYD, Lian Yubo asked, "Do you know anything about cars?"

Wang Chuanfu honestly replied, "I like cars. I have read hundreds of books."

At the beginning of BYD’s transformation, it was sung down by the capital market and its stock was badly sold. Wang Chuanfu once promised fund managers that entering the car "will bring the company 30 million profits and the production and sales of 30,000 cars one year later". As a matter of fact, in the first two years of BYD Auto, it only spent a lot of money to build a "Fleur" model.

BYD’s First Model-"Fowler"

"Fowler" is basically BYD’s "behind closed doors" product, and the dealers can’t laugh and cry when they look at the "four unlike" in front of them, so the sales volume will naturally not be ideal. In 2005, BYD’s annual report showed that BYD sold only 15,993 cars, with a loss of 91.3 million RMB.

How to build a good car in a short time? BYD adopts reverse research and development. The so-called reverse research and development is to disassemble mature cars, learn from the advantages of other people’s products and develop their own products in reverse. This is more time-saving than saving R&D funds from 0 R&D..

In 2005, BYD launched the first car that really opened the market for BYD-"F3". Even Wang Chuanfu was surprised. In 2006, Wang Chuanfu said, "The current hot sale is completely unexpected. At first, I thought it would be more satisfactory to sell 2,000 units a month. However, according to the current sales capacity, we can walk 10,000 units a month. " Why can "F3" succeed? Because F3 was almost a replica of the best-selling car Toyota Corolla at that time, and the price of F3 was only half of the former.

BYD F3, a replica of Toyota Corolla

Like making batteries, BYD has almost completely produced its own products from production line to automobile parts assembly. At that time, BYD workers said that except for glass and tires, everything on the car was made by BYD itself; It seems that BYD, who has only been in the business for two years, has accomplished an impossible task, which has greatly saved the manufacturing cost and formed a market advantage.

In 2006, BYD quickly launched F3e, an iron-lithium electric vehicle, based on F3 platform. The motor, reducer, battery components and control system of F3e are all developed and produced by BYD. Although the F3e electric vehicle was not successful at that time, it still showed Wang Chuanfu the advantages of electrification. BYD concentrated its R&D efforts on the research and development of its first-generation hybrid technology DM module. At this point, Wang Chuanfu began an all-round attack on fuel vehicles, electric vehicles and automobiles.

Today, BYD has almost become an all-round player. We can produce 2.0T in-cylinder direct injection, dual-clutch DM plug-in module that can be compared with Toyota Prius, and a three-electric technology platform including battery manufacturing, etc. In the "China Automobile Technology Development Report" released in December 2017, BYD’s patent technology is ranked first among mainland automobile enterprises.

Zero Run: Self-research+Self-creation

Can BYD’s "all self-produced" model still work today?

Lingpao Jinhua base welding workshop

"All car companies with a long history will eventually go to the road of" self-research "and" self-made ",and zero running is only the first to make the right choice." Zhu Jiangming said. Unlike the internet, zero running is low-key and crazy. In the 40 months since the establishment of Zero Run Automobile, we have carried out the values of "technology is king" of science and engineering men, and "the foundation for IT people to build cars-insisting on independent research and development of core technologies", which makes us seem to see the shadow of BYD in that year.

Independent research and development of automatic driving system

Different from BYD’s generation of car-making forces more than a decade ago, the focus of automobile development is on automobile mechanical technology. Vehicle design; Nowadays, the new trend of automobile electrification and intelligence has put forward new topics for the new generation of car makers.

"50%-60% of electric vehicles are actually related to electricity, and the composition of electricity is not necessarily less than that of machinery. The underlying technology will have a large number of electrical components to cooperate and interact. For the next generation of automotive hardware, especially the underlying electronic and electrical architecture technology, zero running based on Dahua technology background is completely advantageous. " Zhu Jiangming explained.

"Zero Run is the second vehicle manufacturer in the world with complete independent research and development capabilities for smart electric vehicles." Zhu Jiangming said confidently.

Different from the situation that other manufacturers rely on, Zero Run benefits from the technical advantages of Dahua Co., Ltd., and the cameras, sensors, AI autopilot chips, core software and algorithms involved in technology have been independently developed. At present, the zero-run car has achieved L2.5-level automatic driving, which can support L3-level remote upgrade. In 2020, it is planned that all models of zero-run cars will achieve L3 level through software upgrade, and in 2021, L4/L5 automatic driving test will be carried out in a small scale. After 2025, it will reach the L4/L5 level of mass production.

Comparison Table of Intelligent Driving Assist Function between Zero Run S01 and Competing Vehicles

What is the relationship between the chips in the lowest layer of intelligent vehicles? What is the embedded algorithm? Zhu Jiangming and Dahua, who have been dealing with electrical architecture technology for 20 years, have taken a fancy to the development opportunities of automobile intelligence and electrification, which is also the advantage of zero-running into the electric vehicle market. In addition, more importantly, the core technology of domestic intelligent networked automotive technology is missing, and Zero Run wants to fill the gap in automotive smart chips and intelligent algorithms. Zero-run car is jointly developing AI autopilot chip-Lingxin 01 with Dahua Co., Ltd. According to the relevant personnel of Zero Run, Lingxin 01 will have the ability of deep autonomous learning, and its computing power will reach the mainstream level in the industry, while supporting multi-chip flexible combination. At present, Lingxin 01 has entered the stage of integration verification, and it is expected to carry out real vehicle testing in the second quarter of next year.

Self-developed body platform

Different from BYD’s reverse research and development, Zero Run claimed that it had developed three body platforms-T-Platform, S-Platform and C-Platform from the beginning. The Zero Run S01 is the first mass production model based on S-Platform.

S01 is based on the design of electric vehicle platform, and the components of the whole vehicle, such as body, chassis, powertrain and battery pack, are all designed independently by zero-run. S01 curb weight is only 1240 kg, and the battery module accounts for 80% of the vehicle width. In this numerical performance, Tesla is 78%, while the average value of the electric vehicle industry is 60%. Its body-in-white weighs only 215 kg, accounting for 17% of the curb weight, while the average value of the body-in-white of electric vehicles is 20~25%.

Zero Run S01 Body-in-White

Platform S is designed with a toughened cage structure around the protection of the passenger compartment to ensure that the passenger compartment has sufficient rigidity and strength. The platform expansibility was also considered in the early stage of research and development, and the architecture can be extended from the current S01 two-door four-seat to five-door cars and models. S01 body-in-white roof adopts embracing laser welding technology to optimize the solder joints; The car body adopts a large number of processes such as thermoforming and rolling, and the proportion of thermoforming and high-strength steel is over 70%. Important anti-collision paths such as A-pillar /B-pillar/door anti-collision beam and front cabin are thermoformed, and the tensile strength reaches 1300Mpa；. The inner and outer doorsills are rolled, and the tensile strength reaches 1180Mpa.

Self-developed "Three Electricity" System

"Hercules" electric drive assembly

As the core three-electricity technology of electric vehicles, zero-running is all independently developed except batteries. Zero-run S01 electric drive is code-named "Hercules". Zero-run is fully developed forward, and the lightweight design scheme of "three in one" of motor, controller and reducer and "five in one" of motor controller is adopted.

Hercules is divided into an upper part and a lower part. The upper part is a "five-in-one" motor controller, which is divided into an upper case and a lower case.
Case) section. The upper box part is DCDC (vehicle power supply), MCU (motor controller) and PDU (high voltage distribution module), and the lower box part is VCU (vehicle controller) and OBC (on-board charger). The lower part is the driving motor and reducer. The upper part and the lower part are connected by a flexible fixed damping mechanism to form a "three-in-one" system.

This set of electric drive assembly has completed the accelerated life test of 500,000 kilometers, and it is also the first one in China to complete 120,000 continuous peak power start and peak power energy recovery braking cycle life tests. At present, it has mass production capacity. Compared with the traditional design with the same performance, "Hercules" reduces the weight by 30% and the volume by 40%, and the overall mass is only 91kg, but it still achieves the maximum power of 125kw and the peak torque of 250Nm； as the electric drive assembly. The highest efficiency of the system reaches 93.6%, and the high efficiency ratio exceeds BMW i3 by 94.49%.

Comparison Table of Motor Efficiency and Electric Control Parameters between Zero Run S01 and Competing Vehicles

After the electric drive assembly, we are looking at the battery pack of S01. The power battery PACK of a zero-run car is all independently developed except the battery cells, which is "the highest degree of independent research and development of battery packs in domestic automakers except BYD, including modules, PACK, BMS hardware and software". Due to the integrated thermal management scheme of cold and heat, the charging and discharging efficiency of the system reaches 97.7%, and the discharging efficiency can still reach 92.5% in the area of -15 degrees. The four-in-one shunt is used for current detection, which makes the SOC accuracy reach 3%; Adopt single cell bipolar double insurance to reduce the risk of thermal runaway diffusion; The battery box shell adopts integrated aluminum casting process, which reduces the total weight of the box by 40%.

Comparison Table of Battery Pack Parameters between Zero Run S01 and Competing Vehicles

Although Zhu Jiangming thinks that Zero Run wants to be Huawei in the automobile industry, as far as the current measures of Zero Run are concerned, they are more like taking the old road of BYD. Zhu Jiangming may not be as fanatical as Wang Chuanfu, but the values of "science man" and "technology is king" will make them reach the same goal by different routes.

S01, the first production car with zero running.

Is it reliable for "science man" to build a car? Judging from the successful example of BYD, the hard-core ones are very reliable. However, it is not enough to drill only in technology. It is indispensable to do a good job in "humanity" and "feelings" of automobiles, and "science and technology men" also need to open their arms and embrace the world.

BYD’s success is not only due to its tireless innovation, cost reduction, hard battle, "reverse development", its ability to appeal to consumers, but also its necessity to open the market. In the past year or two, BYD’s "Dynasty Series" has sold well, not only because of the three-electric technology, 2.0T engine, dual-clutch gearbox and DM hybrid, but also because of Wolfgang’s dragon face. BYD has gone a long way from a technical expert to a product expert, and it is still on the road.

Nowadays, in terms of intelligence and electrification, traditional car companies at home and abroad have begun to display their technical reserves and launch wonderful products. It’s a long way to go to the technical master. Let’s see if he can beat his opponent. (End)
