　　Recently, a celebrity posted a series of Weibo, expressing his views on whether audio recording, video recording and photography should be banned at concerts, which has aroused widespread discussion. The opinions of netizens vary. Some think that since they have paid for the concert, they should be in charge of themselves, and that taking photos and recording videos is only for sending Moments and should not be restricted. Some think that since they come to listen to live performances, they should respect the requirements of the performers, fully commit themselves, and should not use mobile phones. Some netizens think that audio recording and video recording infringe the copyright of the organizers, but photography is not used for profit, does not violate portrait rights, and prohibiting photography is a bit overkill. Can you record, video or take pictures when watching live performances? How is it defined in law?

　　"Note to the audience" is a contract

　　On the back of the performance tickets purchased by the audience, most of them are printed with "Audience Instructions", the most common clause of which is "Without permission, audio, video and photography are prohibited on the spot." This type of audience information is actually a format contract between the ticket seller, the ticket buyer and the user. The so-called format contract refers to a contract that is pre-drawn up by one party for repeated use and cannot be negotiated by the other party at the time of signing. Like the tickets we often come into contact with, the "Audience Instructions", "Visiting Instructions", "Park Instructions" and "Passenger Instructions" in the ticket are all format contracts. Because of its wide use, it is generally tacit that after appropriate prompts, the ticket buyer has been informed and approved of this type of contract requirements at the time of ticket purchase.

　　Maybe everyone is a bit "talking about the tiger changing color" when it comes to the format contract, but if the party providing the format clause exempts its liability, increases the liability of the other party, and excludes the main rights of the other party, the format clause should be invalid. If the format clause is valid, then when the ticket holder accepts the contract, it should abide by the requirements of the corresponding clause; if it is invalid, the ticket holder is not bound by the invalidation clause. So, in the "Audience Notice", the "No audio, video and photography on the spot without permission" clause is invalid?

　　Unauthorized audio and video recordings infringe copyright

　　Copyright includes the right of publication, the right of authorship, the right of modification, the right to protect the integrity of the work, the right of reproduction, the right of performance, the right of information network dissemination, the right of filming, the right of compilation and other rights. Article 38 of the Copyright Law of the People’s Republic of China stipulates that performers have the right to license others to broadcast live and publicly transmit their live performances and receive remuneration for their performances; the right to license others to record and receive remuneration for their performances; the right to license others to copy and distribute the audio and video products of their performances and receive remuneration; and the right to license others to disseminate their performances to the public through information networks and receive remuneration. At the same time, Article 47 stipulates that without the permission of the performer, live broadcast or public transmission of his live performance, or recording his performance, is an infringement, and shall, according to the circumstances, bear civil liabilities such as stopping the infringement, eliminating the impact, apologizing, and compensating for losses.

　　According to the above legal provisions, in a narrow sense, unauthorized audio and video recording during live performances is an infringement; and in a broad sense, the author believes that static designs such as stage arrangement, performance costume design, and performer modeling during performances also condense the creative work of the organizers, making public the results of a large number of intellectual activities of the organizers of the performance department, and restricting photography are also acts of performers and organizers to protect their own copyrights.

　　When the audience purchases tickets to watch the performance, they actually enjoy only the right to watch the artistic performance provided by the performer and the organizer, and do not obtain the authorization to copy, record and disseminate the performance. The above format clause does not exclude the main rights of the audience, just as when visiting a museum, there are some exhibits that can only be appreciated and not allowed to be photographed due to the fact that the copyright has not expired.

　　Therefore, whether from the perspective of copyright protection, or from the perspective of the legality and rationality of format contracts, audiences should abide by the regulations prohibiting audio recording, video recording, and photography. Especially now that live broadcast software is very popular, many live audiences broadcast live performances through software platforms without permission, which directly infringes the copyright of performers.

　　Due to the above reasons, it is recommended that the general audience carefully read the "Audience Instructions" when watching live performances such as concerts, concerts, and dramas, abide by relevant regulations, do not use cameras, mobile phones, and other electronic devices to record, respect the intellectual achievements and legitimate rights and interests of others, and at the same time bring themselves a better viewing experience.

　　Unauthorized photography or infringement of portrait rights

　　Does taking photos at concerts infringe upon the image rights of celebrities? When it comes to portrait rights, everyone is not unfamiliar with it. Article 100 of the General Principles of the Civil Law of the People’s Republic of China stipulates: "Citizens enjoy portrait rights, and without their consent, they shall not use their portraits for profit."

　　But it does not mean that other people’s portraits can be used at will without the purpose of profit. Article 120 of the General Principles of the Civil Law also stipulates: "If a citizen’s right to name, portrait, reputation, and honor has been infringed, he has the right to demand that the infringement be stopped, his reputation be restored, the impact be eliminated, and an apology be made, and he may demand compensation for the loss." In fact, the right to portrait, like the right to name, is an exclusive right. Without his permission, others cannot use it at will. That is to say, in the absence of illegal obstacles (such as retention of evidence, coverage, and the issuance of a "wanted notice" by the public security organ, etc.), the production, reproduction, dissemination, and exhibition of other people’s portraits shall be subject to his permission. Otherwise, the right to portrait of others shall be infringed.

　　Malicious processing and defacement of other people’s portraits not only infringes the right of portrait, but also constitutes damage to the right of reputation. For example, the unauthorized use of celebrity photos to make peripheral products for sale, advertising, etc., are all acts of infringement of portrait rights. In addition, most of the popular emojis are made without their consent, which is also an act of infringement of portrait rights. If they are used for commercial purposes, they also need to bear corresponding compensation liabilities.

　　It should be noted that in order to protect the public’s right to know, artists, well-known public officials, etc., as public figures, have the obligation to tolerate a certain degree of photojournalism in public. And for shooting that is not for the purpose of photojournalism, under the current laws of our country, there is still some controversy as to whether it should be regarded as an infringement of portrait rights. However, without permission, shooting in the private life of public figures, whether for news purposes or simply shooting without dissemination, is a candid shooting and may be investigated for civil liability. In daily life, everyone should know how to protect their privacy rights, portrait rights, and reputation rights, and at the same time respect the legitimate rights and interests of public figures.

Andy Lau "kissed" with Big S in public, claiming to yearn for "polygamy"

　　　　　　　 Andy Lau was Big S’s idol for many years. When he learned that he was going to cooperate with Andy Lau, Big S was very nervous, and it happened that the first scene between the two was a kiss scene. Looking back on the scene at that time, Big S still remembered it vividly, "My sister and my mother knew that I was going to shoot a kiss scene with Andy Lau, and they all excitedly asked to watch it.

　　　　　　　 In the interactive game at the scene, Andy Lau had to satisfy the fan’s request to "offer a kiss". When Xu Jiao and Shi Yunpeng, two young actors, kissed him instead of the fan, Andy Lau took the initiative to ask Big S to kiss him, "Don’t Big S come up? I want to kiss her." Facing the invitation of the idol, Big S was a little shy, but he didn’t expect Lau Dehua to "anxiously" go forward and kiss Big S, but, cunning, he used his hat to block both of their faces and offered a fake kiss by borrowing. In the film, Andy Lau from the future and Big S have only been in a relationship for 30 days, and he has never forgotten his dead "wife" Fan Bingbing. The affectionate Liu Tianwang wants to have two "lovers" at the same time, "I can’t choose between them. The future world I envision has resumed’polygamy ‘."

　　　　　　　 On the same day, Andy Lau brought the ambiguous part of the film with Big S to the scene, not only acting very gentleman, but also often humorously showing "love" to Big S. When asked about the type of girl he likes the most, Andy Lau confessed that it is a girl with long hair, "Big S now has long hair, but it used to be short hair, like a boy. It’s just that we met too late. This is all fate." When Big S revealed his penchant for eating peanuts, Andy Lau said, "Because of my high cholesterol, I have quit for a year." Then he did not forget to add a sentence, "Alas, I quit after I separated from Big S. It’s pointless to do anything without her." A humorous "confession" amused the audience with laughter and screams.
　

Recently, a reader initiated a small survey on our exchange group – Huawei asked which of the two cars, the new M7 and the ideal L7, would you choose?

Here are the responses from readers in the group:

That’s right, all ask the world about the new M7. Correspondingly, the order of the new M7 broke through 50,000 units in 25 days.

With this new car orders surge, the greatest sense of crisis is ideal.

According to 36Kr, in the last week before the festival, Li Auto held a strategy meeting to discuss its development direction in the next 5-10 years. One significant adjustment was that it was ideal to replace the first strong opponent by BYD with Huawei.

Although Huawei has always insisted on not building cars, its influence in the car circle cannot be shaken, and asking the new M7 to "come back to life" in a short period of time is the best proof. So after Cyrus hitched a ride, Chery was also waiting for Huawei to fire its own new energy vehicle.

Not only ideal, other car companies are also beginning to pay attention to this new opponent. Huawei’s tentacles are getting longer and longer, who will be the next to be squeezed off the table?

What are you afraid of Huawei?

The success of the new M7 is based on the popularity of the masses.

The public opinion of the mountain and tsunami can be seen and touched, and these can be converted into real orders. It is reported that Huawei aims to ship 60 million – 70 million smartphones in 2024, double the annual shipment (30 million) in 2022.

With the appeal of Huawei mobile phones in the end point market, Huawei’s empowered Q models have also begun to reflect.

During the National Day holiday, the new M7 has a maximum of 7,000 units in a single day. Since its listing in mid-September, the cumulative number of units has exceeded 55,000.

This achievement also made Yu Chengdong sigh "it’s not easy". Of course, in terms of product strength, the new M7 also has enough confidence. The starting price of the new M 7.2498 million yuan is 40,000 cheaper than the old model.

Huawei has invested 500 million yuan in research and development, and has made upgrades to the chassis and performance, space design and layout, and most importantly, intelligent driving.

The intelligent driving and intelligent cockpit are the killer features of the new M7.

The new M7 is equipped with HUAWEI ADS 2.0 advanced intelligent driving system, and the most significant change is the addition of a lidar, which has the ability to assist driving in high-speed, urban, parking, and other scenarios.

HUAWEI ADS 2.0 is equipped with 27 sensors including 1 overhead lidar, 3 millimeter wave radars, 11 high definition visual perception cameras and 12 ultrasonic radars. It can realize NCA function based on BEV large model, road topology inference network and joint planning control without high definition map.

This is also Huawei’s greatest reliance. The urban smart driving pilot assistance (urban NCA) function will cover urban areas and expressways across the country in December this year.

The ideal AD Max 3.0 city NOA navigation assistance driving system has only been pushed to closed beta users since the second quarter of this year. It is expected to be pushed to more than 100 cities in China by the end of this year.

So from this round, Huawei is indeed far ahead, and even Li Xiang himself admits that their intelligent driving is half a year late.

And Huawei empowered the world, from birth to entry, as Huawei managing director, end point BG CEO, intelligent car solutions BU chairperson of Yu Chengdong, played a crucial role.

From "Yu big mouth" to "far ahead", Yu Chengdong can be said to be a "marketing wizard", but Lao Yu "although big mouth", but what goes around is technology.

The marketing focus was also technology. He was extremely good at packaging a certain technology in language, and then giving a review – far ahead.

Previously, Yu Chengdong said in an interview with the media that Huawei’s goal in entering the automotive industry is to be first, because no one will remember the second, and he once bluntly said that "the cattle I bragged about have basically been realized."

In this regard, Yu Chengdong is actually very similar to Li Xiang, the "king of Weibo", and he is a sharp-edged person in personality.

Therefore, Yu Chengdong was a person who understood both technology and marketing. Even as a new player, he could cut into the competitive Red Sea automobile market with a attitude of dimensional reduction.

How can the ideal be broken?

When a car company sells its cars better and better, and its competitors become more and more numerous, its original weaknesses will gradually surface. This is a good example of the reverse trend of the new M7.

The ideal obviously realizes this.

– His investment in intelligent driving has been slightly conservative and cautious.

36Kr reported that at this ideal autumn strategy meeting, intelligent driving became the core topic. Li Xiang reflected and concluded at the meeting that investment in intelligent driving should start half a year earlier, that is, from the middle of last year, we should go all out, rather than starting to increase efforts at the beginning of this year.

An important consensus was reached at the meeting, that is, "make up for the missed classes, and break the game by strengthening investment." After all, the ideal account still has 70 billion cash.

At the meeting, Wang Xing, Lu Qi and other shareholder bosses also said that "increase investment, and even sacrifice some efficiency" when talking about their attitude towards ideal smart driving.

Reviewing the time node of Ideal Smart Driving’s research and development, Ideal announced the start of high-precision maps in 2021, and only landed on high-speed NOA in December of the same year. In August 2022, Ideal officially delivered the Smart Driving 2.0 system on the L series.

Since then, the ideal of intelligent driving has been divided into two products: AD Max and AD Pro. AD Max 2.0 uses NVIDIA OrinX chip and Wesai car-grade lidar to deliver the first high-speed NOA product for visual fusion lidar; AD Pro 2.0 uses Horizon Journey 5 chip to deliver the first high-speed NOA product for pure visual perception.

Until September this year, Li Auto released the closed beta of urban NOA technology and commuter mode, and announced its city-opening plan, but it is worth noting that Li Auto’s city-opening plan is only limited to early bird users.

Under such a rhythm, it is not difficult to feel the actual landing ability of Li Auto’s intelligent driving function, which has a certain gap with friends such as XPeng Motors and Huawei.

Therefore, at this strategic meeting, the development of intelligent driving was also raised to an unprecedented level within the ideal.

First, the person in charge of the ideal internal perception and system was promoted to vice president respectively. On the third day after the National Day, Li Auto’s official account released more than 50 smart driving club recruitment positions.

Which covers the software algorithm, large model, vehicle hardware, testing, operation and other fields, intelligent driving algorithm engineer and a series of positions, most of the starting salary of about 30,000 yuan, large model and autonomous driving related positions, the highest monthly salary can reach 90,000 yuan.

At present, there are as many as 63 job openings for Ideal Smart Driving, covering visual perception algorithms, autonomous driving models, simulation platforms, map data engines, and other categories. The smart driving R & D team has also increased to 800 people.

All kinds of actions show that the weight of the smart driving business has been greatly increased within the ideal. Correspondingly, in the face of the current strong counterattack of the new M7 in the world, the ideal at this stage has decided to take advantage of its strengths and avoid its weaknesses, continue to strengthen the product longboard in the home market, and no longer compete with the new M7.

According to a report by 36Kr, the sales side has also changed its language, and does not take the initiative to mention the M7. If a car owner asks, they will say that an L6 model will be launched next year, which is the same price as the M7.

In addition to this, Li Auto’s product SOP plan has also been extended to 2027. During this period, Li Auto’s technology platform will experience an earth-shaking iteration. It is expected that by 2026, a new generation of technology platforms will be launched, with fully autonomous driving capabilities.

The two will fight

At the strategy meeting, many aspects of the ideal were planned, and the sea plan was also mentioned.

Ideally, going to sea will not be the ideal strategic focus for a relatively long period of time, and it may not be seriously considered until 2028. Before that, parallel exports will be the main focus.

In July this year, Li Xiang himself also sent a Weibo saying that Li Auto will not consider overseas markets before 2025, and will concentrate all resources to achieve the 2025 goal: to achieve the first sales volume of all luxury brands in the Chinese market, the annual delivery volume reaches 1.60 million vehicles, and to achieve revenue of 500 billion yuan.

The ideal is lofty, but it is indeed possible to achieve. Only 8 years after its establishment, the ideal has become the second most valuable car company in China after BYD. In 46 months, it has achieved the delivery of 500,000 vehicles.

How did Li Auto do it?

Li Xiang has publicly given the answer that growth is the core driving force of Li Auto, and every time he encounters a bottleneck, it is a time to frantically absorb growth. In his dictionary, growth is a closed loop composed of two parts, one is learning, the other is training, that is, practice.

Li Xiang himself is a very good learner and a reflective person, and the learning object is Huawei, which is also a competitor.

As early as June, Li Xiang released a small essay late at night, in which he reflected on the reason why the ideal ONE was discontinued early. Li Xiang admitted that it was because of the release of the original Q-World M7 that Huawei’s super capabilities directly caused the sales of the ideal ONE to collapse and stop production early, and the team was crippled.

In the case of failure, the ideal choice was to learn from Huawei. Li Xiang said that all the ideal management teams had purchased at least 10 Huawei public books to read.

Discovering that the painful problems encountered by Ideal in Product Research & Development, sales and service, supply manufacturing, organization and finance, etc., were solved by Huawei more than a decade ago, or even 20 years ago, which gave him a great shock.

And the ideal implementation of a talent rank system similar to Huawei’s, breaking down the ranks into more details, such as the original P9 sequence corresponding to more than 20 levels of the new rank, which can make "the promotion speed will be faster and have an incentive effect".

The same extended-range technology, similar product positioning and segmentation areas, make the world and the ideal destined to be entangled with each other. The old M7 in the world has impacted the ideal ONE, and now the new M7 has made the ideal feel the crisis again.

There will be a battle between the two, who will win? Another question is, who will you choose for the ideal L7 and the new M7?

　　[Autohome News] On June 9, Geely (|) debuted at the 2023 Chongqing Auto Show. The new car launched a total of 5 configurations, and the price range is 13.87-17 3,700 yuan.

China children’s programming market has huge room for growth in the future.

Children’s programming education is to cultivate students’ computational thinking and innovative problem-solving ability through programming game enlightenment, visual graphic programming and other courses. For example, in the process of making a small animation, students split tasks, drag modules and control the progress themselves, so as to understand the concepts of "parallelism", "event handling" and "goal realization". It is mainly aimed at teenagers aged 3-18.

In 2014-2019, there were frequent policies related to children’s programming education in China, and the policy support continued to increase. At present, the teaching scenes of children’s programming education in China are mainly divided into three categories. At present, children’s programming education enterprises take the B-end as the main style, supplemented by the C-end. By the end of February, 2020, there were 7,110 children’s programming companies in China, with Guangdong Children’s Programming Company leading the country, and the top 10 children’s programming education institutions were headquartered in Shenzhen, Beijing and Hangzhou. In 2018, the corresponding age population of children’s programming industry in China is about 236 million. In 2019, it was about 237 million people. China’s children’s programming market has huge room for growth in the future.

1. The development of children’s programming education in China has attracted much attention.

In 2014-2019, China’s children’s programming policies were released one after another. The country has realized the importance of education, and issued many related policies to encourage and support the continuous development of programming education and information education, and promote the popularization and deepening process of programming education at the national basic education level. The policy covers key provinces and cities such as Zhejiang, Shandong, Jiangsu, Tianjin and Chongqing.

2. Distribution of teaching scenes of children’s programming education in China.

The teaching scenes of children’s programming course are divided into three categories: non-public educational institutions, public educational institutions and families. By investigating the enterprises in the industry and comparing the landing degree in three scenarios, it is concluded that the current children’s programming education enterprises mainly adopt B-end, supplemented by C-end.

3. The headquarters of the top 10 children’s programming education institutions in China are concentrated in Shenzhen, Beijing and Hangzhou.

The children’s programming education industry in China has risen rapidly in recent years. With the blessing of multiple factors such as policy support and market maturity, children’s programming institutions have ushered in their own enthusiasm in the cold winter of capital. According to the data of Internet Weekly, the top 10 children’s programming education institutions in China are ranked as follows:

4. The number of children’s programming companies in Guangdong Province leads the whole country.

China’s children’s programming is still small in scale and relatively scattered in institutions, mainly distributed in first-tier cities such as Beishangguangshen and Shenzhen, and offline institutions are also mainly concentrated in first-and second-tier cities.

By the end of February, 2020, there were 438 children’s programming companies in China. In 2019, there were 7110 children’s programming companies in China. By the end of February 2020, domestic children’s programming companies were mainly located in Guangdong, Jiangsu, Shandong and Zhejiang, with 11,770, 3,529, 2,265 and 2,044 children’s programming companies respectively.

5. The overall corresponding age population of children’s programming industry in China is increasing year by year, and it is about 237 million in 2019.

The minimum age of children’s programming students in China is about 3 years old. At this stage, children’s cognitive and understanding abilities have reached a certain level and can begin to participate in such training. The oldest participants are 18-19 years old, that is, senior three students, and the population covered by the training generally coincides with the student group corresponding to K12 education. Therefore, Forward-looking Industry Research Institute adds up the number of students in kindergartens, primary schools, junior high schools and senior high schools in the national statistical bulletin on the development of education published by the Ministry of Education every year, and estimates the population aged 3-18 in China. From 2014 to 2018, the population aged 3-18 in China showed a slow growth trend. In 2018, the corresponding age population of children’s programming industry in China was about 236 million. In 2019, it was about 237 million people.

On February 17th, a video about a BYD new energy vehicle exploding and burning on a trailer in Yantai, Shandong Province was circulated on the Internet. According to the video, the towed car on the trailer started to emit smoke, then sparks began to flash at the bottom of the car, accompanied by crackling explosions, and finally it began to burn violently, and the whole car was quickly burned beyond recognition.

BYD Tang DM-i exploded and caught fire during consignment.

According to eyewitnesses, the incident occurred at about 1:10 pm on the 17th, near the East Yard of yantai mountain hospital, Guanhai Road, lai shan. At the time of the incident, the trailer was waiting for the green light at the intersection, but the bottom of BYD’s new energy vehicle towed by the car suddenly splashed with sparks, and there was a crackling explosion. Then smoke billowed, which ignited a fire, instantly wrapping the car body, and the car owners in the same industry drove away. At the critical moment, a nearby sprinkler arrived in time to put out the fire, and the fire was completely extinguished by the firefighters who followed, but at this time, this new energy vehicle had been burned to only one body.

At the scene of the accident, Yantai fire rescuers who came out to the police rescue told the verification media that fortunately there was no one in the car at that time and the cause of the fire was under investigation. BYD’s official customer service only said in the next day’s inquiry that the relevant information has not been received, and the specific reasons are still unknown, and it is necessary to wait for the investigation results to determine.

At present, it is not clear whether the car was consigned after the accident or failed to be consigned by itself, so it is impossible to analyze and define the main causes of its spontaneous combustion and fire. However, according to the live video, it can be found that sparks are constantly flashing at the bottom of the vehicle and crackling explosions are heard at the initial stage of the fire. From this, it can be roughly determined that the battery is indispensable for the violent combustion, and even the fire site may be the battery.

Judging from the body of the live video, it should be BYD Tang’s 2021 DM-i model that caught fire. The car was officially launched during the Shanghai Auto Show in April 2021. There are three models in total, and the price range is 189,800-216,800 yuan.

Tang DM-i is a heavyweight model introduced by BYD to replace the fuel version. According to the official statement, "it took nine years to finally produce this subversive model of Pratt & Whitney Volkswagen". The car is equipped with BYD plug-in hybrid system, which is composed of a turbo-charged 1.5Ti high-efficiency engine dedicated to Xiaoyun-plug-in hybrid of Miller cycle and an EHS electric hybrid system, and adopts Ferrous lithium phosphate "blade" battery dedicated to BYD hybrid.

Blade battery is an innovative product that BYD is proud of in the field of power battery. Tang DM-i is equipped with a power Ferrous lithium phosphate "blade" battery, which is different from the lamination process of BYD EV models, and adopts a winding process. Each group of blade batteries has a biscuit-shaped pole core, and a plurality of battery cells are integrated in series inside each pole core, while the whole battery pack is composed of a plurality of pole cores connected in series, and finally packaged into a "blade" battery. One of the outstanding advantages of this battery is that its heat dissipation capacity is good, and the battery uses Ferrous lithium phosphate as the positive electrode, so its performance is relatively stable, so its safety factor is relatively high in theory.

It is precisely because of this that Wang Chuanfu, Chairman and President of BYD’s Board of Directors, once said at the super conference of "Blade battery is unsheathed and safe in the world" on March 29, 2020, "Blade battery embodies BYD’s determination to completely end the safety pain point of new energy vehicles, and it will redefine the safety standard of new energy vehicles." "New energy vehicles equipped with blade batteries will completely erase the word spontaneous combustion from the dictionary of new energy vehicles."

BYD’s "blade" battery became famous in the first world war because of the puncture experiment, and it was spread in the industry. Later, it was fully promoted and applied in all models of BYD’s new energy, and made great contributions to BYD. Supposedly, such an innovative product should completely reassure consumers, but the reality is somewhat embarrassing for Boss Wang.

In fact, not only BYD Tang DM-i, but also Han DM-i, BYD e6, BYD e2, Qin Pro, Yuan EV, Song Pro DM-i, Seals and Dolphins. Just search the network news, and you will find that BYD’s new energy series vehicles have had fire or spontaneous combustion accidents, and some vehicles are still relatively frequent, and they have emerged from time to time on the network.

Original sin or quality problems in key parts

Take the protagonist Tang DM-i as an example. In recent years, spontaneous combustion accidents are not uncommon. For example, on January 26, 2022, some netizens broke the news that a BYD Tang DM-i in Shanghai caught fire on the way to the trailer. This is really a coincidence. The situation is so similar to this accident that Xiaobian thought it was the same incident at first, and then carefully identified the license plate number and confirmed that it was two accidents. This accident eventually led to the complete burning of the car.

Also in Shanghai, on March 19th, one month later, it was revealed that the BYD Tang DM-i newly mentioned by a car advocate in Shanghai spontaneously ignited in the parking space of the community. According to the information provided by the owner and the chat record, the car caught fire at around 5 am that day, which caused the car next to it to be burned to varying degrees. According to the owner, the car was not charged at that time, but just parked there.

This is only a corner of Shanghai, and it is only a short period of incomplete online exposure news. Search those online news that have not been deleted, and you will find that BYD Tang DM-i spontaneous combustion accidents are all over the place, and there are many more.

Objectively speaking, with the widespread use of new energy vehicles, fire accidents are indeed rising. According to the statistics of the Fire and Rescue Bureau of the Emergency Management Department, in 2021, there were 3,000 fire accidents in new energy vehicles nationwide. It seems inevitable that a hot-selling new energy vehicle will have some spontaneous combustion accidents, but the mistake is that BYD Wang’s boss should not talk too much.

What’s more, such an accident is a very disturbing disaster for any individual consumer. If there are casualties in the accident, it will be a family tragedy. Therefore, it is necessary to explore the causes of spontaneous combustion of BYD Tang DM-i, even Qin Pro, Yuan EV, Song Pro DM-i and so on.

On April 29th, 2022, a recall notice issued by the State Administration of Markets indicated that 9663 Tang DM models produced from September 2nd, 2021 to March 14th, 2022 would be recalled from now on. The reason for the recall is that the installation surface of the battery pack trays of these vehicles is uneven due to manufacturing reasons, and there is a risk of water ingress. "This may cause the electrical circuit of the power battery system to fail. In extreme cases, there is a risk of thermal runaway of the power battery, which poses a safety hazard."

On July 29th, 2022, another recall notice issued by the State Administration of Markets revealed that BYD had expanded the recall scope of Tang DM and decided to recall 52,928 Tang DM electric vehicles produced from April 5th, 2021 to April 18th, 2022 from now on. The reason for the recall is that "some vehicle power battery pack trays are at risk of water ingress, which may cause arcing in the high-voltage system and pose a safety hazard."

In fact, people who don’t understand these technical terms, whether it’s thermal runaway or high-voltage system arcing, may not be too concerned. But in other words, if the common people can understand it, it is: the battery is overheated to the limit, which will cause the battery to burn or explode; As for the high-voltage system, it is simpler to pull the arc. Have you ever seen the transformer switch on? "Zizi" sparks with lightning all the way, and the high-temperature arc generated by high voltage and high current can ignite the surrounding combustible materials in an instant.

Therefore, judging from the spontaneous combustion accidents of DM-i in Tang Dynasty, although BYD conducted cold treatment in most cases afterwards, and did not give specific reasons and follow-up news, it is not difficult to find from the official announcement that the quality control of DM-i in BYD Tang did have serious problems that might lead to spontaneous combustion, so that it had to start a recall.

Returning to this consignment spontaneous combustion accident, although the specific reasons are still under investigation, consumers can also reasonably doubt their quality control. In fact, we fully understand consumers’ concern about safety, but we don’t pay so much attention to the cause or process of the accident. Because no matter whether you are short-circuited, flooded, uneven or out of control, as long as your results lead to fire, spontaneous combustion or explosion, there is virtually no difference to consumers-from car burning to "human purgatory (if you can’t run away)".

As a leading new energy vehicle company, we should pay more attention to the reasonable concerns of consumers, especially the safety concerns, and we should not be negligent. After all, vehicle safety involves many aspects, not only batteries, but also supporting systems, body structure, etc. It is an organic whole, and no one can neglect it. If the quality control is neglected, it can also lead to the abandonment of all previous efforts. Therefore, BYD needs to make more efforts in product line quality control and ex-factory quality inspection.
