AutoBeta(AutoBeta.net)06/18 Report--

With the increase of the number of new energy vehicles in the market, the issue of quality and safety has aroused concern again. Recently, there have been a number of cases of spontaneous combustion of new energy vehicles, and consumers have questioned the statement that "electric vehicle fire is a probabilistic event and the fire probability is not higher than that of fuel vehicles." At present, according to the statistics of the network, there were at least three spontaneous combustion accidents of new energy vehicles in June. following the spontaneous combustion of electric vehicles in Lulai, Wuhan, two new energy vehicles occurred spontaneous combustion and explosion.

According to media reports, on June 15, a new energy car exploded and ignited spontaneously while charging at the Auto Expo Center in Chongqing's Liangjiang New District. The car caught fire at the scene, leaving only an iron frame.

According to the video shot by netizens, a number of cars were parked near the spontaneous combustion vehicles, during which someone braved the fire to drive them away.

Subsequently, the Liangjiang New area Fire Rescue Detachment dispatched 24 officers and men from 3 fire engines to fight the fire and eventually put out the fire. The accident caused no casualties and the cause of the fire is under investigation.

Today, netizens revealed that a new energy car caught fire and burst into flames in a logistics park. According to a video provided by netizens, the deflagration accident was very similar to the spontaneous combustion accident of Tesla in Shanghai in April, when a lot of smoke was produced in the position of the vehicle chassis, and then suddenly caught fire and exploded.

From a number of cases of spontaneous combustion of new energy vehicles, it can be seen that once the lithium battery burns, the fire develops very fast, and it is very difficult to put out the fire in a short time, which is a serious and costly accident.

According to the analysis of experts in the field of battery research, the spontaneous combustion fire of new energy vehicles may be caused by the failure of the battery system. "the battery may age because of long-term use, and there is an internal short circuit in the aging process." In this case, the battery will gradually heat up, and when it exceeds a certain temperature range, the battery may catch fire. It may also be because the battery management controller fails and the battery continues to discharge, resulting in battery failure. Experts also point out that if the battery is overcharged, it may also lead to battery failure, which is also a safety risk.

Many netizens expressed concern about the safety of new energy, and said: electric cars are like bombs, parking should be kept away from electric cars in the future.

However, from the point of view of the heads of enterprises engaged in the production and sales of new energy vehicles, they do not think that new energy vehicles are a "threat."

Li Bin, chairman of Xilai Automobile, said in an interview with the media: "Battery spontaneous combustion is only a probability event, and the fire probability of electric vehicles is not higher than that of fuel vehicles." He Xiaopeng, chairman of Xiaopeng Automobile, also said publicly that both electric and hydrogen energy will continue to improve safety, while gasoline is the most unsafe, but everyone is used to it.

Tesla CEO Musk also expressed his views on public opinion, saying, "every year, more than 1 million gasoline vehicles catch fire, resulting in thousands of deaths, but none of them makes headlines like Tesla's car fire. Why should (the media) practice double standards?" The question is so real. "

He also said that Tesla is far less likely to catch fire than gasoline cars: "the reality is that Tesla, like most electric cars, is 500% less likely to catch fire than internal combustion engines, which carry a lot of flammable fuel." why didn't anyone mention that. "

It is believed that there will be another war of words about who is safer, gasoline cars or new energy vehicles.

With the increase of spontaneous combustion accidents, the hidden safety problems of new energy vehicles are becoming more and more prominent. On June 17, the Ministry of Industry and Information Technology issued a notice on the investigation of hidden dangers of new energy vehicles, requiring all automobile companies to carry out the investigation of hidden dangers of new energy vehicles and truthfully report the relevant situation, otherwise the announcements of enterprises and products will be suspended or cancelled. and from the promotion and application of new energy vehicles recommended models and other penalties.

The Ministry of Industry and Information Technology has also given relevant measures for the investigation of fire and combustion accidents of new energy vehicles: enterprises shall bear the first responsibility for the safety of new energy vehicles, and enterprises shall promptly carry out accident investigation in the event of a fire and combustion accident. The production enterprise shall, within 12 hours (if causing death or significant social impact, within 6 hours) the basic information of the accident and the details of the accident within 48 hours. Take the initiative to report to the lead department and equipment center of the new energy vehicle work joint meeting. If there is indeed a product defect, the production enterprise shall take the initiative to file a recall with the competent department.

China is the main battlefield of new energy vehicles in the world, accounting for half of the world's sales. With the rapid development, the hidden dangers of safety can not be ignored in order to promote the healthy development of the industry. A number of spontaneous combustion accidents of new energy vehicles have occurred centrally, and it is hoped that the competent authorities will lead the investigation, and the car companies should also restore the truth of the public accidents.
