[YesAuto News] At around 11:03 am on August 11, a white Xiaopeng car G3 had a smoke and fire accident in the Pazhou Science and Technology Building, Haizhu District, Guangzhou. From the video circulating on the Internet, it can be seen that the fire was in progress. There was also a sound of a suspected explosion, and the scene was full of smoke, and the fire was extinguished by firefighters who arrived later.
In response to this matter, the car home contacted the staff of Xiaopeng Motors, the official said: the occupants are safe, no one was injured, and the vehicle has been quickly and safely transferred. After preliminary investigation by Xiaopeng Motors staff, the appearance of the vehicle was intact. After lifting and surveying at the store, it was found that there were obvious and serious bumps on the bottom of the battery box, which caused severe damage to the battery. The preliminary judgment is the cause of the accident. The company will conduct further detailed investigation and analysis of the accident.
Just in June of this year, Xiaopeng Motors just applied to the State Intellectual Property Office for a patent on the protection method for thermal runaway of electric vehicles. When a thermal runaway occurs in the vehicle, the fire extinguishing device in the car can automatically sense and extinguish the power battery assembly. Work, thereby reducing the risk of vehicle explosions.
Xiaopeng Motors has not disclosed when this patent will enter the mass production stage. According to the patent content, this technology may play an important role in protecting the battery safety under the condition of thermal runaway of the vehicle. However, the battery damage caused by the collision may occur this time. Not within the scope of patented technology, it can be seen that the road to electric vehicle battery safety is obstructed and long.
As early as the end of December 2019, there was a “Xpeng Motors G3 fire accident”, but Xpeng Motors officials later clarified that more burning charcoal and lighters were found at the scene of the accident, and it was judged that the accident was caused by an external fire source. It is not a “spontaneous combustion accident” transmitted on the Internet and has nothing to do with the quality of the battery.
In fact, the reason why every electric vehicle fire accident receives great attention from the media and the public is, in the final analysis, everyone's doubts about the safety of electric vehicles. Obviously, the characteristics of electric vehicles determine that their development process will not be smooth. While improving technical safety, car companies must resolve, investigate, and clarify every fire accident in a timely manner. Consumers' confidence in buying a car depends on every car company to use technology and carefully manage it.
