Recently, there have been a number of new energy vehicle fires in many places in China.

On June 6th, a car blogger announced that a BYD Tang new energy car caught fire on the road. The video shows smoke rising from the chassis of a new energy vehicle parked in the middle of a slippery road, then traffic police took out a dry powder fire extinguisher to put out the fire, and the vehicle crackled and exploded several times during the fire-fighting process. Subsequently, the fire of the vehicle suddenly increased and soon covered the vehicle. As of press time, the brand concerned has not responded to the fire accident, and the cause of the accident has yet to be investigated and notified.

According to the regulations on the recall of defective Automobile products and the measures for the implementation of the regulations on the recall of defective Automobile products, BYD Automotive Industry Co., Ltd. filed the recall plan with the State Administration of Market Supervision and Administration, and decided to recall 9663 Tang DM models produced from September 2, 2021 to March 14, 2022. The announcement shows that due to manufacturing reasons, the installation surface of the tray breather valve of some vehicles within the scope of the recall is uneven, and there is a risk of water intake, which may cause electrical circuit failure of the power battery system, and in extreme cases, there is a risk of thermal runaway of the power battery. In view of the above defects, BYD Automotive Industry Co., Ltd. will entrust an authorized dealer to inspect the vehicles within the recall scope, and replace the battery pack free of charge if there is leakage of the battery pack or uneven installation surface of the pallet breathable valve. To eliminate safety risks. It is also unknown whether the accident is related to the above recall.

In addition, a new energy vehicle also caught fire at the exit of a tunnel in Nanhai District of Foshan, Guangdong Province on June 6, according to the Foshan Xiaoqiang hotline. Judging from the release of the video, the fire at the scene was fierce and thick smoke billowed, but the fire location of the new energy vehicle seemed to be in the carriage, and the fire in the chassis position was obviously weaker than that in the car, and then firefighters arrived at the scene to put out the fire, but the whole vehicle was basically scrapped. At present, the relevant brands have not responded to the fire accident, and the automobile industry will continue to pay attention to it.

Under the background of the continuous popularity of new energy vehicles, the fire incident has also become a hot topic of social concern. Some netizens believe that as an emerging industry, some actions of new energy vehicles will be infinitely magnified by the outside world, and the fire incident has become the focus of network attention. Some netizens also believe that there are many reasons for the fire of new energy vehicles. New energy vehicles are mainly driven by power batteries, and the current and voltage are relatively large, which to a certain extent increases the possibility of causing vehicle fire.

Xin Guobin, vice minister of the Ministry of Industry and Information Technology, once said that the battery is actually a very fragile component. In addition to the single battery, there is also a problem with the management of the battery pack, which requires high technical requirements, and it also needs timely maintenance and testing in the course of use. Otherwise, there is a greater risk in the charging process and an hour after charging. Once the thermal control management is not good, deflagration may occur. Even with this problem, the spontaneous combustion rate of new energy vehicles is still lower than that of traditional cars. Centralized management by the battery operator can improve the safety of the battery.
