SMM7, July 7: July 5 afternoon, Wuhan Hongshan District, a new energy vehicle charging station, a Geely electric vehicle suddenly came out of smoke, smoke mainly from below the rear of the vehicle, there was no open fire at the scene. After receiving the alarm, two fire engines and 12 firefighters from the Hongshan South Lake Fire Squadron rushed to the scene. At this time, the ground under the vehicle had been blackened, and firefighters immediately used water to cool the vehicle.
Until the factory technical personnel arrive at the scene, in order to prevent the vehicle from burning or reburning, it is planned to disassemble the power battery at the bottom of the vehicle. Under the joint efforts of firefighters and others, the smoking Geely electric vehicle was turned over and the power battery at the bottom of the vehicle was dismantled under the guidance of technicians. Subsequently, firefighters once again used dry powder fire extinguishers to cover it to eliminate hidden dangers.
According to the notice issued by the Ministry of Industry and Information Technology in June on the investigation of potential safety risks of new energy vehicles, all vehicle enterprises should promptly carry out accident investigation after the fire and combustion accident of their new energy vehicles, and report the basic information of the accident within 12 hours, and report the detailed information of the accident within 48 hours, and take the initiative to report to the lead department and equipment center of the joint meeting of new energy vehicles.
Recently, Mr. Xin Guobin, member of the leading Party Group of the Ministry of Industry and Information Technology and Vice Minister of Industry and Information Technology, delivered a keynote speech at the 2019 World New Energy vehicle Congress. Xin Guobin gave a brief introduction to the recent widespread concern in the new energy vehicle industry about the safety of new energy vehicles. In view of the recent frequent fire accidents of new energy vehicles, the Ministry of Industry and Information Technology has resolutely taken effective measures. On the one hand, from the aspects of R & D, production and fire protection, we will speed up the improvement of a comprehensive and effective safety guarantee system, and further implement the main responsibilities of the industry departments. Curb the occurrence of fire accidents in new energy vehicles. On the other hand, the Ministry of Industry and Information Technology has organized the preparation of electric vehicle safety guidelines, launched a new energy vehicle safety initiative, carried out a series of actions such as how to safely use electric vehicles to promote science popularization, so as to reduce the safety risk of new energy vehicles and create a good social environment.
Earlier, there were a number of spontaneous combustion and smoke accidents in Weilai cars. A few days ago, Weilai Automobile Co., Ltd. was commissioned to file the recall plan with the State Administration of Market Supervision and Administration in accordance with the requirements of the regulations on the Administration of recall of defective Automobile products and the measures for the implementation of the regulations on the Administration of recall of defective Automobile products. Since June 27, 2019, the recall section has carried a total of 4803 Weilai ES8 electric vehicles with power battery packs produced between April 2, 2018 and October 19, 2018. After investigation, it is found that because the voltage sampling wire harness in the battery package module is squeezed by the cover plate, the risk of short circuit of low voltage sampling wire harness may occur under some extreme conditions, and there is a hidden danger of safety.
At present, the development of lithium battery is a major trend, but with the rapid development, we should fully consider the safety of the use of power battery and formulate relevant control measures.
