In October of this year, with the successive fires of Weimar Motors, the most sensitive battery safety issue of electric vehicles was brought to the forefront.

On October 28, the State Administration for Market Regulation issued an announcement on the recall of 1282 Weimar cars. Weimar Motors officials also publicly acknowledged the battery problem for the first time and pointed the cause of the two spontaneous combustion accidents that occurred earlier this month to battery supply. The manufacturer stated that the reason for the recall was that the battery supplier mixed impurities during the production process, which caused the battery to have a fire risk.

The battery supplier who provided this type of battery cell became the party directly responsible for the fire in Weimar Motors. The “ZNP3914895A-75A model battery” exposed in this announcement has also become the focus of attention.

Weimar Motors stated to Future Auto Daily (ID: auto-time) that the reason for recalling the Weimar Motors equipped with battery model ZNP3914895A-75A produced from June 8 to September 23 this year is that Because of the two spontaneous combustion incidents that occurred on October 5 and 13, the accident vehicle was equipped with this battery.

On the evening of October 28, ZTE High Energy issued an announcement acknowledging that the batteries on the two spontaneous combustion vehicles on October 5 and 13 were provided by ZTE High Energy, but at the same time emphasized that the Weimar Group that caught fire in Beijing on October 27 EX5, the vehicle involved is not equipped with high-energy technology batteries.

On the evening of October 27, a Weimar electric car caught fire and exploded in the Beijing North Fourth Ring Institute of Mechanics. An eyewitness at the World Science and Trade Building at a crossroad from the place of the incident told Future Auto Daily (ID: auto-time), “The windows of the 20th storey were all shaken. After half an hour, you can still smell the same The smell of burnt rubber.”

ZTE High Energy is a wholly-owned subsidiary of ZTE Corporation’s new energy sector. Industry insiders told Future Auto Daily (ID: auto-time) that among China’s battery suppliers, ZTE High Energy belongs to the third echelon compared to BYD, Ningde Times, Guoxuan Hi-Tech, and AVIC Lithium. According to data from the Advanced Industry Research Institute (GGII), the company has provided a total of 2,046 Weimar vehicles in the second quarter of this year.

Among them, Tianjin Lishen Battery Co., Ltd. was established in 1997 with a registered capital of 1.25 billion yuan. It is one of the long-term battery suppliers of Weimar Motors.

At present, the cause of the vehicle fire has not been ascertained. As early as September last year, Wang Zidong, deputy secretary-general of the China Automotive Power Battery Industry Innovation Alliance, expressed concern, “When everyone analyzes the electric car on fire, no one can tell exactly what the problem is. Because the accident was destroyed after the burn. At the scene, no valuable data can be found, and it is difficult to find the cause of the accident.”

He believes that in order to solve safety issues, improvements are needed in terms of material matching, battery module structure, battery system integration, and charging methods.

The fire incident also caused concerns among other car owners. A Weimaran owner involved in the recalled vehicles told Future Auto Daily (ID: auto-time) that on October 17th, shortly after picking up the car, Weimaran received an “accident alert” as the excuse that the vehicle needs to be overhauled. Notice of recall.

“The staff did not mention about the spontaneous combustion of the car.” The above-mentioned car owner said that after checking social media, he learned that the car has a hidden danger of spontaneous combustion.
