ZTE High Energy provided 2257 units of Weimar Motors with batteries, while the latter only announced the recall of 1282 units

On October 29, ZTE High Energy announced that the two Weimar auto-ignition accidents in Fujian were caused by the company providing batteries, but the explosion of the Beijing Weimar auto battery on the 27th was not a high-energy battery.

Weimar electric vehicles have experienced spontaneous combustion accidents in the past 40 days, and on October 28, it announced the recall of 1,282 hidden vehicles.

However, ZTE High Energy has installed more than 1282 batteries for Weimar Automobile, and the remaining vehicles have not appeared on the recall list.

It is reported that since Weimar Motors launched mass production vehicles, there have been 7 battery suppliers, namely, CATL, Tianjin Lishen, Jiangsu Tafeier, Suzhou Yuliang, Zhejiang Gushen, ZTE High Energy and Ruipu Energy.

The recalled models are equipped with ZNP3914895A-75A batteries, which are NCM523 batteries produced by ZTE High Energy.

In the first three quarters of 2020, Weimar Motors built 15,700 vehicles and adopted 4 battery suppliers, including 9,692 units from CATL (61%), 3313 units from Tafel (21%), and 2,257 (accounting for 14%), Ruipu Energy 532 units (accounting for 4%).

We have noticed that, including the accident model, ZTE High Energy provided a total of 2,257 batteries for Weimar.

After two spontaneous combustion in Fujian on October 5 and 13, and an explosion in Beijing on October 27, Weimar Motors admitted that the model’s ZNP3914895A-75A batteries had hidden dangers and announced the recall of 1282 units the next day. In other words, the remaining 975 units are not involved in the recall.

Weimar Motors explained the explosion in the announcement: "After technical analysis and repeated verification, this incident was caused by the battery cell supplier mixing impurities in the production process, which caused abnormal lithium evolution in the power battery, and in extreme cases may cause the battery cell to short circuit. , Causing power battery thermal runaway and risk of fire, posing safety hazards."

If this is the case, then it can be concluded that among the batteries provided by ZTE High Energy, only some of the cells have encountered "impurity" problems, not all of them.

However, is there no hidden danger in the ZTE high-energy battery used in 975 cars? Weimar has not responded directly to this.
