According to the news from the General Administration of Market Supervision in China, Shanghai Weilai Automobile Co., Ltd. (NIO) filed a recall plan for its first EV ES8. Since June 27, 2019, a total of 4,803 NIO ES8 electric vehicles equipped with power battery packs from April 2, 2018 to October 19, 2018 will be recalled.
The power battery pack used in the vehicle was equipped with a module of codenamed NEV-P50. The voltage sampling harness in the module may be improperly wounded, which may be squeezed by the upper cover of the module, causing the skin of the extruded voltage sampling harness to wear out. In extreme cases, the insulation of the wire harness may be burnt, causing the battery pack to run out of control and fire, posing a safety hazard. NIO will replace the improved power battery pack for vehicles within the recall range to eliminate potential safety hazards.
