NIO Responds to ES8 Smoking Incident: Problem Might be “Too Fully Charged Battery”
Current NIO ES8

After the spontaneous combustion of NIO ES8 at Xi’an Service Station, another ES8 near Anli Road, Jiading District, Shanghai, suddenly smoked on May 16th. In the case that the cause of the accident has not been ascertained, on the evening of May 17, Shen Fei, vice president of NIO, released a temporary measure to enhance the security of charge on NIO APP, saying that the accident vehicle was parked for 4 days under the state of charging gun insertion.


“After the battery is fully charged, the system automatically recharges multiple times to keep the battery fully charged for a long time. In view of the fact that the battery will increase its failure probability under the condition of long time and high power.”

Therefore, please don’t connect your mobile phone to the charger all the time, otherwise it will smoke or catch fire:)

Due to the principle of safety and prudence, NIO will temporarily take measures to limit the charge amount to 90% for the exclusive piles and vehicles that are connected to network before the official investigation results.

The burned ES8

This is the second time that NIO has experienced a spontaneous combustion accident. On April 22, a self-ignition incident occurred on a NIO ES8, which is under maintenance at the Xi’an NIO Authorized Service Center. After investigation, the official claimed that “the vehicle had suffered a serious impact before the repair, resulting in a large deformation of the left rear casing and the cooling plate of the power battery pack. The internal structure of the battery pack was squeezed. In the state, after a period of time, a short circuit is formed, which eventually causes a fire.
