Weilai will take temporary measures to limit the charging capacity to 90%

After the ES8 spontaneous combustion incident at the Xi’an service station, a Weilai ES8 near Anli Road, Jiading District, Shanghai suddenly smoked again on May 16. As the cause of the accident has not been ascertained, on the evening of May 17, Wei Shen Fei, vice president of Lai Auto Energy, published 'Temporary Measures for Strengthening Charging Safety' on the Weilai APP, stating that the accident vehicle was parked for 4 days with the gun inserted, and the system automatically recharged after being fully charged to keep the battery full for a long time. Electricity status. In view of the fact that the failure probability of the power battery will increase in the state of high power for a long time, out of the principle of safety and prudence, before the official investigation results come out, Weilai will take temporary measures for the exclusive piles and vehicles in the connected state Limit the charge to 90%. This has caused many Weilai ES8 users to express dissatisfaction on the APP side. After limiting the charging capacity to 90%, the cruising range will be shortened accordingly. Shen Fei further responded that this is only a temporary measure, because the pile end is changed quickly, and the software will be upgraded later, and the user chooses how much to charge. In the next step, on the mobile app, everyone can choose whether to travel daily or to travel long distances with full battery. It is expected to be released next week. This temporary measure will affect at most one week. Shen Fei also said that for charging in a non-networked state or when using a third-party charging pile, unless it is really necessary, it is also recommended that car owners charge less than 90% of the electricity in daily use. 'The above measures do not mean that the accident was caused by charging. At present, the cause of the accident is still under investigation. We will notify you after we have a preliminary conclusion.' Industry insiders analyzed that Weilai’s response was due to the battery 'Safety' considerations. Generally, during the charging process, the battery cannot be charged too full, and the battery cannot be put into space. If it is fully discharged every time, its service life will be greatly reduced. In addition, if the charging is too full, once the charging system fails, it may cause a safety accident due to 'overcharging'. On May 16, a Weilai ES8 suddenly smoked in the underground garage of a residential area near Weilai's headquarters. Weilai said that the fire officers and soldiers rushed to the scene to extinguish the smoke in time, and there were no injuries or other property losses at the scene. The cause of the smoke in the vehicle is currently unknown. Weilai has initiated an investigation and will make an announcement in time after the cause is identified. It is reported that in the incident, no other vehicles were affected by the fire, and no casualties were caused. The cause of the accident is under further investigation. Li Bin, the founder and chairman of Weilai Automobile, responded to the entire incident reviewed by the car owner on the Weilai APP, 'Thank you for sharing the details of the incident. I am sorry that you and your husband are worried and sad. We will investigate the cause in detail. 'Qin Lihong, co-founder and president of Weilai Automobile, also apologized to the owner's experience on the Weilai APP and said that he would analyze the cause of the accident in depth, 'to give you and other users peace of mind. The owner is rational, and Weilai is serious. There is no hurdle to pass, it is an opportunity to deal with it.” This is the second time that Weilai has had a spontaneous combustion accident in a month. On April 22, a Weilai ES8 under repair at the Xi’an Weilai authorized service center experienced spontaneous combustion. event. After investigation, the official reason given by Weilai was that “the chassis of the vehicle had been severely impacted before being sent for repair, which caused large-area deformation of the left rear shell and cooling plate of the power battery pack. The internal structure of the battery pack was being squeezed. After a period of time in the state, a short circuit was formed, which eventually caused a fire.' After the spontaneous combustion incident, Weilai officially released measures to further protect the safety of the power battery of the user’s vehicle, and strengthen the inspection of the battery pack bottom plate during the battery swap and one-click power-on service. When the vehicle enters the station to change the battery, the Weilai staff will Manually inspect the bottom plate of the vehicle battery pack, and conduct a comprehensive inspection of the battery and other electrical properties. In addition, NIO will also replace battery packs with potential safety hazards for car owners free of charge. If the battery pack has been hit and found to have safety hazards after inspection, NIO will replace the battery packs of the same specification for car owners free of charge. If an emergency occurs due to abnormal battery function, please leave the vehicle immediately. If you find that the battery is smoking or catching fire, please report to fire alarm 119 after ensuring the safety of the personnel, and spray a large amount of water on the damaged location.
