Previously, Xi'an Feihu ES8 self-ignition event triggered a multi-party concern, once again pushed the battery safety problem of pure electric vehicles to the tip. Recently, the official announcement of the car is officially announced, and this self-ignition accident will be described. According to the exemption of the car, the accident vehicle has been severely impacted due to the previous chassis, causing a large area of ​​the left rear outer casing of the power lithium battery pack to deformed the cooling plate, after a period of time, short circuit, but because the hit did not pierce the battery pack The base plate, so the vehicle failed to monitor the leakage and insulation of the coolant, and did not appear abnormal data in the battery, and did not take the gantry monitoring when the car was maintained.

So eventually triggered a fire. That is, the fire of this ES8 is because it has been seriously impacted. In order to further protect the safety of the power lithium battery, it is recently released the "Method of Further Supporting the Safety of Lithium Battery", including five measures: 1.

Strengthen emergency response and mechanism: If the vehicle is in driving The chassis collisions, or has happened, the owner contacts the car hotline, and the staff will go to the site to check the vehicle; 2, add the newly testing of the battery pack bottom plate: Except for the bottom of the existing battery pack From now on, as long as the vehicle is maintained or maintained, it will add a separate work item of the vehicle lifting inspection battery pack; 3. Increase the inspection of the battery pack when the power transmission and one-click power supply service: current vehicle When the station exchanges electricity, the staff will manually check the bottom plate of the vehicle battery pack, and comprehensive inspection of other electrical properties of the battery. Since then, the car will further strengthen the battery pack inspection process in the power-exchanged and one-click power-saving service, and add the necessary technical assistance means.

4, free to replace the battery pack with safety hazards: If the vehicle battery pack has been hit, it is found that there is a safety hazard, and the car will replace the same specification for free of the vehicle free of charge, and scrapped the battery pack. solve. 5.

Carry out fire drills, strengthen security awareness: Jewa will strengthen employee fire safety awareness and emergency disposal ability. At the same time, it will also cooperate with fire and rescue units to do a good job in emergency disposal ability. In addition, it is also an urgent consumers to pay attention to consumers.

If the battery is abnormal, please leave the vehicle immediately. Four doors quickly launched two downwards. When the security door lock is started, the rear door should be opened from the outside).

If the battery is smoked, the fire is safe after ensuring the safety of the person. Since the battery is anoxic burning, only a large amount of water temperature can be flame retardant, and the general dry powder or foam fire extinguisher cannot prevent battery combustion. From the emergency mechanism to a free replacement of the battery pack, it can see that the awareness is still quite responsible, and further protects the personal and property safety of consumers.

However, the problem of electric car battery is not processed from the root cause, and such hidden dangers still exists, and will become a concern of many consumers to buy new energy vehicles with electric vehicles. one. .
