There are two main reasons for the fire of pure electric vehicle battery: charging fire and non-charging fire. Generally, in the fast charge mode, due to high current charging, overcurrent, overcharge, and overheating can occur. If the BMS battery management system is not well controlled at this time, it may cause a fire. Therefore, during the charging process, you must choose the smart charging pile for installation. At the same time, the battery must be maintained and tested regularly. If an abnormality is found, you need to go to a regular repair service outlet for repair and treatment immediately.
A non-rechargeable fire, a very common scenario is that the power battery pack is knocked down after the chassis is bumped, or the power battery pack is damaged after a pure electric vehicle is hit in a traffic accident, which may also cause the battery to catch fire. If there is a chassis collision, you still need to go to a regular 4S electrical inspection immediately.
If fires still occur after taking preventive measures, everyone should not panic, and should deal with them calmly. If you find that an electric vehicle is on fire, you can consider extinguishing it yourself if there is a fire extinguishing device on the vehicle. If it is really impossible to extinguish it, you need to stay away from the electric vehicle.
New energy vehicle fires happen frequently, so how should car owners be prevented?
- Regular maintenance
Like traditional fuel vehicles, new energy vehicles also need regular maintenance during later use, especially the inspection of power batteries and line inspections, so that potential safety hazards can be checked in advance and the incidence of fires can be reduced.
- Develop good charging habits
The energy replenishment method of pure electric vehicles generally relies on charging piles. However, when charging piles are used for charging, avoid long charging times, especially charging under high temperature conditions, and control the charging time. Because for power batteries, charging is actually an internal chemical reaction process. Charging for a long time, the more intense the chemical reaction will cause the battery temperature to rise, and thermal runaway will easily occur.
- Pay attention to modification
Although there are few friends who have modified new energy vehicles, there are many modifications. For the refitting of cars, lines are involved in many cases, and improper construction of some refitting shops causes short circuits in the lines and increases the possibility of fire.
- Safe driving is important
There are also more cases of fire caused by collisions during driving. Because the collision will cause the battery to deform, the circuit is prone to short circuit, and the temperature of the battery will rise rapidly at this time, which may cause fire or even explosion.To prevent fires from new energy vehicles, car owners need to develop good car usage and safe driving habits. In addition, as car companies and battery companies, it is necessary to improve the stability and protection of power batteries, so that a multi-pronged approach can better avoid fires.
