How to prevent battery fire in pure electric vehicles?

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?

1. 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.

1. 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.

1. 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.

1. 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.

应当如何预防纯电动汽车电池起火？

纯电动汽车电池起火，主要有两个方面原因：充电起火和非充电起火。一般在快充模式下，由于是大电流充电，导致过流、过充和过热等情况的发生，如果此时BMS电池管理系统管控不力的话，就可能导致起火的发生。所以，平时在充电过程中，一定要选择智能充电桩进行安装，同时要定期进行电池保养和检测，如果发现存在异常，就需要立即到正规维修服务网点进行维修处理。

非充电起火，很常见的一个场景就是底盘被磕碰之后，动力电池包被撞倒，或者纯电动汽车发生交通事故被撞击之后，动力电池包受损，也是有可能导致电池起火的。如果发生底盘磕碰之后，还是需要立即到正规4S电进行检查。

如果再做好预防措施之后，依然发生的起火事件，大家也不要恐慌，应该要沉着冷静处理。如果发现电动汽车起火，如果车上有灭火装置，就可以考虑自行灭火，如果确实无法扑灭，就需要远离电动汽车。

新能源汽车起火事件频发，那么对于车主来说应当如何预防呢？

1.定期维护保养

和传统燃油车一样，新能源汽车在后期使用过程中也需要定期进行维护保养，尤其是对动力电池的检测以及线路的检查，这样可以提前排查安全隐患，降低起火的发生率。

2.养成良好的充电习惯

纯电动汽车能量补充方式一般依靠的是充电桩，但是在使用充电桩进行充电时，避免充电时间较长，尤其是高温条件下充电，控制充电时间。因为对于动力电池来说，充电其实就是内部的化学反应过程。长时间充电，化学反应越发剧烈，就会导致电池温度上升，从而容易发生热失控现象。

3.改装要留意

虽然对新能源汽车改装的朋友较少，但是也不乏有改装的存在。对于汽车的改装，很多情况下都会涉及到线路，而部分改装店施工不当，导致线路出现短路，就会加大起火的可能性。

4.安全驾驶很重要

在行驶过程中因碰撞发生起火的现象也较多。因为碰撞会导致电池变形，线路很容易出现短路，这时候电池的温度会快速上升，从而导致起火甚至爆炸。

要预防新能源汽车起火的出现，车主需要养成良好的用车习惯和安全驾驶习惯。除此之外，作为车企和电池企业来说，需要提高动力电池的稳定性和防护能力，这样多管齐下才能够更好的避免起火的发生
