What should I do if the lithium battery pack catches fire?

From:CTECHI GROUP Limited     Release time:2019-11-06

Overview:Lithium-ion battery ignition is a very unusual situation, but when it happens, it causes a strong reaction and a lot of exposure. Whether it is a storage station or an electric bicycle, the cause of the battery fire may be internal battery failure, not the battery itself. The main reason is that the temperature is out of control. To know how to put out a fire, you must know what caused the battery to malfunction.

Lithium-ion battery ignition is a very unusual situation, but when it happens, it causes a strong reaction and a lot of exposure. Whether it is a storage station or an electric bicycle, the cause of the battery fire may be internal battery failure, not the battery itself. The main reason is that the temperature is out of control. To know how to put out a fire, you must know what caused the battery to malfunction.

The main reason for the ignition of lithium batteries is that the heat in the battery is not released according to the design requirements, and the fire occurs after the ignition point of the internal and external combustion materials is reached. The main causes are external short circuits, external high temperatures and internal short circuits.

How to deal with the ignition problem of lithium ion batteries?

After fully understanding the cause of the fire on the lithium battery, we should suggest how to extinguish the fire after the fire. There are four ways

1. Only one small fire was installed. High voltage batteries are not affected by the flame. Carbon dioxide or dry powder fire extinguishers can be used to extinguish fires.

2. If the high voltage battery is deformed or severely deformed in a serious fire, the battery may be faulty. Then we have to release a lot of water to put out the fire. There must be a lot of water.

3. When inspecting the fire, do not touch any high voltage parts. Always use an insulated tool for overall inspection.

4. Be patient when extinguishing fire. It may take a whole day. If you have a thermal imaging camera, you can use it. The thermal imaging camera can be monitored to ensure that the high voltage battery is completely cooled before the end of the accident. If this is not the case, the battery should be monitored throughout the process until the lithium-ion battery pack no longer heats up. Make sure there is no problem after at least an hour. We need a lot of time and effort to make sure it doesn't happen again, but don't worry too much. Lithium batteries will not explode. Generally speaking, such a big accident will not happen.
