What to do if the lithium battery pack catches fire
Lithium-ion battery ignition is a very unusual situation, but when it happens, it can cause 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 the internal failure of the battery, rather than the battery itself. The main reason is that the temperature is out of control. To know how to extinguish a fire, you must know what caused the battery failure.
The main reason for the fire of a lithium battery 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 reasons are external short circuit, external high temperature and internal short circuit.
How to deal with the ignition problem of lithium-ion batteries?
After fully understanding the cause of the lithium battery fire, we should put forward suggestions on how to put out the fire after the fire. There are four ways
1. Only one small tinder is installed. High-voltage batteries are not affected by flames. Carbon dioxide or dry powder fire extinguishers can be used to extinguish fires.
2. If the high-voltage battery is deformed or severely deformed when the fire is severe, the battery may be faulty. Then we must release a lot of water to extinguish the fire. There must be a lot of water.
3. When checking the specific situation of the fire, do not touch any high-voltage components. Be sure to use insulated tools for overall inspection.
4. Be patient when putting out the 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 accident is over. If this is not the case, the battery should be monitored all the way until the lithium-ion battery pack no longer heats up. Make sure there are no problems after at least one hour. We need a lot of time and energy to ensure that it does not happen again, but don’t worry too much. Lithium batteries will not explode. Generally speaking, such a big accident will not happen.
