Don't panic if a lithium-ion battery pack catches fire. Remember to fix it
A fire on a lithium-ion battery pack is rare, but it can cause a lot of buzz and publicity. Whether it's an energy storage plant or an electric bicycle, the battery may have caught fire because of an internal fault rather than the battery itself. The main reason is that the heat is out of control. To know how to put out the fire, you have to know the cause of the battery failure.
Why do lithium-ion batteries catch fire?
The main cause of ignition of lithium battery is that the heat in the battery is not released according to the design requirements, which will cause the fire after reaching the ignition point of internal and external combustion materials. The main reasons include external short circuit, external high temperature and internal short circuit. I won't go into details.
Two, how should the lithium-ion battery pack fire?
After fully understanding the cause of lithium battery fire, it is necessary to mention what we should do to put out the fire after the fire, the following four methods are listed, we will understand one by one
1. It is only a small fire, and the high-pressure battery is not affected by the flame. Carbon dioxide or dry powder fire extinguisher can be used to extinguish the fire.
2. If the high-voltage battery is distorted or seriously deformed in a serious fire, there may be a problem with the battery. Then we have to take out a lot of water to put out the fire, it has to be a lot of water
3. When checking the specific situation of fire, do not contact with any high-voltage components, and be sure to check the whole process with insulation tools.
Be patient when putting out a fire. It may take a whole day. A thermal imaging camera would be useful if it were available. Thermal camera surveillance would ensure that the high-voltage battery would be fully cooled before the accident was over. Without this condition, the battery is monitored until the lithium-ion battery pack is no longer hot. Make sure that at least an hour later there is still no problem. It takes a lot of time and effort to put out a fire and make sure it doesn't happen again, but you don't have to worry about that, because lithium batteries are not explosive, you don't have to worry about that.
