I believe everyone is familiar with lithium batteries! With the promotion of green travel, recyclable and environmentally friendly batteries—lithium batteries—have been widely used in various fields. Compared to batteries made of other materials, lithium batteries are lighter, have higher safety performance, and have a higher number of cycles. However, if used improperly, these products can still cause safety accidents, with lithium battery fires being a common battery malfunction. So what should we do when a lithium battery catches fire? Next, let'sElectric vehicle battery connecting piecesThe manufacturer will give you a detailed introduction!

Lithium-ion battery fires can cause intense reactions and extensive exposure. Whether it is a storage station or an electric bicycle, the cause of the battery fire may be an internal battery fault rather than the battery itself. The main reason is temperature runaway. To know how to put out the fire, you must understand what caused the battery failure.

The main reason for lithium battery fires is that the heat in the battery is not released according to design requirements. Fires occur after reaching the ignition point of internal and external combustible materials, with the main causes being external short circuits, external high temperatures, and internal short circuits.

How to deal with fire extinguishing issues of lithium-ion batteries?

After fully understanding the causes of lithium battery fires, we should propose suggestions on how to extinguish the fire afterward. There are four methods.

1. Only one small ignition source is installed. High-voltage batteries are not affected by flames; carbon dioxide or dry powder extinguishers can be used to extinguish the fire.

2. If the high-voltage battery deforms or severely deforms during a severe fire, the battery may malfunction, then we must release a large amount of water for firefighting; a lot of water is definitely required.

3. When inspecting the specific situation of the fire, do not touch any high-voltage components, and be sure to use insulated tools for overall inspection.

4. Be patient when extinguishing the fire; it may take a whole day. If there is a thermal imaging camera, it can be used. The thermal imaging camera can be monitored to ensure that the high-voltage battery is completely cooled before the incident ends. If this is not the case, the battery should be monitored throughout until the lithium battery pack no longer generates heat, ensuring that there are no issues for at least one hour afterward. We need a lot of time and effort to make sure it doesn't happen again, but don't worry too much about the lithium battery exploding; generally, such a large accident will not occur.

The above are the specific methods for dealing with lithium battery fires introduced by the editor. I hope that after reading this, it can provide some help to everyone!In order to prevent lithium batteries from causing fires due to improper use, everyone must charge according to regulations. This not only ensures personal safety and property security but also provides a better travel experience!
