The reasons for many lithium battery combustion incidents are as follows:
1. The battery is getting old. If a set of large batteries has been used for a long time, there will definitely be a broken cell inside. If the electric vehicle BMS cannot detect the broken cell, it will slowly destroy all cells. if it breaks, it could possibly cause a fire.
2. The internal resistance of the battery is too large, false soldering during the manufacturing process, the metal conductor is too small, etc. The internal resistance of the battery is too great, causing heat and fire.
3. The battery is swollen and leaking, which can easily cause a fire
4.
