1. There is a problem with the quality of the battery itself, and the pile head is hidden with a polar plate.
2, the battery has cracks in the transportation or installation without timely discovery, and the internal acid liquid in the battery reacting the battery or the battery cabinet is chemically reacted until the battery holder or the battery cabinet is chemically reacted.
3, the battery and the cable are connected to the cable, which causes too much contact resistance. The contact surface is severely oxidized, thereby causing the contact resistance to become large, and will eventually cause electrical fire and even scull, and finally ignite nearby flammable products .
4. The pressure resistance value of the battery pack is not enough, resulting in insulated breakdown between the cables to cause the cable short circuit.
5, the battery configuration is unreasonable, beyond the battery discharge limit.
6. Battery connection cable is short-circuited by a battery cabinet by a battery cabinet.
7, the UPS host charging current is too large or the voltage is too high.
8, the external connection cable or internal connection cable of the battery pack is due to the use of time for the use of time for the expansion, and there is no timely checking to generate a short circuit to generate a short circuit between the cable and the battery cabinet.
