What is the protective plate of lithium battery of balance car?

Lithium batteries for balancing vehicles are generally equipped with protective plates. The protection board is a circuit protection device, which aims to ensure the safety of lithium batteries. It mainly has the following functions:

1. Overcharge protection: When the voltage of the lithium battery exceeds the set safe voltage, the protection board can automatically cut off the connection between the battery and the external circuit to prevent the battery from being overcharged and reduce the safety risk.

2. Overdischarge protection: When the voltage of the lithium battery is lower than the set safe voltage, the protection plate can isolate the battery from the external circuit, so as to prevent the battery from overdischarge and improve the battery life.

3. Overcurrent protection: When the current in the external circuit exceeds the safe current set by the protection board, the protection board will cut off the connection between the battery and the external circuit to prevent the battery from being overloaded and protect the battery.

4. Short-circuit protection: When there is a short circuit between the anode and cathode of the battery, the protection board will immediately cut off the connection between the battery and the external circuit to avoid fire and other dangerous situations.

Therefore, installing protective plates can effectively ensure the safety of lithium batteries in use and prevent accidents caused by overcharge, overdischarge, overcurrent and short circuit.
