Lithium Battery Protection BMS PCB Board 0.065mm HASL Surface Finishing

1. The reason why the lithium-ion battery needs to be protected is determined by its own characteristics. Since the material of the lithium-ion battery itself determines that it cannot be overcharged, over-discharged, overcurrent, short-circuited and ultra-high temperature charge and discharge, the lithium-ion battery components will always appear with a delicate protection board and a current fuse.
2. The BMS protection function of the lithium-ion battery is usually completed by the protection circuit board and current devices such as PTC. The protection board is composed of electronic circuits, which can accurately monitor the voltage and The current of the charging and discharging circuit can control the on-off of the current circuit in time; PTC can prevent the battery from being badly damaged in a high-temperature environment.
