Everyone is familiar with the lithium battery protection board, but how many people know how it came from? Why did you come here? Today, the Chinese Chuangfa will take a look at the origin of the lithium battery protection board with everyone.

Lithium batteries (rechargeable) need protection because of their own characteristics. Because the material of the lithium battery determines that it cannot be overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charging and discharging, the lithium battery components of the lithium battery will always appear with an exquisite protection board and a current fuse. The protection function of lithium 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 of the battery cell and the current of the charging and discharging circuit in an environment of -40 degrees to 85 degrees. , Control the short-circuit of the current loop in time, PTC prevents the current from severe damage under high temperature environment.
