What is a battery protection board?

by:CTECHi     2021-08-18

The battery protection board is an integrated circuit board that protects rechargeable batteries (usually lithium batteries). Due to the materials used to make lithium batteries, they cannot be overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charged and discharged, so the necessity of battery protection boards has emerged. The battery protection board can instantly control the on and off of the current loop to prevent severe damage to the battery. It is used to protect the battery from damage and prolong the service life of the battery. And it only provides the most stable and effective protection to prevent accidents in the event of extreme battery problems. Normally it should not be activated. Of course, monitoring is necessary, just like the fuse or safety switch in our household appliances.
