Lithium battery protection chip, as the name implies, is designed to protect the safety of the battery, that is, to prevent the battery from overcharging and exploding and to prevent the battery from being easily damaged due to overdischarge. The lithium battery protection board is a protection circuit installed at the negative terminal of the battery. Its main function is to prevent overcharging from damaging the battery cell, over-discharge damaging the battery cell, and overcurrent damaging the battery cell.
In these three main functions, if the selected lithium battery does not have a battery protection board, overcharging can be avoided by the charger protection circuit, and overcurrent is not something we need to worry about if the quality of the cell is too high.
Lithium batteries require the protection of charging overvoltage, discharge undervoltage, overcurrent, and short circuit. During the charging process, the problem of balanced charging of the entire group of batteries is introduced. A single-cell lithium battery protection chip is introduced for any number of groups connected in series. The design scheme of the battery pack protection board with equalizing charging function to protect the lithium battery.
