BMS is also called a battery management system. Its main function is to intelligently manage and maintain each battery unit, prevent overcharging and over-discharging of the battery, extend the battery life, and monitor the battery status.

The BMS lithium battery management system determines the status of the entire battery system by detecting the status of each single battery in the power battery pack, and makes corresponding control adjustments and strategy implementations for the power battery system according to their status, so as to achieve charge and discharge management of the power lithium battery system and each single battery to ensure the safe and stable operation of the power battery system.

The five common parts of BMS include battery monitoring and protection, battery management and control, charge and discharge power path, communication and sensing, and auxiliary power supply.
