Smart Lithium Battery BMS

The smart lithium battery BMS is internally divided into two parts, BMU and BDC.

BMU (Battery Management Unit) realizes the voltage and temperature monitoring of single cells, SOC calculation, operation logic strategy control, parameter setting, external communication and other functions.

BDC (Bidirectional Direct Current Converter) is a bidirectional current conversion circuit between the battery pack and the main circuit of the communication backup power supply.

Features

It is used to perform battery constant current, constant voltage charging and discharging, standby, and protection functions.
