QT-BCU-36T12C
QT-BCU series of products integrate the master function and slave function for the battery management system. It measures the total voltage of the pack, the current, temperature , and voltage of each cell£¬it report alarms or make actions when certain conditions matched such as over voltage, over temperature, under voltage,under temperature etc. The BCU also calculate the SOC/SOH of the batteries, and communication with OBC, MCU and etc.
