QT-BMU-48T16D
QT-BMU is the slave part of the battery management system. It monitors the states of the battery pack. The BMU 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 BMU also calculate the SOC/SOH of the batteries.
