The LBC is the core of battery control. It detects the battery pack voltage and current, temperature inside the battery and intake temperature, and the voltage of each cell to determine the SOC (state of charge). It also calculates the allowable input/output values, and transmits the calculation data to the HPCM (Hybrid power train control module). The HPCM controls the vehicle according to the battery status.
