ABSTRACT:
A Battery Management System (BMS) and a battery management method include a sensing unit to measure a battery terminal voltage, current, and temperature, and a Main Control Unit (MCU) to compare the measured battery terminal voltage, current, and temperature to a State of Charge (SOC) reset condition and to reset a battery estimate SOC according to the comparison result. The MCU resets the battery estimate SOC to a first reset SOC when the SOC reset condition corresponds to a first SOC and reset the battery estimate SOC at a second reset SOC when the SOC reset condition corresponds to a second SOC.
