Abstract
A battery management system includes a sensing unit to generate a sensing signal indicating a battery voltage and a battery current of a battery, a memory unit to store a charge map recording a correlation between first to nreference state of charge (SOC) ranges, first to nreference currents and first to nreference voltages for multi-stage constant-current charging, and a control unit to change to constant voltage charging using a kreference voltage corresponding to a kreference SOC range in response to the battery voltage having reached the kreference voltage during constant current charging using a kreference current corresponding to the kreference SOC range to which an SOC of the battery belongs. The control unit updates the kreference current of the charge map based on a time-series of the battery current in a charging period of the constant voltage charging.
