A battery management system according to the present disclosure 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 first to nth reference currents (n is a natural number of 2 or greater), first to nth reference voltage ranges, first to nth reference states of charge (SOCs) and first to nth reference voltage curves for multi-stage constant-current charging, and a control unit to command constant-current charging using a kth reference current (k is a natural number of n or smaller) corresponding to a kth reference voltage range to which the battery voltage belongs to a charging circuit in response to a charge start command. The control unit updates the charge map by comparing a kth measured voltage curve indicating a correlation between the battery voltage and the SOC of the battery over a charging period of the constant-current charging with a kth reference voltage curve in response to the battery voltage having reached an upper limit of the kth reference voltage range.
