    Abstract: Provided are a battery management system and a battery management method. The battery management system includes a sensing unit to generate a sensing signal indicating a voltage and a current of a battery, a memory unit to store a reference charging map for constant-current charging using first to mth reference C-rates, and a control unit to determine a start value indicating a charge factor at a time point at which a charge command is received based on the sensing signal. The control unit generates first to mth reference charge functions corresponding to the first to mth reference C-rates in a one-to-one relationship from the reference charging map. When a charge cycle starts, the control unit controls a charge current supplied to the battery using the first to mth reference C-rates in a sequential order based on the sensing signal, the start value and the first to mth reference charge functions.
