A battery management apparatus according to the present disclosure includes a memory to store a charging sequence table that records a correspondence relationship between first to mth temperature ranges, first to mth SOC lists and first to mth current lists, a sensing unit to detect a voltage, a current and a temperature of a battery, and a control unit. Each of the SOC lists defines first to nth SOC ranges. The control unit determines a current SOC of the battery based on the detected voltage and the detected current. The control unit determines a temperature range of interest, a SOC list of interest and a current list of interest based on the detected temperature. The control unit determines a remaining charging time required to charge the battery to a target SOC based on the detected current, the current SOC, the SOC list of interest and the current list of interest.
