BATTERY MANAGEMENT APPARATUS AND METHOD

A battery management apparatus according to an embodiment of the present disclosure includes an inflection point extracting unit configured to extract an inflection point from a battery profile representing a voltage change of a battery over time; and a control unit configured to determine a target voltage, a target temperature, and a target current amount of the battery corresponding to the inflection point, determine a reference voltage corresponding to the target temperature and the target current amount in a preset voltage table, and diagnose whether or not lithium precipitation occurs in the battery based on the reference voltage and the target voltage.
