BATTERY MANAGEMENT APPARATUS AND OPERATION METHOD THEREFOR

A battery management apparatus according to an embodiment disclosed herein includes a data obtaining unit configured to obtain degradation score data including a storage degradation score with respect to state of charge (SOC) and temperature of batteries of each of a plurality of vehicles and state data of the batteries and a controller configured to calculate, based on the state data, a first score related to a cycle degradation degree of a target battery that is a battery of a target vehicle among the plurality of vehicles in a discharging section of the target vehicle, calculate, based on state data of the target battery and the degradation score data, a second score related to a storage degradation degree of the target battery in the discharging section of the target vehicle, and manage a state of the target battery by calculating a stress score of the target battery based on the first score and the second score.
