BATTERY MANAGEMENT METHOD, BATTERY DEVICE, AND VEHICLE COMPRISING BATTERY DEVICE

A battery device receives a state of charge (SOC) a SOC setting range, charge at least one battery pack, estimates a SOC based on state information of the at least one battery pack, monitors whether the estimated SOC reaches a charging reference value corresponding to an upper limit of the SOC setting range, and stops charging when it is confirmed through a result of the monitoring that the estimated SOC reaches the charging reference value. The SOC setting range may be determined based on driving information of a vehicle, and may be within a SOC limiting range in which degradation of battery cells included in the at least one battery pack is the lowest.
