Abstract: The present disclosure relates to charging a battery included in a robot. Standard deterioration cost information may be determined and stored based on an ambient temperature, a current rate, and a depth of discharge. This may include determining one standard deterioration cost information from among the stored standard deterioration cost information based on an ambient temperature of the robot and a current rate during an operation of the robot, and determining at least one depth of discharge at which the standard deterioration cost is equal to or less than a predetermined threshold based on the determined one standard deterioration cost information. The operation may be performed by repeating a process of charging and discharging the battery by a charge and discharge method based on the at least one depth of discharge.
