Abstract
A battery management device to be mounted on an electric vehicle including a driving wheel, a traveling motor configured to generate a driving force for the driving wheel, and a battery configured to store electric power to be consumed by the traveling motor. The battery management device includes a detector configured to detect a state of the battery, and a controller configured to calculate a characteristic value indicating performance of the battery based on an output of the detector, and manage charging and discharging of the battery based on the characteristic value. The controller is configured to, when the characteristic value has deterioration, determine whether the deterioration of the characteristic value is reversible deterioration based on the output of the detector. The controller is configured to, upon determining that the deterioration of the characteristic value is the reversible deterioration, return the characteristic value to a value before the deterioration.
