Summary: | The invention provides a battery management device for an electric vehicle, which can fully exert the capability of a battery. This electric vehicle is provided with: drive wheels; a travel motor that generates power for the drive wheels; and a battery for storing power consumed by the travel motor. The battery management device mounted on the electric vehicle is provided with: a detection unit that detects the state of the battery; and a controller that calculates a characteristic value indicating the capacity of the battery on the basis of the output of the detection unit, and manages charging and discharging of the battery on the basis of the characteristic value. Furthermore, when there is deterioration in the characteristic value, the controller determines whether or not the deterioration in the characteristic value is reversible deterioration on the basis of the output of the detection unit, and when it is determined that the deterioration is reversible deterioration, the controller returns the characte |
