Abstract
An electric vehicle includes: a vehicle drive apparatus configured to receive electricity to generate vehicle drive power and to generate electricity; a secondary battery that selectively receives and outputs electricity from/to the vehicle drive apparatus; a current sensor that selectively detects (a) an electric current to be input into the secondary battery and (b) an electric current output from the secondary battery; and an electronic control unit configured to control charging and discharging of the secondary battery, and configured to calculate, using a detected value from the current sensor, an evaluation value indicating a degree of deterioration of the secondary battery due to non-uniformity in salt concentration in the secondary battery caused by charging and discharging of the secondary battery. The electronic control unit is configured to execute a capacity-raising control in which a remaining capacity of the secondary battery is raised when the evaluation value reaches a prescribed threshold.
