An electric vehicle includes a secondary battery which performs charge from an external power source and travels by using power of the secondary battery. The electric vehicle further includes: a charging unit which charges the secondary battery with power supplied by connecting a charge plug to the external power source; and a control unit which performs information acquisition or control for respective constituent elements. The control unit acquires a remaining capacity value from the secondary battery upon charge. When the control unit judges that a high charge capacity state continues a predetermined number of times, the control unit performs charge up to a charge capacity lower than a full electric capacity amount. This can suppress degradation of the secondary battery by charge.
