摘要： This control device for an electric vehicle is provided with: a discharge control unit which, when the electric vehicle has been turned off, if the SOC of the battery is within a prescribed range in which the battery is prone to deteriorate, performs control for discharging the battery until the SOC has left the prescribed range; a travelable distance calculation unit which calculates the travelable distance of the electric vehicle using the SOC and a travel coefficient; and a travel coefficient correction unit which, before and after performing control for discharging the battery is performed by the discharge control unit, corrects the travel coefficient such that the travelable distance calculated by the travelable distance calculation unit is reduced.

摘要： This electric vehicle control device is provided with: an efficiency control unit which, during travel of the electric vehicle, in a state in which the battery is prone to deteriorate, increases the rate of consumption of the power charged in the battery by performing control for reducing the efficiency of the motor; a travelable distance calculation unit which calculates the travelable distance of the electric vehicle using the SOC of the battery and a travel coefficient; and a travel coefficient correction unit which, before and after the efficiency control unit performs control for reducing the efficiency of the motor, corrects the travel coefficient such that change in the travelable distance calculated by the travelable distance calculation unit is reduced.
