When the temperature of a battery is high, the output power of the battery is limited to suppress the temperature rise. Upon fulfillment of three conditions of (i) the ambient temperature is equal to or higher than a predetermined temperature, (ii) the vehicle traveling load is equal to or greater than a predetermined traveling load, and (iii) the operating load of a battery cooling device is equal to or greater than a predetermined operating load, the output power of the battery is limited using a high-load output limiting value less than an output limiting value for the normal condition in a temperature range equal to or higher than a second power restrictive lower limit temperature that is equal to or lower than a first power restrictive lower limit temperature for the normal condition.
