Abstract:
An electrically-driven vehicle 10 comprises a chargeable and dischargeable battery 20, a charger 16 that charges the battery 20 using a supply of electric power from an external power supply 100, an accessory unit 19 that is driven by a supply of electric power from at least one of the battery 20 and the charger 16; and a PM-ECU 18 that controls drive of the charger 16 so that the charged amount of the battery does not exceed a predetermined charging upper limit. The PM-ECU 18 sets the charging upper limit used when the accessory unit 19 is being driven, lower than the charging upper limit used when the accessory unit 19 is not being driven in order to avoid overcharging when excessive electric power is supplied from the accessory unit 19 to the battery 20.
