Abstract
A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to a selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. Connection of the sub power storage device is switched and, when the last sub power storage is used, a request to disconnect the sub power storage device is generated based on the SOC of the sub power storage device and the vehicle state. Specifically, where the SOC is included in a disconnection forced region in which the SOC is smaller than a reference lower limit, the sub power storage device is forced to be disconnected regardless of the vehicle state. Where the SOC is included in a disconnection permitted region in which the SOC is higher than that in the disconnection forced region, the disconnection request is generated on condition that the vehicle is in such a state that will not affect vehicle's drivability.
