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. In response to decrease in SOC of the selected sub power storage device being used, a request to switch the sub power storage device is generated and accordingly a switching process for a relay is performed. Here, while a process for starting or stopping an engine is being performed, the request to switch will not be generated even when decrease in SOC is detected. Likewise, while a process for switching the sub power storage device is being performed, the process for starting or stopping the engine will not be started even when a request to start or stop the engine is generated.
