摘要
The power supply system includes a main power storage device (BA) and a plurality of sub power storage devices (BB1, BB2). The converter (12B) is sequentially connected to one of the sub power storage devices (BB1, BB2), and performs bidirectional voltage conversion between the selected sub power storage device and the power feed line (PL2). In a state in which there is no newly replaceable sub power storage device remaining after the connection switching process of the sub power storage device, a disconnection request for the sub power storage device is generated based on the SOC of the sub power storage device and the vehicle state. . However, when the condition regarding the temperature of at least one of the main power storage device and the plurality of sub power storage devices is satisfied, the generation of the disconnection request is prohibited to protect the main power storage device.
