Claim:
1. A power supply device, comprising: a connecting unit that transmits electric power to an external power recipient device via a power line; a connection state determiner that determines that the external power recipient device is physically connected to the connecting unit via the power line; a wireless communication unit including a communication antenna and a communication processor that wirelessly communicates with the external power recipient device, wherein the communication processor transmits a carrier wave according to a high-frequency signal via the communication antenna, and wherein the high-frequency signal has a higher frequency than a frequency of the electric power; a communication control unit that, in a case where the connection state determiner determines that the external power recipient device is physically connected to the connecting unit via the power line, is configured to initiate control of the wireless communication unit to transmit the carrier wave to acquire from the external power recipient device information related to power receiving capability corresponding to the external power recipient device via the communication antenna of the wireless communication unit, and in a case where the connection state determiner determines that the external power recipient device is not physically connected to the connecting unit via the power line, the communication control unit is configured to initiate control of the wireless communication unit to stop transmission of the carrier wave; a power receiving capability specifier that specifies the power receiving capability of the external power recipient device on the basis of the acquired information related to the power receiving capability; and a power control unit that is configured to transmit electric power compatible with the external power recipient device on the basis of the specified power receiving capability.
