Abstract

Devices and methods for supply or receiving electric power. A power supply method may include specifying a type of a power source, specifying a power receiving capability of a power receiving device, performing collation of the specified type of the power source with the specified power receiving capability, and controlling transmission of electric power from the power source of the specified type to the power receiving device based on the collation. A power receiving method may include specifying a type of a power source, specifying a power receiving capability of a power receiving device, performing collation of the specified type of the power source with the specified power receiving capability, and controlling, based on the collation, selective conversion of electric power transmitted from the power source of the specified type to the power receiving device.
