19. A method performed by a non-contact power transmission apparatus, the method comprising:
-
generating, by a power supply circuit, electrical power to be provided to one of a first power transmission antenna and a second power transmission antenna, which are each connected to an output of the power supply circuit via a switch; communicating, via a communication interface, with a device; and controlling, by a control unit, the switch based on a state of the device obtained from the device via the communicating.
