In this article, a power transmission device including a communication part that performs communication with an external power transmission devices that transmits power, a transmission control part that controls the power transmission part to selectively transmit power based on a determination result from the determination part.Abstract:
There is provided a power transmission device including a communication part that performs communication with an external power transmission device that transmits power, a power transmission part that transmits power to a power receiving device that receives the transmitted power in a non-contact manner, a determination part that determines whether power can be transmitted, based on external power transmission information received by the communication part indicating a start of power transmission by the external power transmission device, and a power transmission control part that controls the power transmission part to selectively transmit power based on a determination result from the determination part.read more
