Power transmission device, power transmission method, program, power receiving device and power transfer system
First Claim
1. A power transmission device comprising:
- 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.

11. A power receiving device comprising:
-
a receiving-side communication part that communicates with one or more power transmission devices that transmit power; a power receiving part that receives power transmitted from the power transmission device in a non-contact manner; a received power level detection part that outputs a detection result in accordance with a received power level, based on first transmission power transmitted from the power transmission device, the first transmission power increasing discretely; a received power information derivation part that derives information of power reception specifying a status relating to transmission power to the power receiving device, based on a detection result from the received power level detection part, for each of the power transmission devices; and a power transmission device selection part that selects the power transmission device based on the derived information of power reception and causes the receiving-side communication part to transmit a power transmission request for requesting the selected power transmission device to transmit power. - View Dependent Claims (12)

13. A power transfer system comprising:
-
a plurality of power transmission devices that transmit power; and a power receiving device that receives power transmitted from the power transmission devices, wherein each of the power transmission devices, includes a communication part that communicates with other power transmission device, a power transmission part that transmits power to the power receiving device 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.
