Patent ID: 8274254

Claim:
A power transmission control device included in a contactless power transmission system that transmits power by electromagnetically coupling a primary coil from a power transmission device to a secondary coil from a power receiving device to supply the power to a load of the power receiving device, the power transmission control device comprising: a controller that controls the power transmission device, the controller including: a negotiation processing section that performs a negotiation process of contactless power transmission; and a setup processing section that performs a setup process of the contactless power transmission based on a result of the negotiation process, the controller exchanging information between the power transmission device and the power receiving device during the negotiation process and the setup process, the controller confirming whether or not the information exchanged between the power transmission device and the power receiving device matches with each other, the information including at least one of standard information and coil information, and the controller executing a normal power transmission from the power transmission device to the power receiving device.
