Abstract
A power transmission control device included in a contactless power transmission system that transmits power by electromagnetically coupling a primary coil and a secondary coil from a power transmission device to a power receiving device so as to supply the power to a load of the power receiving device includes: a controller that controls the power transmission device. The controller includes: 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. In the device, normal power transmission from the power transmission device to the power receiving device is started after the setup process.
