Abstract:
1. A power transmission control device included in a contactless power transmission system in which power is transmitted from a power transmission device to a power receiving device by electromagnetically coupling a primary coil and a secondary coil and the power is supplied to a load of the power receiving device, the power transmission control device comprising: a controller that controls the power transmission control device; a load condition detection circuit that detects a load condition on a power receiving side; and a storing section storing power transmission side system information that shows a load condition detection method with which the power transmission device is able to cope with the controller collating the power transmission side system information stored in the storing section and power receiving side system information that is received from the power receiving device and shows a load condition detection method that the power receiving device is able to cope, and determining whether or not the power transmission side system information and the power receiving side system information are compatible, the controller determining the load condition on the power receiving side based on threshold information received from the power receiving device and load condition detection information from the load condition detection circuit.
