摘要

A power transmission control device (20) comprised in a contactless power transmission system for transmitting power by electromagnetically coupling a primary coil (L1) and a secondary coil (L2) from a power transmission device (10) to a power receiving device (40) so as to supply the power to a load (90) of the power receiving device (40) comprising: a controller (22) for controlling the power transmission device (10). The controller (22) comprises: a negotiation processing section (37) for performing a negotiation process of contactless power transmission; and a setup processing section (38) for performing 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 (10) to the power receiving device (40) is started after the setup process.
