1. A power transmission control device provided in a power transmission device of a non-contact power transmission system, the non-contact power transmission system transmitting power from the power transmission device to a power reception device by electromagnetically coupling a primary coil and a secondary coil to transmit the power to a load of the power reception device, the power transmission control device comprising:

  • a power-transmission-side control circuit that controls the power transmission device,the power-transmission-side control circuit performing an authentication process based on authentication information that is transmitted from the power reception device to determine whether or not power transmission can be performed before normal power transmission is started, the power-transmission-side control circuit performing control of the normal power transmission when the power-transmission-side control circuit has determined that power transmission can be performed, and controlling maximum transmission power during the normal power transmission to conform to a rated power of power-reception-device-side based on at least part of the authentication information.
