CONTACTLESS POWER TRANSMISSION SYSTEM AND POWER-RECEIVING DEVICE

This contactless power transmission system is equipped with a plurality of power-transmitting devices and a power-receiving device. The plurality of power-transmitting devices each have a primary-side coil into which AC power is inputted. The power-receiving device has a secondary-side coil capable of receiving AC power in a contactless manner from one of the primary-side coils of the plurality of power-transmitting devices. The power-receiving device is provided with a holding unit for holding the primary-side coils, and an identification unit. The identification unit identifies the target coil among the plurality of primary-side coils held by the holding unit.
