When a vehicle (20) approaches a parking space (32), a ground controller (13) sets a power transmission coil (11) to first excitation in which the power transmission coil (11) is excited in an excitation pattern containing identification data. A vehicle controller (24) pre-charges a capacitor (C3) connected to a power reception coil (21) after the vehicle (20) approaches the parking space (32). Further, the vehicle controller (24) acquires the identification data when the power transmission coil (11) is in the first excitation, and transmits the acquired identification data to the ground unit (51). The ground controller (13) pairs a power transmission device (101) and a power reception device (102) with each other if the identification data contained in the excitation pattern and the identification data acquired by the vehicle controller (24) match each other.
