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