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. When the power transmission coil is set to the first excitation, a vehicle controller acquires the identification data from the excitation pattern received by a power reception coil, and transmits the identification data to a power transmission device. Then, the ground controller determines whether or not the identification data contained in the excitation pattern when setting the power transmission coil to the first excitation and the identification data acquired from the excitation pattern received by the power reception coil match each other. If both pieces of identification data match each other, the ground controller sets the power transmission coil to second excitation.
