Abstract: When a vehicle approaches a parking space, a ground controller excites a power transmission coil using an excitation pattern signal containing identification data, and a vehicle controller acquires the identification data from the excitation pattern signal received by at least one of subcoils. Then, a communication unit transmits the acquired identification data to the ground unit. The ground controller pairs the power transmission coil and the power reception coil with each other when the identification data contained in the excitation pattern signal and the identification data transmitted from the vehicle controller match each other. Also, the pairing is canceled if the identification data received by the subcoil provided on the front side and the identification data received by the subcoil provided on the rear side are different from each other.

Abstract: 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.

Abstract: A power supply device supplies power from a power transmission coil to a power reception coil of a vehicle in a non-contact manner. The power supply device has a communication unit that receives a startup signal for activating the power supply device. A notification unit notifies a state of the power supply device.
