FIELD: electrical engineering.
SUBSTANCE: wireless power supply system of the invention performs a wireless power supply between the electric power transmitting coil installed in the parking space, and receiving an electric power coil mounted on the vehicle, transmits the estimated power for estimating the parking position from the transmitting electric power of the coil to the receiving coil in the parking operation of the vehicle in the parking lot and sets the excitation frequency for the estimated power equal to the frequency below the common-mode resonance point or above the antiphase resonance point.
EFFECT: increased accuracy of assessing the position of the vehicle when charging.
