A wireless charging system for electric vehicles is characterized by comprising a vehicle-mounted portion and a charging pile portion; the charging pile portion comprises a control system, a track fixed to a parking space, a position detector mounted on the track, a base mounted on the track, a manipulator mounted on the base, and a wireless charging panel mounted at the top of the manipulator; the vehicle-mounted portion comprises a wireless charger and a position feedback device, the wireless charger is fixed to a chassis of an electric vehicle, and the position feedback device is fixed to the wireless charger. The wireless charging system has the advantages that through active judgment on the position of a wireless charging receiving terminal, the manipulator moves the wireless chargingpanel to a position nearest to the wireless charger by movement on the track and its degree of freedom, so that requirements on the parking position accuracy of the electric vehicle can be reduced, energy loss can be also decreased, energy transmission efficiency can be improved, charging speed can be increased, large-area wireless chargers do not need to be added to the bottom of the electric vehicle, and the integrity of the bottom structure of the electric vehicle is not damaged.
