The invention provides a wireless power transmission system and method as well as tracking-type transmitting coil devices. On the basis of the prior art in coil array wireless charging, the conventional fixed transmitting coil is designed to be a tracking-type transmitting coil, a plurality of sets of the tracking-type transmitting coil devices are arranged under the pavement along the road, and a vehicle positioning system is arranged; each set of the tracking-type transmitting coil device comprises the tracking-type transmitting coil, a guide rail, a pulley and a tracking device; the pavement direction of the guide rail is perpendicular to the advancing direction of an electric vehicle; each tracking-type transmitting coil is fixed on the corresponding pulley; a motor is mounted on each pulley; each tracking device acquires vehicle position information from a vehicle positioning system, sends a corresponding control signal to the corresponding motor of the pulley, and drives the pulley to move left and right on the corresponding guide rail, so that the corresponding tracking-type transmitting coil can achieve tracking of the electric vehicle. Through adoption of the wireless power transmission system and method as well as the tracking-type transmitting coil devices, the problem that a vehicle cannot drive on a high-charging-efficiency route and is low in charging efficiency is solved; the tracking-type transmitting coil devices can further be applied to other technical fields of wireless charging for charging efficiency improvement.
