ELECTRIC CAR WIRELESS CHARGING TRANSMISSION SYSTEM, AND TRANSMITTING COIL SWITCHING METHOD AND APPARATUS OF SAME

摘要

The invention relates to an electric car wireless charging transmission system, and a transmitting coil switching method and apparatus of same. The system comprises a plurality of wireless charging transmitting units successively arranged along a road, wherein adjacent wireless charging transmitting coils (L1, L2, L3) are arranged in an overlapping manner. The method comprises: switching the operating state of two adjacent wireless charging transmitting coils (L1, L2, L3) among the plurality of wireless charging transmitting coils (L1, L2, L3) successively arranged in the wireless charging transmitting units according to the resonant current of the wireless charging transmitting coils (L1, L2, L3), and switching the operating state of the wireless charging transmitting coils (L1, L2, L3) of two adjacent wireless charging transmitting units among the plurality of successively arranged wireless charging transmitting units according to the resonant current and the electromagnetic induction voltage of the wireless charging transmitting coils (L1, L2, L3). The electric car wireless charging transmission system, and the transmitting coil switching method and apparatus of same allow for automatic switching of the wireless charging transmitting coils (L1, L2, L3) and can realize charging of a moving electric car.
