Abstract:
Recent years have witnessed the booming development of electric vehicles (EVs). Wireless charging for EVs has been extensively studied due to its advantages of automation, safety, and convenience. One of the main obstacles facing EV wireless charging is misalignment tolerance. This paper proposed a novel misalignment tolerant compact EV wireless charging system based on the hybrid compensation topology, which was a series connection of the LCC-S and the S-S topologies. A set of unipolar coils and a set of quadrupole coils were employed as the power transmission coils of both topologies in the EV wireless charging system to improve misalignment tolerance on both the moving direction and the door-to-door direction. The primary quadrupole coil was utilized both as the transmitting coil and as the compensating inductor of the LCC-S topology, realizing a compact and low-cost structure. The proposed system achieved good misalignment tolerance on both directions. Experimental results validate the proposed wireless charging system. © 2022 Chin. Soc. for Elec. Eng.
