description This paper proposes a novel coupling structure wireless power transfer (WPT) technology for improving the charging and recharging efficiency between electric vehicles (EVs) in the case that the transmitting and receiving coils are not exactly aligned. During the process of wireless power transmission, if the relative position of the coils located on each objective is randomly changed, a change in the mutual inductance occurs, which critically leads to fluctuation in the WPT system output. In order to improve the tolerance of the EV WPT system, considering coupling structure misalignment and the deflection caused by relative location changes, a double-layer coupling structure with solenoid pads and double-D pads (SP-DDP coupling structure) is designed for deployment on the side of EVs. Then, the coupling structure is developed through parametrized optimization. Finally, the established coupling structure is evaluated through simulations and an experiment using a prototype, the results of which demonstrate that the proposed coupling structure can achieve good anti-misalignment and anti-deflection performance, realizing a system efficiency of 92.65% and an output power of 192.02 W for the designed EV WPT system.
