Abstract

The invention discloses a long-distance WPT system multi-relay coil coupling structure optimization method and device, and the method comprises the steps: determining all permutation and combination models according to different coil size types, building a WPT system efficiency model under different permutation and combination models, and, according to the WPT efficiency model, analyzing factors influencing WPT system efficiency improvement under coils of different sizes and optimization design under different permutation and combination models; and optimizing the distance between adjacent coils in combination with various factors, and determining the permutation and combination with the optimal efficiency of the WPT system under the coils of different sizes by comparing and analyzing the efficiency of different permutation and combination models after optimization. According to the method, the permutation and combination with the optimal efficiency are determined by optimizing the distance between the adjacent coils, so that the system always works in an efficient state in the energy transmission process, and the problem that the efficiency is low in the middle and long distance wireless power transmission process is effectively solved.
