Abstract

In order to solve the problems of weak battery life and few charging places of electric vehicles, dynamic wireless charging system (DWCS) came into being. In this paper, the significant mutual inductance fluctuation and the internal coupling of the traditional DD coil in the process of dynamic charging are deeply studied. The size and parameters of the coil are optimized by theoretical design, and a large number of software simulation experiments and experimental verification are carried out on the design scheme. Firstly, the size of transmitting coil is optimized to solve the problem of high mutual inductance fluctuation in dynamic charging process. On this basis, the magnetic field distribution of DD coil was analyzed, the influence of magnetic coupling structure change on coil parameters was compared, the optimization direction of coil was established, a new DD coil was designed, and the mutual inductance function of new DD coil was deduced. Then the electromagnetic simulation software is used to simulate and the experimental platform is built to verify the rationality and feasibility of the design.
