Aiming at the problems of weak coupling performance and poor misalignment-tolerant ability of the magnetic coupling structure of electric vehicle wireless charging system, this paper proposes a coil structure parameter design method. This paper analyzes the relationship between the system characteristics and the coupling coefficient of the wireless charging system based on the dual LCC resonant compensation network. Then, based on the analysis of the structure parameters of DD coils, a structure parameter design method to optimize coupling performance and misalignment-tolerant ability is proposed. Finally, the ANSYS MAXWELL 3-D finite element model of the DD magnetic coupling structure is built, and the validity and feasibility of the proposed design method are verified by simulation. Under the design method of coil structure parameter in this paper, the magnetic coupling structure can achieve excellent coupling performance and misalignment-tolerant ability.
