N2 - This paper focuses on the design of the magnetic coupler in the wireless charging system for electric vehicles. A solenoid type magnetic coupler is used for the better ability of magnetic coupling than the plate type magnetic coupler under the condition of mid-range wireless power transfer. The factors of coupling coefficient are analyzed in two kinds of ways, magnetic circuit theory and mutual inductance theory. A solenoid type magnetic coupler with new core structure design and new winding design is proposed in consideration of coupling coefficient, utilization factor of core, winding distribution, horizontal position misalignment and horizontal angle misalignment. The whole design meets the requirements of 3.3 kW wireless charging system and is simulated by 3D finite element analysis software.
