The conducted electromagnetic interference of the wireless charging system with the bilateral LCC structure of electric vehicles is studied. According to the standard SAE J2954, a high-frequency circuit model of the conducted electromagnetic interference of the wireless charging system with a power of 3.7 kW is constructed. A method combining measurement and theoretical calculation is used to extract the high-frequency parasitic parameters of the coupling coil, cable and compensation circuit components. The modeling and simulation analysis of the conducted interference of the system are carried out by using the software ANSYS Maxwell and Simplorer. Simulation results show that the common mode interference is more significant than the differential mode interference in the frequency band of 150 kHz-30 MHz. The accuracy of the simulation model is verified by the conducted emission experiment of the wireless charging system.
