Research on Interoperability of Pickup Terminals in Dynamic Wireless Charging of Electric Vehicles

Due to the diversity of the compensation circuit topology of the DWPT system, when the transmitter and the pickup end adopt different matching schemes for power transmission, the operating characteristics are quite different. In order to solve this interoperability problem, this paper assumes that the primary side adopts the LCC topology, analyzed the output power, efficiency and other parameters of the three matching schemes of LCC-S, LCC-P and LCC-LCC, and proposed a pick-up terminal topology identification method based on the dynamic detection of the primary DC side current. To improve the working condition of the system, the original topology is switched to the obtained topology, and finally the simulation model of the system is established to verify the effectiveness of the proposed method.
