Research on Improving the Interoperability of Electric Vehicle Wireless Power Transfer

Current electric vehicles have problems such as low charging efficiency, low output power, and poor interoperability during the wireless charging process. This is due to differences in the design parameters of different manufacturers or the offset of the coil. This article uses parameters closely related to the nature of the system: normalized angular frequency A, quality factor Q, Qf to simplify the analysis of the LCC-LCC electric vehicle wireless power transfer system, and obtain a simplified mathematical model. Then use the above model to analyze the nature of the system. A method is proposed to improve the interoperability of the system by adjusting the frequency. Finally, the feasibility of the above theory is verified by simulation and experiment. Provide a reference for the research on the interoperability of electric vehicle wireless power transfer.
