Summary of EMC Test Standards for Wireless Power Transfer Systems of Electric Vehicles

As an important part of the new automobile four modernizations, wireless power transfer (WPT) system solves a series of problems of the conductive charging way, and its application is better for the accelerating development of electric vehicles (EVs). At the same time, the electromagnetic safety problem of WPT system also gradually becomes one of the focus of public attention. However, due to the imperfection of relevant standards and regulations, the wireless charging system of electric vehicles is currently in the state of prototype and demonstration operation. The standardized wireless charging system will play a positive role in promoting the large-scale electrification of the wireless charging system of electric vehicles. This paper focuses on the research of EMC of the wireless charging system of electric vehicles. Firstly, based on the structure of the wireless charging system, the possible EMC problems are introduced. Furthermore, the existing EMC standards of wireless charging at home and abroad are compared and analyzed, and the test layout is introduced. Relevant content will provide guidance for enterprises in the development and testing of wireless charging systems.
