Research on Electromagnetic Compatibility for Wireless Charging System of Electric Vehicles

Currently, there are no specific standards on electromagnetic compatibility (EMC) test for wireless charging system of electric vehicles (EVs). However, the EMC test items have been summarized in some international standards. And the national standard is under developing. In order to support the formulation of corresponding national standards and regulations, promote the rapid development of EVs industry and support the implementation of the national strategy of new energy vehicles (NEVs) and intelligent network vehicle, we carry out the EMC test for wireless charging systems. In this paper, the wireless charging system of EVs is taken as the research object, which can also been called equipment under test (EUT). Firstly, an introduction of the research status was summarized. And then, the influence parameters such as output power and offset are analyzed. Based on the analysis, the EMC test was implemented to evaluate the EMC performance of EUT. Finally, the relevant research results will provide support for the formulation of national standard.
