Characterisation of factors influencing the magnetic leakage field of a 7 kW wireless electric vehicle charging system

This paper presents a study of the influencing factors on magnetic leakage field of a 7 kW wireless electric vehicle charging (WEVC) system. The leakage field was measured in different test configurations and environments which afterwards were used to validate simulation models. The impact on magnetic leakage field distribution when varying the test environment and the test setup is presented in this paper. These results will be used to support discussion and recommendation in standards bodies related to the measurement of the magnetic leakage field of WEVC systems.
