SummaryThis paper presents a study of the magnetic leakage field of a 7 kW wireless electric vehicle charging (WEVC) system. The leakage field was measured in different test configurations and environments. Typical system parameters, such as coil offset and air gap were evaluated in order to determine their influence on the leakage field distribution. All measured results were then validated by magnetic field simulations. Based on the results of this study, a magnetic leakage field assessment method based on simulation is proposed.
