Abstract

Misalignment during wireless charging of EVs can lead to low efficiencies (<85%) of power transfer which can lead to thermal issues and high leakage fields. This paper explores the most optimal solution towards a misalignment tolerant system. To that end, a DD-DDQ coil system with series-series compensation combined with an impedance matching control algorithm is explored. A multi-objective optimization approach is presented to visualize the trade-off between the design aspects which result in high misalignment tolerance. Finally, the results are compared with DD-DD coil designs to quantify the advantage of the proposed system.
