Abstract
Due to the inherent misalignment variations in wireless electric vehicle (EV) charging systems, particularly in dynamic charging modes, it is essential to acknowledge the misalignment performance in the design and optimization of the coupling coils and the shielding layers. In this work, a heuristic inductive link design approach is presented, in which the coupling performance of rectangular RIPT coils is evaluated over a range of lateral misalignments for different coil parameters and shielding layer thickness. Accordingly, recommendations are made on the inductive link design that provides good coupling behavior, sufficiently high power transfer efficiency and effective shielding performance over a wide range of lateral misalignments.
