Abstract
Electric vehicles with wireless charging use mutual induction to transfer electrical energy to the battery bank, eliminating the need for wires and physical connection. Wireless power pads and the distance between primary and secondary coils are the critical challenges in electric vehicle (EV) wireless charging. The chapter analyzes an existing DD coil shape with the addition of a ferrite core across the coil to create a highly efficient power pad for EV wireless charging. Due to the unusual flow distribution of flux, a 3D FEA method is being employed for the study. A simulation setup with different misalignment is developed in the Ansys Maxwell® 2015 to validate the efficacy of the model. A graphical representation of both coupling coefficient and mutual inductance with different misalignment is proposed.
