Abstract Scope |
Advancing dynamic wireless charging systems (WCS) is motivated by the increased interest in optimizing electric vehicle (EV) range and performance. Ferrite material systems are used in dynamic charging devices typically as magnetic couplers that enhances power transfer with low levels of power loss but are currently limited by their weight and size. This work examined various spinel ferrite compositions (e.g., Ni1-xZnxFe2O4) and processing approaches to produce candidate materials for lighter-weight alternative devices for WCS. An overview of the impact of intrinsic, extrinsic, and external properties (e.g., chemistry, microstructure, external magnetic field) on the tailorability of the magnetic performance will be presented.
