Universal base coil solution for interoperable system for stationary wireless EV charging

Abstract

This paper discusses requirements and potential solutions for interoperable wireless charging systems for electric and plugin hybrid vehicles. Such technology is known as resonant magnetic induction charging, also referred to as wireless electric vehicle charging (WEVC). Future requirements for a WEVC system are: low cost, small package, high power transfer and interoperability. This paper discusses interoperability requirements as a key factor for successful deployment of WEVC systems. One key aspect analyzed in this paper is primary and secondary coils requirements as they relate to interoperability. Theoretical and practical studies have been conducted and a suggested interoperable solution is presented.
