Interoperability Testing Coil for EV Wireless Power Transfer System

Abstract

Based on the interoperability requirements for wireless power transfer system for electric vehicles, this paper discusses the interoperability requirements for coils, which regard to several parameters, including transferred power, magnetic efficiency, current and voltage limitations, and electric and magnetic field exposure. A group of DD coils for WPT2/Z2 are designed as testing coils, which can test the interoperability of different types of coils. Finally, experiments have been conducted and show that the proposed testing coils are feasible.
