A study of designing a universal inductive charger for Electric Vehicles

Inductive charging for Electric Vehicles (EVs) applies high frequency alternating currents in the transmitter pad or coil to inductively transfer power through loosely coupled induction to the receiving coil in EVs. The emerging of multiple EVs calls for a universal charging system that can charge most EVs efficiently and safely in variable external environments. This paper presents a comprehensive summary of considerations for designing a universal inductive charger, including that in hardware design such as topology, charging pads and batteries, and transient information such as voltage/current, status, weather, faults. Different options are provided and compared, and the suggested solution is reached after the analysis.
