Plug-in module assembly for wireless electric charging

Abstract

A plug-in module for wireless charging a battery of an electronic device includes a chassis, a pad element connected to the chassis for the wireless transference of electromagnetic energy, and an electrical connector connected to the chassis opposite from the pad element. The pad element includes a wire coil of wire windings having an outer diameter and a non-zero inner diameter, an arrangement of ferrite bars including a plurality of individual ferrite bars positioned adjacent to the wire coil, and a metallic shielding frame that houses the wire coil and the arrangement of ferrite bars. The plug-in module may be incorporated into a wireless charging system for wireless transfer of electromagnetic energy for the charging of a battery of an electronic device, such as for example an electric vehicle. Circuitry of the system may include an AC/DC converter with integrated power factor correction, and a high frequency inverter for generating a kHz order electrical input to the wire coil.
