Wireless charging is a popular upcoming technology with uses ranging from mobile phone charging through to electric vehicle (EV) charging. Large air gaps found in current EV wireless charging systems (WCS) pose a hurdle of its success. Air gaps in WCS cause issues in regards to efficiency, power transfer and electromagnetic compatibility (EMC) leakage issues. A static In-Wheel WCS (IW-WCS) is presented which significantly reduces the issues associated with large air gaps. A small scale laboratory prototype; utilizing a standard 10mm steel reinforced tyre, has been created and compared to a typical 30mm air gap. The IW-WCS has been investigated by experimental and finite element method (FEM) based electro-magnetic field simulation methods to validate performance.
