Abstract—Plug-in charging has served the electric vehicle industry adequately for a decade, but it is becoming an increasingly visible friction point as EV adoption accelerates. Cables wear out, connectors corrode, and the simple act of remembering to plug in is, according to a surprising number of EV owners, the most annoying part of owning the car. Wireless power transfer (WPT) via magnetic resonance coupling offers a cable-free alternative, but achieving the combination of high efficiency, reasonable tolerance to coil misalignment, and electromagnetic compliance that a real parking environment demands has proved harder than early demonstrations suggested. This paper presents a 11.2 kW WPT system built around an LCC-S compensation topology, silicon carbide (SiC) MOSFET switching at 85 kHz, and a DDQ receiver coil that is specifically shaped to maintain coupling as the vehicle parks over the ground pad. Operating across an air gap of 100–200 mm with lateral misalignment up to 100 mm, the system achieves an end-to-end efficiency of 93.4 % and charges a 40 kWh battery from 10 % to 80 % state-of-charge in approximately 2.8 hours. Electromagnetic field (EMF) levels at 20 cm from the pad edge remain below the 6.25 µT ICNIRP reference level throughout operation. The results position the proposed design as a credible candidate for Level 2 home and public WPT charging infrastructure.
