N2 - In-motion wireless power transfer (WPT) system is expected to achieve unlimited driving range of electric vehicles (EV s) independent of their battery capacity. Previous research has developed an in-motion WPT system with individual vehicle detection units for power transmission control. However, in this paper, a charging infrastructure of in-motion WPT is designed and implemented based on a sensorless vehicle detection system only using power converters and power transmitting coils. In addition, this paper presents a resonant capacitor integrated road coil considering construction complexity and safety issues due to resonant high voltage. Furthermore, influences of road structural materials are investigated to adopt a cheap and compatible structure. The feasibility of the constructed in-motion WPT system is demonstrated by a driving test.
