Driving Range Extension of EV With On-Road Contactless Power Transfer—A Case Study

As future electric vehicles (EVs) emerge, achievable driving range by these vehicles remains a major bottleneck. A battery EV has a fairly limited driving range per charging and takes a long time to charge. Moreover, the existing technology only enables stationary charging, which means that an EV has to be parked during the duration of its charge replenishment. Contactless power transfer (CPT) system presents the opportunity of on-road charge replenishment of EVs. This paper presents case studies which illustrate the effect of on-road charge replenishment on driving range of an EV for varying levels of power transfer by the CPT system in urban and highway driving scenarios.
