As future Electric Vehicles (EVs) emerge, achievable driving range by these vehicles remains a major bottleneck. A Battery Electric Vehicle (BEV) 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 CPT system in urban and highway driving scenarios.@en

The use of contactless power transfer systems 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 the driving range of an EV for varying levels of power transfer by CPT system. On-road charge replenishment of idle EV at traffic signal is considered for urban driving scenario whereas on-road charge replenishment of an EV in motion is considered for highway driving scenario.@en

Contactless power transfer (CPT) is a safe, convenient and reliable way of transferring power in many applications where there exists no physical contact between the source and the load. In this paper, general design criteria are described for efficient power transfer in a CPT system. The need for compensation has been discussed and general conditions for achieving bifurcation-free operation for each compensation topologies have been derived. Advantages of using Series-Series compensated topology over other topologies are discussed. Constant current and constant voltage modes of operation of Series-Series topology and conditions for these modes of operation are presented. An experimental CPT setup is built to validate the theory developed.@en
