Abstract

The study evaluates the grid-side implications of on-route, opportunistic wireless charging for electric vehicles (EV), where EVs are charged during routine traffic dwell, relative to a conventional depot plug-in regime that concentrates charging after service. Using a city scale microscopic traffic–power simulation over a six-hour period with a mixed EV fleet, study analysis integrates vehicle activity, station utilization, and feeder-level indicators. The findings show that the distribution of uniform energy across operating hours leads to a significant reduction in instantaneous loading, increases the utilization of available distribution capacity and reduces load peaks. Conversely, compressing charging into a terminal window alone results in the generation of a high magnitude wave. The key findings illustrate that temporal regulation of charging is a important factor in achieving grid compatibility, and opportunistic wireless top-ups represent a viable mechanism for aligning urban EV charging with distribution grid operating envelopes. It further motivates field trials coupling control policies with observed traffic and feeder limits.
