  • Electric vehicles are in a way similar to internal combustion engine powered vehicles and have a finite range. The efficiency is thrice or five times when compared to internal combustion vehicles, lower maintenance cost, along with no air pollution are the advantages. In spite of these advantages, these vehicles have a very limited market outreach due to unavailability of charging stations outside urban areas. There are very few EV charge stations on the highway and freeway systems, and currently there is no network allowing EV drivers to travel coast to coast or even between states. On the other hand, petrol and CNG filling stations are now widely available specially the former at every nook and corner of the earth be it highways, state roads or local roads. However, for this EV technology to succeed, a large-scale charging network is vital. Further, conventional economics stifles the progress of such a network inception, and a new multi-facet solution is needed.
