This paper presents the development of fast charging infrastructure for Electric Vehicles (EVs) with the proportional increase in the number of EVs on highways. Development of charging infrastructure includes the installation of charging units in the urban or rural areas depending upon the need, forecast for the increased energy demand on power grid and consideration of capital invested on the system as a whole. Monte Carlo Simulations (MCS) have been performed to investigate the power demand, energy needed, utilization factor of each station and socket, and the Socket-to-EV ratio considering different waiting time scenarios. Socket-to-EV ratio varies with the limitation of waiting times offered to the EVs at charging stations. Socket-to-EV ratio is considered to be the parameter that tells the number of sockets needed to fulfill the charging need of EVs in a particular scenario. Utilization factor of charging sockets for different scenarios gives an estimate of power delivery hours of charging sockets to study the cost-and-benefit ratio of various cases.
