The population of Electric Vehicle (EV) is tremendously increasing with the increase in fuel price and decrease in availability. As the number of EV increases, along with that the number of EV charging stations should also increase, which constitute a considerable charging impact on the grid from which the supply is taken. In this paper, in order to reduce this charging impact and its after effects, a topology for EV charging station is proposed which also promote the use of EVs. The proposed topology mainly consists of a charging station powered by the grid as well as the storage integrated solar PV system and a controller. The grid dependency of the charging station is reduced by using a renewable energy source (Solar PV) and for improving the system reliability a Battery Energy Storage System (BESS) is incorporated. The control technique helps to reduce the charging impact on the grid by controlling the charging current as per the system conditions. To make the EV Charging Station (EVCS) more customized, three different options (Quick, Green and Budget) for charging are given such that the customer is free to choose one among them according to his requirement. The cost of charging will vary according to the selected mode of charging. A smart Electric Vehicle charging station is designed and the charging current control in various grid conditions are tested and verified by u sing MATLAB Simulink model and the obtained results are included.
