Emerging energy sources for electric vehicle charging station

The fossil fuels which are the source of energy for the traditional vehicles have their reserves on the verge of extension. Also, exhaust gases from these vehicles are degrading the environment by increasing the content of greenhouse gases. To combat these issues, the electric vehicles (EVs) are emerging as a new mode of transportation. In recent research articles, the EV charging stations (EVCSs) are consuming power from either the grid or a solar grid system. If the EV is charged from grid, then it should not be considered environment-friendly as grid power is mostly generated by burning coal. In the long run, if EVs come in bulk grids, they would get overloaded, thus affecting the power quality. The efficient energy management of sources available for charging is mandatory for the persistence of these vehicles. The paper aims to rectify energy crisis by suggesting alternative sources for energising the EVCS. A new hybrid system consisting of PV, WTG and fuel cells is proposed. This system is independent of the grid supply. Hence, even with increasing inrush of EVs, the power quality of grid will not suffer. In this paper, an exhaustive review of different topologies of power converters for EVCS and their comparison are carried out. Furthermore, envisaging the future of RES for the charging station to ensure sustainable development.
