RES based EV battery charging system: A review.

Electric Vehicles (EV) are emerging due to ever increasing concerns on the energy issues and greenhouse gas effects. Also, due to the depletion of fossil fuels, electricity generated from Renewable Energy Sources (RES) like Photovoltaic (PV) arrays and Wind Turbine Generators (WTG) are used for charging the EV batteries which reduces the utility grid overload. A review on different power converter topologies which can be used in PV-EV and WTG-EV battery chargers are presented in this paper. Also, this paper reviews the various power converters which can be employed for interfacing RES-EV battery charger with the utility grid. This paper enlightens the researchers in the selection of appropriate power converters suitable for the stand-alone and grid-connected RES-EV battery charging systems. [ABSTRACT FROM AUTHOR]
