DEVELOPMENT OF AN INTEGRATED POWER CONVERTER FOR FAST CHARGING AND EFFICIENCY ENHANCEMENT IN ELECTRIC VEHICLES

Electric Vehicle (EV) industry is booming from the last two decades due to the foreseen reduction in fossil fuels. The main hindrance confronted by the EVs is the low reliable storage capacity and reduced conversion efficiencies. Major studies are going on in the field of power density improvement in power electronics used in electric vehicles leading to the development of highly efficient EVs. Reduced size of the converters, storage system, response of tight speed controllers are the major challenges in Electric vehicle designing segment. The charging solutions for different segments of Electric vehicles are the other areas posing challenges. In this paper a new method of charging technique is proposed for Low, Medium and High power Electric vehicles. The charging topology increases the efficiency of the EVs by harvesting the energy dissipated during the braking period and further utilising it for the propulsion with the aid of high efficient light weight storage devices like Ultra capacitors. By this system the size of batteries and charging time can be drastically reduced.
