Hybrid Electro Vehicle

Abstract

Now-a-days, the environmental impact of automobiles is increasingly becoming one of the most important social issues. Major environmental impact is smog producing gases [2]. These gases emitted from the vehicles may pollute the air, water, soil and it results in acid rain, global warming, nausea and also leads to death. To meet current and future regulations with less emission of gases, alternative technologies like Hybrid Electric Vehicle (HEV) is being developed. A HEV is a type of hybrid vehicle that combines a conventional Internal Combustion Engine (ICE) system with an electric propulsion system. These hybrid vehicles reduce the discharge of pollutants from the vehicles powered by fossil fuel. These vehicles are propelled by electric motors which is powered by the energy stored in the batteries [5]. The battery charges when the vehicle is in running condition. HEVs are fuel efficient and is good to the environment. It produces twice as many miles per gallon. The presence of this method is intended to achieve either better fuel economy than a conventional vehicle.
