HYBRID VEHICLE TECHNOLOGY
 
ABSTRACT

          In the 21st century, better fuel economy and achieving tighter emission norms are bound to be the main areas of growth in Automotive Technology. Hybrid vehicle strikes the perfect balance between these objectives. The heat engine-electric hybrid vehicle, first conceived as long ago as 1900, is intended to overcome the limited range and long recharge time of pure electric vehicle that relies for its energy source only on its battery. It usually achieves this desirable objective by combining electric drive with a conventional heat engine using fossil fuel energy source. 

         The International Electrotechnical Commission defines a hybrid vehicle as one in which propulsion energy, during specified operational missions, is available from two or more kinds or types of energy stores, sources, or converters. At least one store or converter must be on-board. A hybrid electric vehicle (HEV) is a hybrid vehicle in which at least one of the energy stores, sources, or converters can deliver electric energy.
