HYBRID ELECTRIC VEHICLES: A GENERAL OVERVIEW

Transportation including cars, buses, aircrafts etc. is significant for whole realm because it offers mobility. A surplus of energy intake and discharge of pollutants is stimulated by transportation. These Environmental factors and decreasing fuel reservoirs have changed the concept of combustion engines based vehicles. This paper provides a general overview of the Hybrid Electric Vehicles and benefits of using the HEVs over the normal vehicles. Hybrid electric vehicles can offer a way out to the hazards exposed to the globe and have the capability to perform relative to that of a typical vehicle with evident progress in fuel efficiency, energy conservation and tailpipe emissions. The performance of HEVs is significantly determined by its construction and modules. The core modules include internal combustion engine (ICE), single or multiple energy storage system (ESS), electric motor, bidirectional converters and control unit. Each unit along with gains and downsides of HEV is discussed in this paper. Keywords— internal combustion engine, hybrid electric vehicles, motor, engine, regenerative braking, powertrain,
