ABSTRACT
Today automobiles are identified as one of the major causes of air pollution and energy depletion. Vehicles are also identified for their low efficiency in other words high-energy loss. Hybrid Electric Vehicles have the capacity to overcome these situations and bring a new revolution.
Any vehicle that combines two or more sources of power that can directly or indirectly provides propulsion power is a hybrid. The gasoline electric hybrid vehicle is just the required type of crossbreed between a gasoline powered vehicle and electric vehicle. Hybrid vehicles run both with a rechargeable battery as well as gasoline. In a hybrid engine, power from gasoline and power from a set of batteries transmits power to an electric motor. There are less adverse effects due to the Hybrid electric vehicles. Also the batteries used in hybrid vehicles (rechargeable Nickel metal hydride, Lead acid batteries, Lithium Polymer batteries) are disposable which will not pose any toxic hazards to the environment. The notable fact in hybrid vehicles is that the DC machine is that it can run both as a Motor as well as a generator.
In addition, hybrid vehicles make use of a system that recovers power from the momentum of the vehicle when braking. The Hybrid vehicles are complicated machines when compared to their counterparts of the gasoline-powered vehicles. But higher efficiencies, lower emissions of hybrid vehicles grabs the attention of the new ERA. The other facilities of these hybrid vehicles i.e. performance, manufacturing cost and environmental impacts are discussed in this paper...
