Design and material characteristics of hybrid electric vehicle

The environmental pollution has turn into a serious problem in the country, especially in countries
where urbanization lead to crowded atmosphere with stuck traffic in the road. Very big amount of
pollutants are emitted from the vehicles day by day. Engineers initiated to monitor various
technologies to deal with the pollution issues. The electric vehicles (EV) are enable full consumption of
energy and produce almost zero emission. Hybrid power system is conceived to give back forunderperformance in the battery. A HEV consists of I.C engine vehicle with battery and electric motor.The benefits of HEVs comprise good fuel economy and less emission. The natural flexibility of HEVs
will permit them to be utilized in wide range of applications. A HEV provides increased fuel efficiency
and emissions are decreased. HEVs can minimize dependence on fossil fuels. Global automobile giantare research and developing the concept HEVs.
