2. 2 Current Industrial Trend A hybrid electric vehicle or HEV is powered by a combination of a gasoline engine and an electric motor. HEVs have desirable environmental benefits: they produce less CO2 and reduced emissions Powered by an electric motor and a battery, EVs are clean vehicles that do not emit any CO2 or exhaust emissions while operating. Reducing Emission
