There are 3 types of electric vehicles:
Battery Electric Vehicles (BEVs) are “pure electric vehicles” that operate on electric power only. They have electric motors fed by batteries that must be plugged in to an external electrical source to charge. They typically have a mileage range of 100-200 miles. All-Electric motors convert 75% of the chemical energy from the batteries to power the wheels, while internal combustion engines only convert 20% of the energy stored in gasoline.
Plug-In Hybrid Electric Vehicles (PHEVs) has both an internal combustion engine and an electric motor that uses rechargeable batteries or another storage device that are charged by plugging into an external power source. They are sometimes referred to as “extended range electric vehicles” or EREVs, and have a mileage range of 30 to 40 miles on electric power before they use fuel.
Hybrid Electric Vehicles (HEVs) combine an internal combustion engine propulsion system with an electric propulsion system that is not charged externally. The electric motor can boost the driving range of an HEV to over 600 miles on a tank of gasoline, which results in lowering pollutants.
