answer:

There are four types of electric vehicles available:

• Battery Electric Vehicle (BEV):Fully powered by electricity. These are more efficient compared to hybrid and plug-in hybrids.
• Hybrid Electric Vehicle:
  • Hybrid Electric Vehicle (HEV): The vehicle uses both the internal combustion (usually petrol) engine and the battery-powered motor powertrain. The petrol engine is used both to drive and charge when the battery is empty. These vehicles are not as efficient as fully electric or plug-in hybrid vehicles.
  • Plug-in Hybrid Electric Vehicle (PHEV): Uses both an internal combustion engine and a battery charged from an external socket (they have a plug). This means the vehicle’s battery can be charged with electricity rather than the engine. PHEVs are more efficient than HEVs but less efficient than BEVs.
• Fuel Cell Electric Vehicle (FCEV):Electric energy is produced from chemical energy. For example, a hydrogen FCEV.

Battery Electric Vehicles (BEVs)

Battery electric vehicles (BEVs)—also referred to as “all-electric vehicles”—run on electricity only and are recharged from an external power source. They are propelled by one or more electric motors powered by rechargeable battery packs

Plug-In Hybrid Electric Vehicles (PHEVs)

Plug-in hybrid electric vehicles (PHEVs) also use batteries to power an electric motor and can be recharged from an external power source, but they incorporate a smaller internal combustion engine that can recharge the battery (or in some models, directly power the wheels) to allow for longer driving ranges.

Hybrid Electric Vehicles (HEVs)

Hybrid electric vehicles (HEVs) are powered by a combination of an internal combustion engine with electric motors running off a battery pack for greater efficiency. The batteries of an HEV cannot be recharged from an external source.

Fuel Cell Electric Vehicles (FCEVs)

Fuel cell electric vehicles (FCEVs) use a highly efficient electrochemical process to convert hydrogen into electricity, which powers an electric motor. FCEVs on the market today are not designed for recharging their battery from an external source. Rather, they are fueled with compressed hydrogen gas that is stored in a tank on the vehicle.
