Plug-in hybrid electric vehicles are the combination of an electric motor and an internal combustion engine. They can run in electric-only mode, gasoline-only mode, or a combination of both. For shorter trips, you can operate in power mode, and you can switch to gasoline mode for longer trips. This dual-power source increases overall efficiency and reduces range anxiety. Such vehicles run on gasoline when the battery is depleted. These EVs have a smaller battery capacity compared to battery-electric vehicles. The range of PHEVs is not higher, but their charging time is shorter than that of battery-electric vehicles because of their small battery capacity.

The internal combustion engine, electric motor, battery pack, inverter, control module, drive train, fuel tank, charge port, and exhaust system are the components of plug-in hybrid EVs.

The Volvo XC90 Recharge, BMW 7 Series, Porsche Cayenne, and Toyota RAV4 are examples of plug-in hybrid electric vehicles.

3. Hybrid Electric Vehicles:

Hybrid electric vehicles have an internal combustion engine with an electric motor. Like plug-in hybrid electric vehicles, HEVs cannot be plugged in to charge the battery, but the battery is charged through regenerative braking. Such vehicles have a limited electric range but are more fuel-efficient than gasoline vehicles.

The components of hybrid EVs are the internal combustion engine, electric motor, battery pack, inverter, control module, drive train, fuel tank, and charge port.

The Toyota Prius, Honda City eHEV, Maruti Suzuki Grand Vitara, Volvo X690, MG Hector, Toyota Camry, etc. are examples of hybrid EVs.

4. Fuel Cell Electric Vehicles (FCEVs):

FCEVs are known as fuel cell vehicles. It is another type of EVs that uses hydrogen cells to generate electricity, which powers an electric motor. FCEVs emit only water vapour. They offer a longer range compared to other vehicles but face challenges related to hydrogen infrastructure availability.

Fuel cell electric vehicles need hydrogen fuel, stored in the fuel tank. In the fuel cell stack, the hydrogen fuel is converted into electricity, which helps to charge the battery.

The components of fuel cell EVs are the battery pack, electric motors, inverter, control module, drive train, fuel cell stack, and fuel tank.

The Hyundai Tucson, Toyota Mirai, Hyundai Nuxo, and Honda Clarity are the best examples of fuel-cell EVs
