A hybrid electric vehicle typically combines the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle
Hybrid electric vehicles of the future could use alternative fuels such as biodiesel, natural gas, or ethanol.
Hybrid electric vehicles are powered by two energy sources – an energy conversion unit and an energy storage device The energy conversion unit can be powered by gasoline, diesel, compressed natural gas, hydrogen, or other fuels.
This hybrid vehicle have the potential to be two to three times more fuel-efficient than conventional vehicles.
A hybrid electric vehicle employs an optimized mix of various components. These include:
- Electric traction motor and controller
- Energy storage systems, including batteries and ultracapacitors
- Power units and transmissions, including spark ignition engines, compression-ignition and direct-injection (diesel) engines, gas turbines, and fuel cells
- Energy management and systems control
Gasoline-electric hybrid cars contain the following parts :
- Gasoline engine
- Fuel tank
- Electric motor
