Hybrid vehicles have become increasingly popular in Australia due to their fuel efficiency and reduced environmental impact. There are several types of hybrid vehicles, each with unique characteristics and operational mechanisms. This article will explore the main types of hybrids available in Australia: Mild Hybrids, Full Hybrids, Plug-in Hybrids, and Range- Extended Electric Vehicles.
Mild Hybrids (MHEV)
How They Work:
Mild Hybrid Electric Vehicles (MHEVs) use a small electric motor to assist the internal combustion engine (ICE). The electric motor cannot power the vehicle on its own but provides support during acceleration and can help with regenerative braking.
Key Features:
Electric Motor Assistance: The electric motor assists the ICE during acceleration, improving fuel efficiency and reducing emissions.
Regenerative Braking: Captures energy during braking and stores it in a small battery.
Start-Stop System: Automatically shuts off the engine when the vehicle is stationary and restarts it when needed.
Example Models:
- Suzuki Swift Hybrid
- Mazda3 M Hybrid
Full Hybrids (HEV)
How They Work:
Full Hybrid Electric Vehicles (HEVs) can operate using the internal combustion engine, the electric motor, or a combination of both. The vehicle can switch seamlessly between the power sources to optimise efficiency.
Key Features:
Dual Power Sources: Can run on electric power alone for short distances, ICE alone, or a combination of both.
Regenerative Braking: Captures and stores energy during braking.
Battery Charging: The battery is charged through regenerative braking and the ICE.
Example Models:
- Toyota Prius and Camry
Plug-in Hybrids (PHEV)
How They Work:
Plug-in Hybrid Electric Vehicles (PHEVs) have larger batteries compared to HEVs and can be charged via an external power source. They can travel longer distances on electric power alone before the ICE is needed.
Key Features:
Extended Electric Range: Can travel significant distances on electric power alone, typically between 30 to 60 kilometres.
External Charging: Can be plugged into a standard electrical outlet or a dedicated charging station.
Dual Power Sources: Similar to HEVs, they can operate on electric power, ICE, or a combination of both.
Example Models:
- Mitsubishi Outlander PHEV
- BMW 330e
Range-Extended Electric Vehicles (REEV)
How They Work:
Range-Extended Electric Vehicles (REEVs) primarily operate as electric vehicles but include a small ICE that acts as a generator to recharge the battery when it depletes. The ICE does not directly drive the wheels.
Key Features:
Primary Electric Operation: The vehicle is primarily powered by an electric motor.
Range Extender: A small ICE generates electricity to recharge the battery, extending the vehicle’s range.
No Direct ICE Drive: The ICE does not directly power the wheels, only recharges the battery.
Example Models:
- BMW i3 Rex
- Holden Volt
Conclusion
Hybrid vehicles offer a range of options to suit different driving needs and preferences. Mild Hybrids provide a modest improvement in fuel efficiency, Full Hybrids offer greater flexibility with dual power sources, Plug-in Hybrids allow for extended electric-only driving, and Range-Extended Electric Vehicles provide the benefits of electric driving with the reassurance of an extended range. Understanding these differences can help Australian drivers choose the hybrid vehicle that best meets their needs.
