Plug-in hybrid (PHEV) and regenerative hybrid are terms that are sometimes used interchangeably, but they refer to different aspects of hybrid technology. Let's clarify the differences:
1. Plug-In Hybrid (PHEV)
A plug-in hybrid (PHEV) is a type of hybrid vehicle that can be charged from an external power source, usually an electrical outlet.
PHEVs have larger battery capacity compared to regular hybrids, allowing them to travel longer distances on electric power alone. The internal combustion engine in a PHEV serves as a backup power source for when the battery is depleted.
Certain PHEVs currently qualify for the Australian Government Electric Car Discount, making them more affordable for Australians and the ability to run them 100% pre-tax.
Key features of PHEVs include:
- Electric Range: PHEVs can typically travel a certain distance (electric range) solely on electric power before the internal combustion engine needs to engage.
- Charging: PHEVs can be plugged into charging stations to recharge their batteries, providing the option to operate with reduced or zero emissions during short trips.
- Fuel Efficiency: PHEVs offer improved fuel efficiency compared to traditional internal combustion engine vehicles since they can use electric power for a portion of their trips.
Popular examples of PHEVs in Australia include:
MG HS+ EV
Available from: $48,690
Mitsubishi Eclipse Cross PHEV
Available from: $47,290
2. Conventional/Regenerative Hybrid
Regenerative hybrid refers to a specific technology within hybrid vehicles that allows them to capture and store energy that is normally lost during braking or deceleration.
This energy is converted into electricity and stored in the vehicle's battery for later use. This technology is present in various types of hybrids, including both regular hybrids and PHEVs.
Key points about regenerative hybrid systems include:
- Regenerative Braking: When the driver applies the brakes to decelerate, the electric motor in the hybrid vehicle acts as a generator, converting kinetic energy into electricity and storing it in the battery.
- Efficiency Improvement: By capturing and utilizing energy that would otherwise be wasted as heat during braking, regenerative hybrids improve overall energy efficiency and reduce wear on the traditional braking system.
In summary, while plug-in hybrids (PHEVs) focus on the ability to charge from an external source and travel longer distances on electric power; regenerative hybrids emphasize the capture and reuse of energy during braking and deceleration to enhance overall efficiency.
It's important to note that these types of hybrid technologies are not mutually exclusive; a plug-in hybrid can also utilize regenerative braking to maximize energy recapture and efficiency.
Popular examples of regenerative hybrids in Australia include:
Toyota Corolla Hybrid
Available from $27,395
Toyota RAV4 Hybrid
Available from: $36,800
