Hybrid gasoline-electric vehicles use a combination of recyclable batteries and fossil fuel. They are a step in the right direction while we wait for driving range and ease of recharging to catch up. Meanwhile, mild hybrid vehicles are providing a middle ground, an intermediary step if you like. Although we may be surprised to discover this facility has been around for longer than we thought.
Levels of Mild Hybrid Vehicles Available Right Now
A hybrid electric vehicle uses gasoline as its primary propellant, with ancillary electrical support it can activate as required. The extent of the latter varies across a spectrum, as we shall see:
- Ultra-mild hybrids have been using batteries and electric self-starters since 1911, to crank combustion engines until their motion becomes self-sustaining.
- Mild hybrid vehicles extend this facility to include operating a vehicle’s secondary electrical systems, and providing additional torque during acceleration.
Full or standard hybrids, on the other hand have an alternative electric drivetrain that can take over from the gasoline one, and propel the vehicle for short distances. And then, finally we come to plug-in hybrids with more powerful batteries and driving ranges up to 50 miles. We have wandered slightly off track. It is time to get back to our topic!
Should We Bother Ourselves with the Mild Version?
We pay a bit extra for a mild hybrid car. However, once we have one we need do little more. That’s because it recharges itself through the green power of regenerative braking. This system harvests the energy, and feeds it through to the mild hybrid battery. But the system has a few more tricks up its sleeve:
- Many mild hybrid vehicles automatically boost the gasoline engine’s power during accelerating, including when overtaking.
- They may also be able to take over from the engine completely when coasting, lowering carbon emissions slightly.
However, perhaps these mild vehicles’ greatest contribution is acting as a bridge to full-electric driving. As first-time owners come to realize that electric auto power is not a joke, because it is the only renewable way to remove carbon emissions from our highways.
