What are BEV, HEV, ICE Vehicles?


If you haven’t heard of these strange acronyms, you aren’t alone, but you should get used to seeing them around as they are the future of our road transport.

With global mandates insisting on the reduction of carbon exhaust emissions and to ensure higher miles per gallon in all vehicles, vehicle manufacturers have developed different power choices today for tomorrow’s vehicles.

With the introduction of electric vehicles and the future looking more environmentally friendly than it has over the past 100 years, now is the time to get used to these terms, which will soon become part of all of our vocabulary…

BEV – Battery Electric Vehicle
Let’s keep this simple – BEV is a battery electric vehicle and is ONLY powered by a battery – there are literally no other ways of making them go.

There’s no running off to the local garage to fill up with diesel or petrol if your battery runs flat.

So, a BEV is a 100% electric car, which makes it the global goal for us all to have one with its zero emissions.

HEV – Hybrid Electric Vehicle
This is a combination of an ICE internal combustion engine, as well as an electric motor, and a battery pack, with regenerative braking and plug-in capability.

But, because this vehicle is a hybrid with both diesel/petrol and a battery, you can’t plug the vehicle in to recharge it.

Okay, we know that sounds crazy, but it’s true.

It’s the best of both worlds.

HEVs are mainly petrol or diesel-run vehicles, and they only have a small battery, which typically helps the vehicle go further and/or it helps improve its performance with its acceleration, for example.

These vehicles can run on the battery alone but often at very low speeds – when it needs to get faster, the petrol or diesel kicks in.

If you are driving an HEV, you’ll hear the petrol /diesel engine running most of the time.
The battery charges itself partly via ‘regenerative braking.’
This works by you pressing on the brake pedal, which makes the electric motor go in reverse and act as a generator. And as a generator, the electric motor can charge the battery. Clever.
So, braking means charging the on-board battery. This is one of the ways how HEVs get around the problem of not being able to plug in to an external battery.
However, HEVs also charge their extremely small batteries by burning petrol or diesel inside their internal combustion engines, which doesn’t exactly make it environmentally friendly.
In reality, therefore, the occasionally self-charging proclamation of the HEVs is a bit misleading…

ICE – Internal Combustion Engine
This term refers specifically to the engine rather than the type of car.
Normal petrol or diesel vehicles have internal engines which are known as combustion engines and which are significant contributors when it comes to air pollution and global warming, which is why the electric car is becoming so popular.
These will slowly be phased out for a healthier, greener world, but in the meantime…
