Driving Green: What are plug-in hybrid (PHEV) cars?

Charging ahead


What is a plug-in hybrid

THE PROBLEM with conventional hybrids is that they rely largely on an internal combustion engine for motive power. One of the selling points has been a hybrid’s ability to run purely on electric power but this was only possible a handful of miles at low speeds

Enter the plug-in hybrid (or PHEV); a car with a larger battery that you could recharge from your home socket to give a much better electric-only range. The result is an electric-only range of more like 30 or 40 miles — probably good enough to get you to work without burning a drop of petrol or diesel.

However, this assumes that you have somewhere convenient to charge your car – and the same applies to E-REVs and pure-electric vehicles. If you have to park your car out on the street, you’ll not be able to trail a charging cable into the house and will need to find public charging points to keep the battery topped up. If you don’t charge up, the efficiency is massively reduced as you’re using your petrol or diesel engine to both move the car and generate electricity for the battery.

If you can charge up easily, there are benefits beyond emitting less pollution: the official CO2 figure will mean the tax man loves you and company car drivers will have massive Benefit in Kind reductions. You will likely be exempt from the London Congestion Charge, too.

In other words, it’s horses for courses: for some a PHEV will be ideal, for others it will be a waste of time.
