What is a range extender? And can I buy an aftermarket one?

What’s a Range Extender?

Not something that makes your wifi powerful enough for the whole street to abuse, but a battery-electric vehicle (BEV) paired up with… fossil fuels.

Wait, what? How the heck does that work?

Because the electric motor drives the axle from a battery, this is an electric car. But there’s an on-board petrol-drinking generator that can recharge the battery once it’s depleted, hence the ‘range-extending’ title.
