What is a "range extender"? Another battery? Where do you put it? On
the
back seat?

It's a fossil fuelled engine driving a generator that you use to replace
the power you draw from the battery. A.K.A. a hybrid drive train.

You could, of course, replace the whole drive train with an engine and
gearbox directly driving the wheels, but that's not "green", even when it
used less energy overall than the hybrid.

Maybe it could be fixed using a supercapacitor.

Mounted on the hard shoulder?

In your Tory Pixieland, of course.
