How many of you reckoned we'd make it to Scotch Corner then? Not many, I suspect - and nor did we, frankly.

On our way north in BMW's electric Mini, Sheffield proved too far as a stopover. At constant speed on the motorway, the Mini quickly runs out of power. With no brake energy regeneration to top it up, it actually burns through battery charge faster than the car's remaining range predictor can allow for.

That meant diverting to Nottingham, to the Victoria shopping centre, where Elektromotive - the company responsible for most of the on-street charging points you see around London - has a number of 13 amp charging posts. We were lucky to find one next to an empty parking bay; the one next to it was rendered inaccessible by a badly parked C-class. Note to car park operators: if you're going to bother with charging posts, make the parking bays next to them EV-only
