New initiative from the Competition and Markets Authority:
https://www.gov.uk/government/news/cma-to-examine-electric-vehicle-charging-sector
includes:

The CMA’s work will centre on 2 broad themes:
how to develop a competitive sector while also attracting private investment to help the sector grow
how to ensure people using electric vehicle chargepoints have confidence that they can get the best out of the service


That's probably a good idea. But it still needs consistent messages on taxes and subsidies.

And fines for vehicles "icing" the sockets. (Or EV's not charging)

"The forecourts will offer super-fast wifi, and stand alongside a range of “Best of British” shops including WH Smith and Boots as well as Costa Coffee and the Post Office. Some will offer business meeting pods, a children’s play centre and a “wellbeing area” with exercise bikes that generate electricity."

I've read something in the last couple of days - probably Sunday Telegraph business section - about a proposed chain of electric "filling" stations which would have dynamo-equipped exercise bikes so that customers could contribute to the juice. I didn't look closely but it didn't seem to be a spoof. I imagine the exercise benefits to the pedaller would be greater than the discount of their bill.

Just a bit...

Typical efficiency of EV's is 4 miles per kwh.
An hours cycling by a moderately fit cyclist is probable around 200w (I'd guess half that by an average person who can actually manage to peddle one for an hour).
It'll get you on and off the forecourt providing you're fairly light with the accelerator.

Possibly the Gridserve system as linked in a couple of posts just above?

How about the contribution of solar panels in the forecourt canopy to the energy delivered to the EVs below?

But that fraction doesn't really bother me... we're still at a stage where illustrating what's possible matters.

Yes, perhaps charging at a rate of 1 mile range per hour of fairly high-level exercise. Still, not bad compared with actual cycling, given the mass ratio car:person+bike.

Those solar panels do contribute, not sure you watched the whole of the video (assuming it's the same as the one I posted on another thread) but there's also a field full of panels that provide energy for the forecourt.

Yes, I was requesting the analogous calculation!

So if a moderately fit cyclist does 12mph average, does that mean a cyclist does 16 2/3 W/mi and an EV does 250 W/mi?

So an ebike may be 20W/mi due to the extra weight but probably a higher average speed? I suspect an e-recumbent may be the optimal efficiency, with the motor overcoming the notorious disadvantage on hills.

Don't you want a measure of energy rather than power per mile?

There was a fascinating article suggesting precisely this in one of the HPV journals in the 1980s.
