Re: 50 miles???
"My statement was that there is plenty of capacity at night that is why the electricity is cheap in off peak"
hmmm - yes, if you have a dual rate meter, you get a cheaper rate at night.
however, as I was told just last week by the electricity company, the current crop of "smart" meters, are not compatible with dual rate electricity tariffs.
and by the way, some of us regularly travel 300 miles plus (round trips of 400 miles are not uncommon for me, with an average annual mileage of over 20k miles. My daily commute is 60 miles), have no way to charge an EV at home (I live 3 floors up in a flat, and there are no charging points on my street) - charging would require me to go to the local train station, and wait an hour or two to charge, before coming home.
I would also like to remind you that a large % of the population live or work in cities - with vast numbers of cars parked on the roadside. if you drive to work, and park in a city, you will need a charging point at the parking spot, or you will need to rely on there being sufficient charge left to get home - assuming you can charge at home.
and finally, something that nobody seems to want to think about. crime. theft of electrical cable is relatively common. all of those cars that will be charging on streets, will have quite hefty chunks of cable attaching them to the chargers. I have never noticed any method of locking the cables in place (and a determined thief would simply cut the cable to steal it). your car is not going to charge very well overnight if the cable goes walkies. and how about the anti-social yobs that cause damage just for the fun - cars already get scratched and destroyed by them - imagine the fun they could have with a tube of superglue and all those charging points..............................
