As a percentage of the cost of a new EV, I doubt they are that

what is going to cost money is installing the infrastructure needed to
power them.

I think that may be over estimated. All the houses here already have an 80
amp supply. No restrictions via the main feeders on how much you use of
that in practice. And peak demand - cooking etc - is likely to be at the
same sort of times. So charging a car overnight may well not overload the
feeders. It's not as if everyone will need to charge every car from empty
to full every single day.

I was thinking of the infra-structure needed for supplies at the edge of
the road for those who park there.

I think that would never happen. If you look at where those cars get
driven, apart from the school run, almost all of them end up in public
car parks at the supermarket, or in a town centre for visits to the
shops. Those are ideal locations for charging stations.

I really dont think charging is ultimately a barrier to BEVs - it's a
matter of money only, and already batteries that can fully recharge in
under ten minutes, given a big enough current, are feasible., What is
unacceptable is having only a 210 mile range and the need to go miles
out of your way - increasing journey lengths and times - to find a
charge station.

And what is even more unacceptable is having their use legislated by
diktat from Princess NutNuts and her ilk.

Looking at the use of current cars what is needed is 600 mile range, -
which implies something like a 250kWh battery - so that charging
overnight during the week, at home, or even at a local supermarket or
charge station within reasonable walking distance, nets you a once a
week long trip to see granny etc. without need to 'refuel'

The problem is that currently that would weigh and cost more than the
rest of the car put together by a considerable margin.
