It is pretty standard in most electric cars I've been in that it shows the kWh/h as it charges and how many kWh it has charged when complete.

Also your comment reminds me of the Boots economic theory. That poor people pay more overall because keep buying cheap boots yearly rather than spend more once on expensive boots every 10 years like the rich.

A captured government is the problem, the corrupt administration and the purchased opposition can't do anything for you like cheap power and subsidized electric cars because it doesn't help their donors.
