>“If the wondercar got 40 mpg, it would burn 5 gallons of gas to go 200 miles, at a cost of $15. 1 gallon is 35 KWH of electricity, cars are 13% efficient (on average) so the amount of electricity at the tire to do the same work is 197 KWH, which around here would cost .12 per KWH or about 23 bucks.”
Your calculator dropped a decimal point - that is 19.7 KWH and $2.30.
It was someone elses calc. Good catch. Now when I check it, I’m coming up with 22.75K..
Do you have any clue how to estimate the efficiency/loss from battery charge to tire?
