Sorry, I'm lost. P=I*V, what am I missing?
Nothing. Doug is.
All this is OT though really. I’m sure that EV charging efficiency has some range, depending on the supply charger, the EV’s on board charger, charge cord gauge and length, etc, etc. A range of 85 - 95% is probably reasonable. That’s really pretty good.
In the end it makes little difference to the bottom line - which is that “payback” on any price premium (if there even is one) for any BEV or PHEV is going to at worst take 5-10 years depending on miles driven, gasoline/diesel vs electricity prices, etc. And in many cases payback will be nil or occur in just a couple of years.
And of course cost is just one of many considerations. Some may try to deny it but we ALL make choices in our purchases based on factors other tham cost alone, which is why very few cars on the road are the cheapest most basic needed just to move people from A to B.
The transition to EVs is occurring whether some like it or not. When they will compromise a majority of cars on the road is anyone’s guess. I’d guess it will happen 15-20 years from now IF society as a whole can continue to hold together (a big if IMO).
