How It Works section at Popular Science online
One of my gripes about news features on new electric cars is that they frequently give the milage per full charge, but not the energy content per charge. So it is impossible to do a cost comparison with a gasoline or Diesel car. We need to know how many kilowatt hours (or Joules) per charge. If I know my electric rate (it appears each month on my electric bill) I can see how much a full charge costs me. I know what I pay for fuel (or play "what if" games) so can compare with a high gas milage gasoline car. But without knowing how much electricity a full charge represents, it is impossible to do the comparison.
At BEST they will tell how long they take to charge... and you can assume that they charge off a 20A 120V feed... but that isn't always a good assumption.
