Paul,
I see you've made some changes but you've also introduced some other mistakes:
"Opting for a Level II 220-volt charger will typically trim the charge time down by at least half.* Depending on the amperage of the charging system, that can bring charging times down significantly.* Ford’s 7.5-amp Level II charger for the upcoming Focus Electric is expected to trim times down to just 3.5 hours, about half the time required to recharge Leaf using its lower-amperage system."
Ford's charger may be 7.5 kW but it sure as hell isn't 7.5 A.
The problem that I and clearly many others have is with this:
"The larger Model S, with its huge 300-mile battery, would, at best require about 14 hours to get back on the road – at best.* A lower-amperage charger would keep the sedan tethered for a day or more.* That is, unless an owner were ready to head out on only a partial charge.* But, at that point, what would justify paying the huge price premium for the extra kilowatt-hours?"
We've shown unequivocally that your use of the phrase "at best" in this paragraph is wrong. You've resorted to arguments about people having to upgrade their domestic electricity service, which may or may not be true on a case by case basis, but it doesn't take away from the fact that 14 hours is not the "at best" scenario that someone buying a Model S can expect. In fact, it's not even the second best because, as the others have pointed out, with a cheap NEMA 14-50 one can still comfortably charge the car in around 9 hours.
You are getting feedback from multiple experienced Roadster drivers. I'd take that as a good thing. All we are asking for is the flawed 14 hour premise to be corrected.
