I've got my eye on an 85kWh Model S, have my test drive next week, am in research mode. Consumer Reports, in their glowing 99-out-of-100 review of the Model S, said, "To charge more than [halfway] at such speed [at a Supercharger] takes longer and would damage the battery." I asked Tesla Motors sales about this, and the rep said basically Superchargers are spaced 150 miles apart so you should never need to charge more than halfway and for the best life of the battery it's best to save Supercharging for road trips and rely on trickle-charging overnight to keep your battery topped up.
Question for Model S owners: Out there in the wild, if you have been relying on Superchargers for your commute or just taking a lot of Tesla-inspired road trips, do you have any anecdotal data to share on any battery capacity losses noted? In our family's case, we anticipate taking maybe five road trips per year--using Superchargers that often shouldn't permanently cut the battery range, right?
