From what I understand, and the things aren't available here in the USA yet, the stock vehicle can do level 1 and 2 charging out of the box...to get level 3, requires an option.
Level 1 - time for full charge about 8-hours
Level 2 - time for full charge about 3-hours
Level 3 - time for full charge about 30-minutes
Obviously, if your battery isn't discharged all the way, your times should be shorter, maybe a lot shorter.
It would be highly unlikely to have the available power inputs to use a level 3 charger at a typical residence, but level 1 (straight 20A 110vac plug) or level 2 (similar to an electric dryer circuit) are readily available. Most of the public chargers I've seen (and there aren't that many around) are level 2 chargers. The cost for the level 3 chargers is quite a bit higher. I expect more to show up, but they are in the minority, at least in the USA for right now.
