Various threads have speculated what charging options will come standard with Model S and what you would be available separately. We don't know for sure yet, but I will start off with some speculation just based on semi-educated guesses of what they might do, for North America: Standard: 10kW on-board 1-phase charger with UMC2 including NEMA5-15 ([email protected]) and NEMA14-50 ([email protected]) plug adapters that snap in to the end of the UMC2 cable. J1772 adapter module that plugs directly into the Model S Tesla proprietary charge socket for public charging. (No need to use the UMC2 for this.) Included DC quick charge capability for public Tesla 90kW DC "superchargers". Optional: Extra plug end adapter modules for the UMC2... Various Dryer/Stove outlet types, etc. 20kW ([email protected]) HPC2 for home / garage charging. 2nd in-car 10kW charger for 20kW total rate AC charging from HPC2 and high current J1772s. (without this upgrade, the HPC2 would be no quicker than the UMC2.) Old style (Roadster) adapter so that older UMC1 and HPC1 can plug into Model S... (?) <== (I am surprised this hasn't been discussed too much yet.) Uncertain: Adapters to non-Tesla DC quick chargers - CHAdeMO, SAE, etc. Some people seem to assume that UMC1/HPC1/Roadster cable to new style, and CHAdeMO to new style would be a "given", but I am not so sure. I got no comment/commitment on either when asking about the possibility at the factory tour. If anything they seemed to be suggesting that CHAdeMO adapters wouldn't happen. Europe could be a different situation... Please leave all the "we need 3 phase" talk in those other threads.
