Anyone have Model S charging information?

I did a search on Tesla Model S charging white papers and all I came up with was press release related information on Tesla's Superchargers.

My Zero has an on board 1kw charger that charges the battery at 1/9C (9kw battery). It accepts 110 or 220V via a standard (high current) IEC printer type power cord. The 2013 models will also accept a CHAdeMO high speed charger. The Zero's battery is around 65V fully charged so the charger is a simple rectifier (AC to DC) regulator combination. The Model S seems to have a lot more going on.

I ordered my S with two on board 10kw chargers. There seems to be a few cord options (wall chargers) and the Supercharger route. Can someone shed some light on what happens between 110V, 220V and Superchargers and the battery with the Model S? My assumption is that all batteries have the same fully charged voltage and that capacity is determined by the number of cell sets in parallel. So, some of my questions would be-

The Model S comes with a Mobile Connector. Is this a simple direct cord from my wall outlet to the plug under the brake light lens?
I ordered the twin chargers which I assume takes the car from having one 10kw charger to two of them on board. Is this correct?
What is the High Power Wall Connector? I ask because $1200 would indicate it is something more than a simple cable from the wall to the car.
Is the connector under the brake lens the only charging connector on the car or does the Supercharger use a different connector?
Does the Supercharger supply high voltage current limited DC directly to the battery bypassing the on board chargers (be they one or two)?
What is the battery voltage of a fully charged battery?
Is the Supercharger supply under the direct supervision and direction of an on board battery management system?

Thanks for helping to fill in these gaps for me

Nickjhowe and Jat: Thank you.
I managed to find the 30 ft 50 Amp Nema 14-50 extension cord on Amazon, brand is Camco. I cannot find the adapters, which is probably why you made yours (looks beautiful). I am not motivated enough to learn to make my own. This is the closest I can find which looks like 10-30 on the male end. Can't find 14-30 adapter non locking kind. http://www.camco.net/Products/Item?prodID=10229

@Hills - note that if you are going to make a 10-30 adapter, it is tricky. That is an ungrounded connector, and has the two hot phases and neutral. The 14-* series of connectors also has ground, and the Model S requires the two hot phases and ground and does not need neutral as it has no 120V loads. Neutral is bonded to ground at the main panel, and isn't supposed to be bonded anywhere else. So, you can route neutral from the 10-30 plug to ground on the 14-50 receptacle, but make sure you never ever use this for anything but charging the Model S as it is ungrounded.

@Hills - note that the Camco adapter is not NEMA 10-30, but instead a 120V plug (the 10-30 has an L-shape neutral pin, while the adapter above uses a rounded ground pin) that is a TT-30. You do not want this adapter, unless you happen to need to charge off a TT-30 receptacle.

Making an adapter should be a simple matter. The last time I was at my local Ace hardware store I saw 14-30 dryer cords right next to female 14-50 connectors. Both were around $10-12 each. I also found some adapters that are nicely molded and not very expensive on Amazon. I already got a nicely molded 10-30 to 14-50 adapter for around $20.

I also ordered a 10 gauge 100ft extension cord since I plan on driving up to Lake Tahoe. The place I'm staying at says they have 115v outlets but not next to the parking spaces. 10 gauge is suitable for 30A (24A continuous) though this would limit it to 12A. I figure with 10 gauge there will be a lot less loss compared to a 12 gauge extension cord. It's too bad that we can't up the current to 16A if we plug into a 20A 115v outlet since those are also rather common.

@aaronw2
Would you share the link to the Amazon adapter you bought? I can't find it.

Here is the NEMA 14-50 50 Amp 30' extension cord I found,

@aaronw2 - someone did make an adapter from a NEMA 6-20 plug (20A@120V) to a NEMA 14-50 receptacle -- the mobile connector seems to be autoranging and will happily accept 120V even though the adapter is for 240V. You will still have to manually adjust the car to 16A though.

@Hills - that extension cord should be ok. When you first use it, check it every so often to make sure it doesn't get too hot to hold.
