I would have one in a heartbeat if I was in the market for a $80k luxury sedan - for one I think they look brilliant and there are electric charging stations springing up everywhere, most covered public parking lots now have plug-in charging stations as well as plenty of Tesla superchargers around SoCal. I know everyone lols at California being full of tree-huggers (the number of Priuses is evidence alone) but it's cool to see the electric-vehicle revolution taking place.
My pipedream is sometimes moving to Palm Springs to save $500 a month on rent, and put it towards a Model S with a solar panel charging station - free fuel FTW

You mean a 240v charger that are designed to be installed in homes. That's both models.
240v gives you 3kw or 7kw options. The 11kw and 22kw options both require 400v and are under the 'High Speed Charging' section which is tagged as 'coming 2015' (although I'm not sure which part of it is due in 2015 as the dual charger option within the car can be selected now).
And as Davey said, anything you have installed at home is only available when your at home. Unless you refuse to visit anyone unless they live next to a super charger point, there will be times when a wall socket is your only option.

Realiatically the chargers can never really advance past the 7KW option at home, either. 7KW is a consistent 30A load, the next step being a 50A load. The biggest MCBO i have ever seen is a 63A unit, i guess you could push it to the 11KW with a very large feed, consumer unit and mains supply dependent. (If they were to release a 230/40v model ofc).
Super quick charge times at domestic properties cant happen, we dont have the infrastructure

So the 400v options are realistically for commercial buildings and dedicated charging points, rather than people having them in their garages?

Shock as Glaucus cherry picks yet another theoretical/experimantal/potential stat about electric cars and then states it as if its standard technology available to everyone.
Looking at Jez's figures your looking at 15+ hours for a full charge at home, at least.

Yeah 3 phase supply essentially.

From speaking to the sales guy here, he mentioned that the Fast Charge Points would be 3 phase, so commercial/industrial units typically, as getting that installed in a private property would be a nightmare. However you can pay to get a higher output socket at home (can't remember the figures right now). They're everywhere over here - but then again BC is known for being typically "green", so it figures that they'd be popular.
Soldato
For the 400V systems you need a 3 phase supply which is a commercial type of supply which is extremely rare to see in a domestic environment. A couple of my friends run an electrical contracting firm and mentioned that they came across one once, but this was at a very (very) large home set in hundreds of acres.
If we take my little village, my house among my neighbours (the only other houses immediately around, 8 other properties) are fed from the 33KV overhead by a pole mounted single phase transformer. Not only does this mean that none of us can order 3 phase anyway, i bet the transformer is only around 200KVA anyway.
Imagine if we all tried charging our electric cars at once
I bet the situation is really bad in denser areas.The 3kw and 7kw options are using a specially installed Type 2 wall socket. I don't know what you would get with just a standard 3 pin outlet?
Soldato
16A usually with a 3 pin?
3kw will give you about 11 miles range per hour, so Daveys original 36 hour charge time isn't far from the mark.
So realistically from a home charger only your daily range is limited to what you can charge over night, which looks to be only about 100 miles.
Without a 400v charger or a supercharger available to you at atleast one end of your journies your limited to a rather short distance.

It really depends on who buys the car. If you have a 250 mile round trip daily commute, the car isn't for you. Overnight charging is best bet, and you'll get most of your battery charged on a 7kW charger.
The sneaky thing is the car doesn't tell you how long it is to full charge when it's more than 24hrs left to full battery.
The Tesla site was very good for helping calculate charge times, as you could select type of plug and type of charger, but I think they've removed the 13A plug from the calculator.

I think the sales strength of these cars may lie in company car schemes, where the companies can afford to supply charging points at the workplace along with reducing the company's carbon footprint.
Hence my original comment that was beaten down so rapidly. If I did a 250 round trip commute this would be the type of car I would like to do it in (I.e. a luxobarge). But the electric motor means you can't.
While a significant investment for the company, which may put a lot off, this is the way to push sales.
