Thats the opposite side of EV. With that little battery capacity like Nissan leaf or the iMiev, your are very depending on a working and dense infrastructure based on DC. With faster AC-onboard charger your are less depend. You charge where you are and as long as you can.

a 1750 mile trip around the UK in a Leaf is expected to take place in September...Originally Posted by Kevin Sharpe
"I want to take my Nissan Leaf around Britain. I have to use existing charging infrastructure so it makes sense to visit all the Nissan Leaf dealers where the majority of fast chargers currently are."

while I have no concerns about the reliability of the ZCW Charging Stations that are being used on the trip, I will be very surprised if all of the DC Chargers are working and think this will generate very negative mainstream press if the trip fails...

fully agree and we have postponed the purchase of Leaf's for my Company's until the 2013 model arrives with improved AC Charging that allows reasonable opportunity charging (something I'm doing today at 32A during a company meeting at a hotel).

i am going to accompany TRON on his challenge "to go east". its really boring to charge on a 32A socket and you know, you could cut charging time to a third if you could do 3-phase charging or at least to half the time if you could convert 3-phase to single phase, high current. Its not the problem through the night, there we can fill up from empty to full within 8hour on 32A, but on a daybreak - you only can do an extended sightseeing, while charging. Therefore you go quite slow, enjoying the ride, get new distance record or new "lowest consumption records" to reach the next hotel where you can have the next full charge through the night.

P.S. It's not just Europe that has domestic 3 phase. The feed to my house in Hong Kong is 3x400amp. Limit is the circuit breaker, meter and MCB.
I used to have 3x60Amp for that, and recently upgraded to 3x150amp to be able to install a 70amp Tesla HPC on one of the phases - not ideal. Something like 3x16amp could easily have been done without upgrade and would have been more balanced to (easier on) the grid,
This is residential. There are about twenty houses around me, and they all have individual 3x400amp feeds. High rise apartments here are usually 3x60amp.

Ok, this is what I've learned tonight from the Model S event at the factory.
As you might have seen in other threads there is going to be a new, Tesla-only connector for charging a Model S, no standard J1772 or "Mennekes" connector.
I've poked around a bit about the three-phase charging and it will NOT be available at this time. I stressed it enough to the power-train designer (forgot his name) that as a European lack of three-phase could really be a dealbreaker.
I absolutely love the Model S! It's a gorgeous vehicle with so many goodies and stuff, I really, really, really like it, but the lack of 3-phase gave the event a bit of a bad taste for me (personally).
The feeling I got is that Tesla still believes in their own propriety connector and charging at home. The argument for not having 3-phase support in the car was "The battery is so big, you don't need to charge that much", rubbish to me..
Anyway, the connector they've come up with will handle AC and DC over the same connector and pins, they said nothing currently available could do that. I pointed him to Mennekes and he turned away from that.
I tried to stress him that lacking three-phase you'll be limited to 16A (80%) or 32A (20%) most of the time. With that huge 90kWh battery that simply sucks. Charging times of about 15 hours on 32A.
I didn't get a promise from him, but after talking for a while he said "We'll come up with something that works, we have more then a year to go", we shook hands that and I left.
The current status is that the Model S does currently not have 3-phase support, it does however support DC. With a converter it should be able to connect to CHaDEMO chargers.
They will look into the three-phase charging again and come up with something. I told him it should be portable, not a small DC charger for home, since all European charging stations have three-phase.
I'm really thinking about writing a good letter to Tesla which we should all sign to emphasize it again to them: Europeans don't want three-phase charging, they NEED it
Other than that, I really do like the Model S, what a beautiful car!
Some might. I don't care about it, no three-phase charging stations exist in Norway and 16A single phase is enough for home charging for us. CHAdeMO is a must though, did they promise CHAdeMO would work or is that your guess ? Lack of CHAdeMO charging would be a definite deal breaker for me, without it the Leaf will have the longer range in a day and be more suited to road trips...
It's only a matter of time before they arrive in Norway. There are now dozens in the UK.
@widodh I'll sign your letter to Tesla emphasising the NEED (not want) for 3-phase and CHAdeMO Model S charging in Europe
No plans so far at least. Everything that is getting installed now is either 16A single phase or CHAdeMO. Most of the country does not have access to 400V three-phase either, just 230V three-phase which probably won't be supported by the car manufacturers as only Norway and Albania use that system (IT distribution grid, not TN like the rest of Europe).
