had an email exchange with Tesla this morning about the Chademo adaptor, below is a cut and paste from their response

For the time being, there are no development regardinh the ChaDemo adaptor.

No other information but though may be useful for those buying a Model S in the UK or considering one.

No idea, but I like that shade of white.

I wonder what the weight of the adapter and CHAdeMO plug is compared to a few extra feet of high-current cable?

We can hope Tesla thought this though and reinforced the vehicle charge port.

the charge port has some play in it, so anyone wiggling the cable does not damage the connector, so I suspect its fine. The reason I believe the adaptor is taking so long is that its undergoing extensive field trials all over Europe

Why should Tesla owners get to have a.Chademo adaptor? No really you have the expanding super charger network, surely this should be your means of charging.

If this is happening there should be an adaptor for a super charge to CHAdeMO, honestly it should work both ways!!!

As a non Tesla owner it seems you're all having your cake and eating it.

Don't feel bad @IanT , I own a model S, but can't use the Superchargers either. Remember it costs £1800, for this "free" charging. It's just wrapped into the price of an S85.

Those on finance deals will have paid 57% of that figure over 3 years, or £1026, If they take up Tesla's residual guarantee and hand their keys back....

That's a lot of home charging

I don't need the convenience, if and very rarely when, I need to do more than 180 miles in a day, I'll take the ICE.

If you pay the £1,800 access fee, design build and test a working adaptor, and work with Tesla to get it approved I'm sure it's possible. Bear in mind though superchargers are so far apart only the outlander can get between them, and it's restricted to about 20kw charge rate, not making much use of the 135kw available from the supercharger.

I'm only commenting on the UK, but I guess the difference is that the CHAdeMO charge points are for public use and therefore everybody has equal rights to use them. You have Nissan, Mitsubuishi, Citroen etc. however the Tesla Superchargers have been funded entirely by Tesla themselves. Additionally it uses the same Type 2 plug/socket to deliver 120kW which no other car can get close to.

They seem totally open to working with other manufacturers so if you have a gripe, it should be aimed at Nissan, Mitsubuishi, BMW etc for not working with Tesla to use their technology. All their cars can receive DC charging but with the systems out there they are compatible with, 50kW seems to be the maximum. Once there are bigger batteries in their cars like Tesla then they can probably receive higher charge rates and then hopefully the CHAdeMO/CCS will be pushed further so they still give a 30min recharge time....

From an entirely selfish point of view, a Model S will charge far faster on CHAdeMO . I'd rather see them charge up and leave instead of hogging.
As things are now, a Model S can take over three hours to charge on the AC side of a Type-2/CHAdeMO rapid.

The Ecotricity network is public. While the initial batch of chargers were mostly (entirely?) privately funded, the 74 RCN chargers are partially EU funded. It would be wrong to ban one make of car from public rapid chargers.

In a perfect world, there would be a single EV charge connector, more then enough rapids, and everyone would play nice together.

In the UK there is a hard limit on the amount of power available at motorway services. Ecotricity got there first and is willing to share. Tesla's heavy handed attempt at world domination failed.

Ecotricity has requested everyone observe a 30-minute limit at busy rapids. Why limit Tesla owners to ~11kW when they could get ~25kW with the Chademo adapter?

If a tesla owner is paying (in the future) to use elec highway they will be the same as any other customer...

It shouldn't matter who uses the electric highway now as long as everyone abides by the etiquette recently posted by Ecotricity i.e. make way for the next person after 30 mins.

That's not what it says

Electric Highway rapid chargers are designed to do exactly that – deliver a rapid charge – in no longer than 30 minutes...charge up and let someone else use it.

It's pretty darned close. I would take it as Rapid = park-up, plug-in,bugger-off in "rapid" succession.

But currently elec highway is operating in 'utopia' mode. No time limit, no cost, and a small (relative) user base.

The jury is still out. Let's wait until next year.

The default setting on the rapids I've used end the charge after 45minutes. Of course they can be changed or just restarted.

I would have thought Leaf drivers would be happy to see this, it will mean less "hogging" of chargers, in theory a model S should be able to add 70 miles in 30 mins thats twice as fast as the AC side, so in theory they will be done and free up the charger quicker.

I think it is:

Hog a charger...charge up and move on
Electric Highway rapid chargers are designed to do exactly that – deliver a rapid charge – in no longer than 30 minutes...charge up and let someone else use it.

This was reiterated by a Tweet from Ecotricity as well.

Still no official date for when the adapter will be available?

I can understand the frustration of seeing the 50kW 125A in Waitrose car park and not being able to tap into it all that juice. So near and yet so far.

Don't forget that I have yet to hear of any of the Electric Highway chargers delivering more than about 42kW. Everyone is talking about 50kW... that is what is advertised but the reality seems to be 42kW (396V / 106A).

It is a small point I know but it is worth remembering that it is unlikely, at this charge rate, that any car will get more than about 20kWh in 30 mins and probably less as the charge rate ramps down.

I'd love to know why the charge rate is limited to 42kW... another thread perhaps
