100thMonkey it would sure be nice if I could go gallivanting about in WA and Oregon, demonstrating the speed and ease at which the S can handle long trips... but for lack of a CHAdeMO adapter, I'd have to drive my S like a Leaf and sit for long periods, only adding to the bad press. we've got CHAdeMO every 25-40 miles from Canada to California along the interstate, come on Tesla, unchain me, give us the CHAdeMO!!!!�

doug So a CHAdeMO adapter is confirmed for Europe as well as Japan. Seems that US would just follow.
Hmm... I thought adapters weren't allowed in Europe.�

Hooray for CHAdeMO!�
Mar 6, 2013
stopcrazypp I almost forgot about that. If a CHAdeMO adapter is legal, they could have gone with a three phase version of the Model S socket instead of a Mennekes socket as they have done now. I wonder if they were able to lobby the IEC to change the adapter ban.�

Jason S He's in Eureka, which is far enough north that Bend is about as close as Tahoe.
As a skier, I consider both places equally nice. But typically nicer powder on the more northern slopes (Oregon).�
Mar 6, 2013
Eric Bendler I would even pay $500 for it. Most CHEdeMo chargers are either 50 or 60 kw (I think). That immediatly makes the car more useful. There are dozens of these chargers in the Chicagoland area.
Waiting is so hard. It's all you think about when you should just be enjoying your car.�
Mar 6, 2013
Puyallup Bill Hate to say it, but methinks $500.00 is a bit low. I'm thinking more like $750 or better.�
Mar 7, 2013
Bipo Maybe the illegal issue is to plug a Type 2 into an adapter, but as the CHAdeMO is not under the EU norm but under its own norm (I think), maybe it's allowed to be plugged into an adaptor.�
Mar 7, 2013
drees I think you're looking at least 2-3 times $750 unless Tesla plans on losing money on them. The high power connectors and electronics are not cheap.�
Mar 7, 2013
jkirkebo The connectors probably cost a bit, but you only need a CHAdeMO inlet, not an expensive plug. The other plug Tesla makes themselves. Any electronics would be cheap low power protocol translation stuff, there is no need for any high power electronics.
My guess is around $1000.�
Mar 7, 2013
bluetinc Why do you think the CHAdeMO inlet is not an expensive plug? I priced them out a while ago and couldn't find any source of them at anywhere a reasonable cost. Do you have a cheap source?
Peter
�
Mar 7, 2013
jkirkebo Nope, but Nissan charges $700 for the QC option on the Leaf. That includes quite a lot more than the inlet, which they probably pay no more than $100 for or thereabouts.
What I must pay for one and what Tesla must pay for 5000 has little correlation.�
Mar 7, 2013
100thMonkey given what the lack of super chargers is doing to Tesla's reputation in cold weather, it would be money well spent in the PR realm to just give them away with the car upon request. $100,000,000 is a lot of lost revenue, mostly based on perception, IMHO. At least Tesla could point to the demonstration area's as an example of what the future holds. It's going to be a loong time before Tesla is able to come anywhere close with the super charger installs to the number of DCQC's we already have in the ground here in the NW, and the number increases every couple of weeks!
�
Mar 7, 2013
stopcrazypp I doubt that is the case since CHAdeMO is currently working to get their standard approved to be part of the IEC spec. If that is the case, the adapter would become illegal after CHAdeMO gets approved.
- - - Updated - - -
Well it's not just a simple inlet. Tesla also has to pay for all the R&D to basically "emulate" the CHAdeMO protocol and all the signals (including analog ones). And it'll come with extra bulky cabling to handle up to 50kW DC. Basically it will not cost any less than a UMC (which costs $1500 for the Roadster, not sure how much for the Model S).�
Mar 7, 2013
dpeilow I've said this umpteen times now but it keeps getting forgotten... IEC is a standard, not the law.�
Mar 7, 2013
drees Yep, good estimate. You can buy a CHAdeMO inlet from Nissan for about $700 retail which pretty much puts a minimum price on the adapter. Sure Tesla should be able to get it for cheaper, but as you've stated, you still need to add in the rest of the parts (it's going to need some electronics, possibly high current contactors, a decent amount of cable, etc).
Heck - Tesla charges $750 for a simple J1772-Roadster adapter. The Roadster UMC is $1500 - the CHAdeMO adapter will undoubtedly more more complex and beefier than the UMC - I'll stick with my minimum $1500-2000 for a CHAdeMO adapter and won't be surprised if ends up being around $3k.�
Mar 7, 2013
stopcrazypp I understand that, but I put it that way to simplify what I mean. I'm assuming any policy the IEC backs will be enforced via law throughout Europe.
Kind of like in the US, NEC is not a "law" but it's still locally enforced and basically illegal practically everywhere in the US to violate any part of it. The analogous part of it to the IEC adapter policy is NEC 625, which covers EVSEs. Basically no manufacturer dares to violate it even though it's not officially "law" and there may be some local areas that do not have that part of the standard in their law. It's also the reason why there are very few "mobile chargers" that can use 220V since it requires a whole bunch of safety features under NEC 625, whereas 110V doesn't.�
Mar 7, 2013
jkirkebo The S UMC costs $500. Probably because of the much larger production volume.�
Mar 7, 2013
stopcrazypp If the S UMC costs $500, my guess for the CHAdeMO adapter pricing is $500-$1200 (I'm assuming it'll be cheaper than the HPC, but that depends on how much the cabling costs), probably closer to the $1200 end than the $500 end.�

Mar 8, 2013
100thMonkey a tour would definitely be fun or maybe more like a swarm, like assign an S for each potential major route, all start at the same time from our various points of origin and post progress in real time, showing the full sprawl that is possible with the S and a fast charging network throughout the region, oh, now I'm getting excited. Tesla's already got a proving ground set up here in the Northwest and they apparently don't even know it, the CHAdeMO network is massive if you imagine a 250 mile driving radius from each DCQC in WA and OR. The west coast green highway goes all the way out to wenatchee, which is only 170 miles from Spokane, the stations go all the way out to the OR coast, the possibilities are impressive with the 85kW S combined with this network! the final locations could involve an overnight at various RV capable campgrounds, or hotels/motels with decent proximity to at least L2, allowing for a demonstration of the full distance one can go with an overnight "max range" charge for the returns. we could assure that everyone participating has a basic understanding how to achieve a desired range. doing it as a caravan could be fun but it would require a lot of logistics... there are enough DCQC's along i-5 that the S's could alternate stops to keep the flow going. the possibilities are many and right now they all hinge on a CHAdeMO adapter! Whose got connections to corporate? maybe if they knew we were planning this a few small mountains could be moved, it might just put the wind back in the sails with some impressive press coveerage!!!!
More than making each of us buy an adapter, if they are really going to be that expensive, perhaps Tesla can work out with the DOT here to provide a lock box with a chained adapter inside with adequate proximity to the parking spot and DCQC's? The good PR karma would be well worth the money, and much cheaper per location than installing as many super chargers and we wouldn't then have to lug the adapters around.

widodh Ahhh, forgot that one�
Apr 15, 2013
Vander You are right- there are already LOTS of CHAdeMO chargers about every 40 miles on many of the highways here in WA as well as OR as a part of the "green highway" and I am told in much of Europe and Asia as well. They are in public lots by burger stations, etc, and available 24/7. Being able to access them, instead of just the slow speed adapters included with my car would make trips to the airport / city, etc infinitely more convenient. In speaking with Tesla customer support last week, I was told that "there are no current plans to create a CHAdeMO adapter for the S" in spite of the enormous benefit that it would provide for people like me that have a CHAdeMO infrustructure already in place. He took my VIN # and submitted a request in to his superiors to consider it's development. He told me that the more people that placed such a request, the more influence it would have on Tesla. If you are reading this thread and think that it would be a good idea for Tesla to make a (ChAdeMO) adapter available, consider calling customer service to request that they prioritize it. Better yet, if you have any influence (?tweet-o-sphere; publishing, etc) do whatever you think might help this effort along.�

jomo25 I'd agree that they will get likely the same port. That said, it is possible that Tesla could limit the ability for the adapter to only work on Japan-spec cars via software.
But God, I hope they don't. I would see no reason not to make it available. It does nothing to detract from the value of the MS or the Tesla brand. IMO, it only enhances it. And greatly.�

Apr 20, 2013
100thMonkey ditto that... rather disappointed in Tesla with respect to this and am prepared to go third party if need be. a few of us, myself included bought the car contingent on an adapter being made and were assured that one was on the way. now, the company response is that they have no plans. We've already got more CHAdeMO up here than Tesla is planning on putting in the entire country, being locked out doesn't feel good! The reality is that there are millions of gas stations in comparison. while I don't think we need millions of fast chargers, I do think we need probably thousands at the very least, way more than Tesla's planned 100. everyone departs from varying points and goes to varying points, not just from city to city, requiring a variety of options.

Apr 20, 2013
qwk I'm curious as to where anyone would find the Tesla connector for the car end. Tesla doesn't sell it seperately, but I guess one could just buy a UMC to get it. I'm guessing that this connector is not going to be able to be produced for under $2k in any kind of small volume. How many people would buy it for $3k?�
Apr 20, 2013
jomo25 The modified LEAF EVSEs he makes start out as a LEAF stock EVSE which is modified. So, yes, the cost of the LEAF EVSE is included in the full price (or he'll modify an eixsitng one for an upgrade fee if you send him the original). But I dont know how easy it would be for the Chademo application. I dont think the UMC is rated for that much kW, so, not sure if that's feasible.
Definitely interested in one if Tesla officially decides not to release one for US owners and there are no software limits.�
Apr 20, 2013
qwk I know you couldn't use the UMC, but would need to buy one to source the Tesla connector. That connector appears to be the same. I guess he could sell the remainder of the UMC with a J1772 end to rav4 ev owners.�
Apr 20, 2013
highfalutintodd Couldn't you just cannibalize a J1772 adapter for the plug? Hell of a lot cheaper than buying a whole UMC.

mitch672 The expensive connector Phil is referring to is the Chademo female vehicle inlet connector, not the Model S side which can be fabricated with a $95 J-1772 to Tesla adapter.�
Apr 21, 2013
jomo25 Not a big deal, but I was still referring to qwk's query here: Likelihood of a CHAdeMO adapter for the Model S - Page 58, not the Chademo female inlet connector. I would imagine those are standard, whereas Tesla's is "proprietary". In any case, just hoping such an adapter is built by someone, Tesla or otherwise.�
Apr 21, 2013
mitch672 Chademo is also proprietary and a large part of the cost is the licensing fee. The Male connector with attached cord costs over $3,000 currently. The female ends are only used by Nissan on the Leaf and Mitsubishi on the iMEV, they are not a "standard" off the shelf part.�
Apr 21, 2013
qwk I just went out and looked at my J1772 adapter. I'm not so sure that adapting it to be used on a 50kw charging cable will be either easy or cheap. It looks like remanufacturing it to use in that application will cost some money.
My point is, the plugs on both ends will be quite expensive. The signal conversion box shouldn't cost too much to make, but that doesn't factor in the reverse engineering time to make it possible.
Because of the time, cost and effort involved to make one, I'm guessing that we won't see an aftermarket adapter until Tesla makes it clear that it isn't going to sell theirs in NA.�
Apr 21, 2013
drees The J1772 adapter is just a straight through adapter for each of the 5 pins, I believe - nothing special in it.
So it should be able to handle 80A - the real question: is it safe to use at up to 500VDC instead of 240VAC?
I suspect it is, so it should support around 30 kW charge rates on CHAdeMO (typical pack voltage is no higher than 400VDC, I believe). Definitely not a supercharger and only about 50% faster than twin-charging, but there are a lot more CHAdeMO chargers around than 70-80A J1772 stations...
The other alternative if you want to charge at full CHAdeMO speeds is to source the Tesla plug - one way to get the plug right now is to buy a HPC or mobile charger - sure that's $650-$1200, but it'd be nicer than using the J1772 adapter and if the rest of the CHAdeMO adapter already costs thousands, what's another thousand? :wink:�
Apr 21, 2013
Puyallup Bill If you happen to have a Zero Motorcycle, you can add CHAdeMO for $1,800. So, surely, we should be able to get an adapter for a couple hundred less.:biggrin:

Kipernicus If the requisite adapters were available, would a 60kWh Model S without Supercharger access be able to use Chademo or SAE DC?�
Apr 22, 2013
qwk I really doubt it.�
Apr 22, 2013
drees Sure, it could be done - if you could convert high voltage DC back to 240VAC, that is!�
Apr 22, 2013
gregincal Since as we all know there is only a software difference in enabling supercharging, the answer is going to be whatever Tesla chooses. It depends whether they position the supercharger fee as enabling fast charging or getting access to the free superchargers. Nobody will know until they announce the adaptors (or more likely after they announce the adaptors without saying and people ask the question repeatedly). I agree the most likely answer is no.�

Apr 27, 2013
stopcrazypp That's not an adapter, but rather an additional port (similar to the $700 option on the Leaf). On Zero motorcycles, even the level 2 charger is optional (it comes standard with level 1). The CHAdeMO option for the Zero motorcycle is only 10kW.
An actual adapter will cost more money because it has to translate between two different DC charging standards through the existing charging port on the Model S (rather than a direct connection to the battery contactors inside the car) and will have extra costs for the external power cabling.�
Apr 27, 2013
SuperCoug Interesting and insightful prediction. Makes sense actually. I really hope you're right!�
May 1, 2013
Ingineer I haven't yet had the time or a loaner Model-S to reverse engineer the Supercharger protocol, which is needed to build a CHAdeMO to S converter. If anyone in the Bay Area wants to loan me their S to take a trip to the Folsom Supercharger, that would be very helpful!
Yes, there are some awfully expensive connectors involved, though it does look like it might be possible to use one off a UMC for the S side. Tesla also will sell one in the form of a Roadster HPC adapter. Unfortunately the CHAdeMO inlet is pricey.
It's correct that there would be no need for power conversion, and most CHAdeMO stations can handle about 50kW.
-Phil�
Jun 22, 2013
saprolf A few month ago I had contact with an engineer at Tesla that is responsible for the construction of all car connectors. Due to the fact that now Tesla does not support the J1772e combo plug anymore they intended to support the CHAdeMo for the Japan roll-out.
The point is that he is now busy with the Mennekes EU IEC 62196-2 plug construction. This plug will be supported in EU as standard. Elon also said this at a meeting in Norway.
For the engineer I pointed out that we had 120 CHAdeMOs already in the US (at this time might be more today) and these Japanese stations are keep coming. I would wish to have this adapter earlier that later, because 50KW is 150% faster than my on board twin chargers. If someone gets better know please post here.�
Jun 22, 2013
Cosmacelf Well, did he say he was building a US adapter?�
Jun 22, 2013
ChadS A Tesla engineer said they intended to build one (as well as an SAE adapter) for Supercharger-capable vehicles about a year ago. I followed up with Tesla corporate to get confirmation; at the time they said Lars was not supposed to be talking about it and they couldn't comment, but they did confirm that they intended for the Model S to be "omnivorous" when it came to charging sources.
A few days later I was talking to a Tesla employee that said he had seen a CHAdeMO adapter, although it obviously wasn't ready for market and he didn't know when it would be.
Charging for hours at 30A next to a free CHAdeMO station is starting to lose its charm.�
Jun 22, 2013
Cosmacelf Stories like this and also another story I heard that the Model X development team was pulled off the Model X for about 3 months to fix Model S faults (I have no idea how accurate this story is), makes me realize just how much of a startup Tesla still is.�
Jun 22, 2013
highfalutintodd Screwups, lack of communication, priority shifts, product delays, strategy changes, and resource reallocation are hardly the sole domain of a startup. Ask just about anyone at any company ever. The seemingly better ones just do a better job of hiding it from the public.�
Jun 22, 2013
brianman It never had charm to lose.�
Jun 23, 2013
stopcrazypp Well, the Japan Model S launch is in the second half of this year so they should at least have it in prototype stage if they want to release one anytime soon.
As for the other comments, given a year has passed, it's not likely to be accurate for the current plans.�
Jun 23, 2013
ChadS My only other comment was that they said they were intending to give us an adapter. So if I am not misreading something, your take is that Tesla used to want to give us an adapter - but now even though they are building one they have likely changed their minds.
I didn't expect the adapter right away - but I very definitely do expect one. Not having one is why so few of my friends are considering the car - they see how ridiculously long my trips take, and they want to wait for the DC standards issue to "get settled" (an adapter would settle it). I love Superchargers and I am willing to wait for them to arrive on the routes they cover - but there are many trips I will never be able to take using only Superchargers, so the CHAdeMO adapter will always be a critical component to allow us owners to get around.
UPDATE: Us talking about it on these forums can never resolve this (at least, it hasn't after 600 posts in this thread :wink�
Jun 23, 2013
Cosmacelf FWIW, a Tesla employee, not in engineering, but who talks to engineering, told me recently that there are plans to make a US CHAdeMO adapter for DC fast charge. Plans can change, of course, and the info might not be reliable. But at least there's hope�
Jun 23, 2013
stopcrazypp I'm not really saying they are changing their minds, just that whatever was specifically said back then likely doesn't apply after a whole year with no movement. Plus the message was never consistent. Early on, engineers had a negative opinion about CHAdeMO, but then you also had the corporate line that the car can charge anywhere. And then throughout this thread there's some reps that say there definitely will be a US market CHAdeMO adapter, but some that say there will not be.
Definitely only Tesla can say. I'm actually not sure how effective repeat individual communication is (outside of the first contact just so Tesla has statistics on demand) esp. for a feature that never was a hard promise (CHAdeMO support was never advertised on the website nor to the press directly).
The way people got movement on 3-phase support was to have a joint letter that they made sure corporate got. And they made it abundantly clear it was a deal breaker (as in they will cancel reservations) and also cited examples why. Might be a bit late for that now as it looks like Tesla won't really be able to move the time frame any quicker than the Japanese launch. I guess the current thing is to wait for the Japanese version to come out (which seems fairly certain) and if Tesla doesn't release a US version then more energy can be focused then to get one here.�

jerry33 Of course, we also have no evidence that it won't.�
Jun 25, 2013
jkirkebo Well, 35kWh in 2,5 hours sure won't entice me to buy such an adapter...�
Jun 25, 2013
TonyWilliams That was the total connect time. For any power source, you can simply multiply the rate of delivery over time to get the total kWh delivered. There's always going to be some losses, so for easy figuring, lets say 95% efficient (delivered to car versus stored in car).
CHAdeMO is currently spec'd for 62.5kW, or about two thirds of 90kW and half of the 120kW Superchargers. It's design spec is 100kW.
You can expect to typically pull 48kW from most CHAdeMO currently deployed. To "fill up / top off" would be just under two hours. A fill up at 90kW is about an hour, and obviously quicker at 120kW.
There's no rocket science here (even if the adaptor came from a rocket science lab).
You're absolute fastest "plan C" is 80 amp AC in the USA / Canada, at under 20kW with 90% efficiency, and there are virtually ZERO of those in the wild. Yes, I'm painfully aware of the more robust three phase options in Norway and the rest of Europe, however I don't expect the charger to output anything more than 10kW each, whatever the AC power source.
Just like any charging resource in the wild, you're generally only going to sit there long enough to get home (or the next spot).�

ChadS I got an answer...and as expected, it is still officially "we can neither confirm nor deny".
However, they did also go out of their way to indicate they were very aware of customer demand, and they suspect that will grow. And that they want to address impediments to sales. So while they didn't actually say so, I feel pretty comfortable that they will offer one in the US; I just don't know when.�

DouglasR Chad, I believe you were at the Tech Talk in Seattle today. Lance was pretty definite that 1) they are working on an adapter, and 2) it will be available in the U.S., although he couldn't say when. I know that he may not be able to speak for the company officially on this, but as I say, he did sound pretty definite.�
Jun 25, 2013
ChadS Yes, he did mention it and sounded fairly positive. Though what I recall (?) is that he said he saw an adapter (which may or may not have been for the US), and that he assumed it would come to the US. Which I assume too, but Tesla corporate has not confirmed that. I say "corporate" to distinguish the people at HQ in CA that make the decisions from the long-suffering people at stores like Lance that don't seem to get any more info than we do - so you are correct that he can't represent the company position on this. Lance's story (and several others that have been posted here) helps convince me it will happen despite the lack of official confirmation; but we can't really be sure so until there is an announcement I would hate to tell people "go ahead and buy a car, an adapter will come".
Incidentally, Lance said the same thing a year ago - he had seen an adapter. I am not complaining about Lance! Or even really, with what Tesla is doing. My frustration has been with the lack of official communications, because it means I don't know what to tell potential customers (or when I can make a trip without a very long 30a stop). Though even there I have to admit - if they had said a year ago that a CHAdeMO adapter was coming but not given any more details, we would have spent the last year arguing about pricing and complaining that it is not here yet, rather than complaining we don't know if it is coming. Some things just take a long time and early announcements raise more questions.
I know they have a lot of work to do and they have been doing great so far (not perfect, but great all things considered). I trust them to do the right thing here as soon as they can.�

cwerdna Is there an official channel (where it's actually recorded somewhere) to make such demands?
I have no idea to what degree Tesla monitors these forums collects data and takes action upon it. As the former Prius Product Manager said about Priuschat at Prius Brake Recall â€" A Little More Information | Page 2 | PriusChat
Demand for a CHAdeMO adapter is obviously unrelated to satisfying regulatory requirements, but perhaps if Tesla had some actual stats on the demand or how high up (or low) the issue is in priority for customers, they might put more/less effort into it.
Just because a few folks echo their wants/needs in a forum or are the loudest in a forum doesn't make it true that many or most people want it.
If everyone who wants such an adapter actually got their request formally registered w/Tesla somewhere, perhaps they'd be more receptive?�
Jun 25, 2013
ChadS I would recommend that people that would like to see an adapter send email to [email�protected] and ask when one will be available. They won't give a direct answer, but they do seem to keep track of such requests.
I could be wrong, but my feeling is that we don't have to do more than that. Well, that and be patient.�
Jun 25, 2013
cwerdna ^^^
If that's the channel, it might be good to also state why (e.g. there are x CHAdeMO stations in ____ I could possibly use, there are x CHAdeMO stations in the US, there are no Superchargers near me, etc.)
People who are pushing for Frankenplug adapters won't be able to make such justifications... :tongue:�

stopcrazypp I think what he means is the slow average power (14kW given 35kWh in 2.5 hours) and if it's a Model S it doesn't make sense for it to be that slow since even at the end of the tapering, the Model S goes down to 80A (~30kW).
It seems more likely this is a prototype of some other EV unless the times you are talking about have the car connected without being charged (as in charge cycle finished before 8:30pm).�

widodh For people who are interested in how this all worked out: Endorse my letter to Tesla for supporting 3-phase charging for the Model S
So if you really want CHAdeMO support, we should set up such a joint letter again. I'm not going to do it this time, but I'll happily sign a document since there are dozens of CHAdeMO chargers around here.�
Jun 26, 2013
ChadS That was very nicely done work, widodh, and could be an excellent model if needed. My guess is that it is not needed in this case, but I could be wrong. Even though I'm pretty sure they will make one eventually, such a letter might raise its priority and get it here sooner.
Ironically, it is possible (this is pure speculation) that part of the reason the CHAdeMO adapter was delayed is that the charging engineers all switched to three-phase support when you bumped its priority. Not complaining even if that is true - 3-phase support is important! - just making an observation.�

EVNow Considering the low number of supercharger location in the NW, I wonder if that is because Tesla expects to sell the CHAdeMO adapter - and think that will take care of the QC needs.�
Jun 26, 2013
100thMonkey if so, it seems that that approach is backfiring... there is mounting frustration at the combined lack of planned SC's and lack of a CHAdeMO adapter.
