CHAdeMO Adapter part 1

    I don't think you are interpreting this correctly. "Adapter + Onboard Hardware Activation" means that they activate CHAdeMO charging only, not supercharging. Or, at least, that's my interpretation.

    Hmm, you may be right though it is somewhat ambiguous. I assume that it uses the same DC charging HW.
    �

    markb1
    I'm sure it is the same onboard hardware. But when you pay for supercharger activation, you're really subsidizing the installation and operation of the superchargers. Makes sense that if you only what to use CHAdeMO chargers, which don't cost Tesla anything, you should get a discount.

    I disproved this many months ago, and confirmed the wording with Tesla. The "Activation" is to enable Supercharging capabilities on the car. The ADAPTER will WORK with ALL supercharging enabled cars.

    Link? I agree with your last sentence, but I think the bundled price is for CHAdeMO activation only.

    Cant link to a phone call with the Tesla Charging team :) CHAdeMO will not be activated without Supercharger Activation. They are one and the same.

    I like the idea of having another fast charging option so I decided to call some of these Nissan dealerships to see how agreeable they would be to me using their Chademo chargers. We have 2 dealerships within a 50 mile radius of our home in southern NH and both basically told me politely No Way! The other disadvantage is that they're only available during business hours. So I think this would be a waste of money. So far I've seen just a couple of Chademos that weren't owned by Nissan dealers.

    Then their pricing doesn't make any sense. I think it's more likely that the Tesla employee didn't know what they were talking about. Or maybe they have changed there plans and haven't update the web site, yet.

    My understanding is exactly as islandbayy describes. Enabling Sc and Chademo are one in the same.

    There are areas wher there are plenty of public, non-dealership Chademo stations. Mostly in the Pacific Northwest, California, and Phoenix markets.

    well then, my original point seems to hold - very poor pricing on the adapter.
    �
  • Mar 14, 2014

    I'm puzzled about why this is poor pricing. If you buy an expensive piece of hardware, they give you a break on the software needed to use it.

    If you already own the software, I suppose you are worse off than if you'd waited to buy both together. But, then again, you've been using the software for some period of time for other things.

    I mean, I like free stuff too, and I'd be happy to pay less for the CHAdeMO adapter. But the pricing seems perfectly rational to me.

    Phil -
    I came to a similar conclusion after reading that description, and I sent an email to ownership to complain.

    They clarified that for cars that don't have supercharging enabled, that the $2400 before delivery or $2900 after delivery is in addition to enabling Supercharging... The verbiage on that page is not clear, but apparently there will be 3 tiers:
    - No DC charging enabled (60s only)
    - CHAdeMO only
    - Supercharging and Chademo (if you buy the adapter)...

    Very confusing if that is the case...
    �
  • Mar 14, 2014
    markb1
    This reinforces my belief that the people at Tesla answering these questions don't know what they're talking about. (It wouldn't be the first time that Tesla has demonstrated that have huge internal and external communication problems.) The part about $2400 or $2900 being in addition to supercharging doesn't make sense. The web site is at least clear that the adapter is $1000 if you already have supercharging enabled.
    �
  • Mar 14, 2014
    ZBB
    I agree... simplest would be:

    Supercharging $2k
    CHAdeMO Adapter $1k

    Oh, you didn't buy Supercharging before you ordered your car? That's $500 more...
    �
  • Mar 14, 2014
    Gizmotoy
    No kidding. If you already have your car you pay $2500 to enable Supercharging, $1000 for the adaptor, and then a $1900 "you didn't enable Supercharging before buying the adaptor" fee? That's pretty obviously incorrect. Someone at Tesla was just confused.

    If all the reps being asked also reference to the same page or an internal document that is worded the same way, I can see how even the reps can get confused. That page really needs to be updated and simplified ASAP, but I guess this is a low priority given the adapter isn't even out yet.

    Maybe fw6 will introduce a new CHAdeMO activation feature. I'm guessing the adapter has been delayed for fw6 anyway.

    IMO, Tesla shouldn't be charging to enable SC in markets where there are no (or very few) SCs. For example, we may have 3 or 4 SCs in the UK at some point before 2015, but there are hundreds of CHAdeMO charge points. The SC activation fee for S60 owners is the equivalent of 11,250 miles in a high-performance diesel car. Buying a CHAdeMO adapter puts that number up to 16,250 miles - and CHAdeMO charging is not always free.

    It would have been ideal if they could have bundled the adapter with the car in the UK, as they will in Japan, at least until the SC network is up and running here.

    It would be clearer if they called it a DC charging activation fee, as it's tied to all DC charging, not just Supercharging.

    On the Norwegian EV forum a member posted a close encounter to the mythical chademo adapter in Sweden yesterday. A Tesla employee tested the chademo adapter on charging stations between Stockholm and Stavanger. No pics, unfortunately.

    Interesting, because this means working prototypes has been produced and is actively being tested, and that the EU version is probably as far along as the US version.

    I did some Googling, and there is a "Charles Thieret" who works/worked for a car dealership in Ballwin MO (near St Louis), but not a Nissan dealership. There is a Nissan dealership a mile down the road, with perhaps the same ownership or perhaps where he now works, but the pictures of the Chademo there (on Plugshare) do not match the picture here posted. So, I dunno, but I thought I'd at least provide what I found, so you all don't waste the same amount of time :)

    Does anyone know if all Nissan dealers are required to install the high power (CHAdeMO) charging stations at the dealerships? If so, it could dramatically increase the number of L3 charging options around the country (provided that they allow MS owners to charge there).

    I'm going to guess that since we know that Supercharger access is a bit more than pure SAE communication, I would bet that they use the same form factor for any of the DC charger adapters (G /T in China, CCS Combo1 in US, CCS Combo2 in Europe, and or course CHAdeMO worldwide.

    Man I wish this was available already. I've been on the waiting list since it was first posted in the store.

    I'm going to Joshua Tree National park this weekend and since the Indigo Super Charger is not ready, the CHAdeMO at the Desert Hills Outlet Mall would make the trip significantly easier. I might end up at the Palms Springs Service Center, but that is quite a bit out of my way and slower than the CHAdeMO.
    �
  • Jun 5, 2014
    gregincal
    Supercharger access may be more than pure SAE, but SAE should be a subset of supercharger, so CCS<->Model S could still be complete passthrough. I also hope that the form factor is smaller for SAE. We shall see.

    European design studios for MS now have the possibility to order the chademo adapter together with the car. 950 EUR.
    This probably means a european version should be available in the october time frame at least since delivery times for new orders are still 4 months for P85 prioritized delivery.

    It was available to order with the car already in February-March, but was later removed again. In March or so it was still possible to select it when you had ordered and went to change your config, there the option for CHAdeMO adapter existed. And I've seen Tesla offers for used cars that had CHAdeMO adapter listed in the options and the car could have been delivered within a week (though I'm guessing the CHAdeMO adapter would have been delivered when available).

    Thanks. We ended up going to Jumbo Rock Campground, which more on the north side.

    The service center worked great. My son and I walked down the street, ate a nice dinner and watched a movie. When we got back we had a full charge. That was enough to drive to Jumbo Rock, then all the way home on Sunday with no further charging needed.

    Next time will be even easier, when the Indio Super Charger is active.

    Sorry I'm a bit late to the party re: the CHAdeMO adapter, guys. Wasn't following the news (or lack thereof) because I didn't know of a single CHAdeMO station.

    However, recently a key SCH level-2 charger on my cross-Canada trip I have planned later this summer was replaced by a CHAdeMO station. It was the only high-powered L2 in the region, so I really needed it. Looks like I'll have to pony up the cash for the adapter, if it's even available by August. :mad:

    Even though I'm on the wait list, I'm thinking I won't buy one now.

    It would be nice to have for our road trip this summer -- would give optionality when in CA, OR, WA and BC. But after the trip, I don't think we'd really use it much -- perhaps once a year in SoCal... But the Supercharger buildout otherwise covers most of our needs...

    Tesla is increasingly moving towards not making any promises on timelines. Which is a good thing considering that they tend to be overly optimistic.

    Elon probably sets aggressive goals in the (probably somewhat correct) assumption that setting high expectations means things happen sooner. But debugging complex systems is something you really can't do on a fixed schedule. It takes what it takes.

    I once was asked by a former boss, "How long will it take to finish debugging?" I told him, "Between two and five months. Two if we don't hit anything unusual; five if we're very unlucky." He was unimpressed and decided it would take two months. It took five. Would have been six except for a lot of overtime.

    I must repectfully disagree. I have 40 years experience as an electrical and software engineer. This is not a complex system, granted not simple but not unusually complex. It is a connection between two well defined interfaces. I don't see the potential for difficult debug problems.
    At the very least they should take down the coming soon message to set more realistic expectations if delivery is that uncertain.
    �
  • Jun 16, 2014
    Cosmacelf
    The two interfaces are anything but well defined. Both are proprietary, both are evolving, and Chademo has several different manufacturers implementing it. That always leads to different interpretations on how to handle corner cases and ill specified elements. And it isn't only software they are testing, It is also electrical hardware and mechanical hardware.

    Sorry, I only have 30 years experience as an electrical and software engineer so I clearly have no clue.

    Look at how chademo actually works and I think you'll change your opinion on that. It's not a good "standard" IMHO.

    Even the simple-minded J1772 standard is problematic in the real world because it doesn't adequately constrain the implementation in terms of timing, etc., so getting a station to work with all vehicles, and vice-versa, can be a challenge.

    Yes, there were a bunch of L2 Eaton stations last year that would work with 2011-2012 LEAFs, but not with 2013s. Eventually, Eaton issued a firmware upgrade to correct the problem, but did not own up to an error. Instead, they stated that both the '13 LEAF and the charging stations respected J1772 standards, but that there was enough gray area in the standard for incompatibility to arise.


    However, for that you might have to move you own post to snippiness, though.

    Regardless of the complexity, this is not just an engineering problem. It may well be "easy" to engineer a prototype solution that works well in the lab. Then it has to be tested in the real world and problems inevitably arise. Once the rounds of testing and tweaking are done, there is certification (international products have lots). Throw in a cycle or two for mechanical engineering. Then product engineering (for manufacturability and such). Then production. Each step can have hiccups which delay the product. It's not hard to take 6 months to ship after completion of a working prototype. Mature organizations build in a lot of lead time for the back half, I think Telsa isn't quite there on that part.

    Well in Estonia there are now at least two cars who ordered the car with the CHAdeMO adapter and actually paid for it in their final bill, but didn't receive the adapter with the car when they were delivered in the past two weeks. They're not happy campers as they chose single chargers because of the adapters and one of them is in fact a cab company who has now serious limitations on the cars usability due to lack of CHAdeMO adapter that they have paid for.

    We know Tesla is working on one from their own website. The adapter will be useful to some and not very useful to others. Those that want it should get and and those that don't shouldn't. Pretty simple.

    Nissan, near me, put a clever CHAdeMO fee rate on their unit. $3 1st hour, $10 per hour, thereafter. Publicly accessible, 24/7. Too bad there's no adapter, as many of these units are ready and waiting.

    Yes, news of a single CHAdeMO only NYC station, with public involvement through the Nissan Advantage program, is another wrench in the CCS entrepreneur's plans. The opposite would also be true, not to pick favorites. Only because it seems viable, my hope is BMW blows off CCS, knowing the partnership is so non-committal, and licenses the Tesla SCs. Either way, I hope this gets decided more than I care who wins.

    Is that the same Tesla engineers who were "certain" that the adapter would be released in December, I mean, March, I mean, June, I mean, August? They have not the slightest clue what they are doing or when they'll be ready. And they have told us for about nine months that it will be ready in "1-3 months" - with the target conveniently shifting into the future.

    I will receive my Tesla in September and had hoped that it would come with the Chademo adapter. I have just been in contact with the Delivery Experience Expert and asked him about delivery of the adapter. He responded that it will be available at the end of the year. So again further delays. That's a real problem because Fastned it installing 200 Chademo chargers along all highways in the Netherlands. But I cannot use them

    Saw the adaptor in use charging a white tesla in Los Altos (evgo chademo station in Wholefoods) yesterday. Kinda clunky but I suspect the size/heft of it helps keep that nasty big metal chademo connector away from the paintwork :)

    Interestingly, the station was showing a percentage battery level of the tesla on the station screen. No idea it was accurate, but didn't know it could do that. It showed charging at 378V, 107A (~40kW).

    Learned that Japan delivery of Model S is delayed again until September. I heard that CHAdeMO testing is going well and Tesla will bundle CHAdeMO adapters to all Japanese cars. So I believe the product is almost ready to release!

    I suspect whatever production they have of these will go to Japan and Europe deliveries, with USA "after sales" being further delayed.

    Japan has very little number of cars and Europe being different physical adapter, I personally guess they build enough numbers for Japanese and American orders. At least technically make sense.

    So I spoke with somebody from ABB this morning regarding a Quick Charger and finally we ended up talking about the CHAdeMO adapter.

    What he told me is that Tesla has been in contact with ABB to test their adapter on their charging stations. He mentioned that the adapter would be released in September/October.

    Another he told me that some CHAdeMO chargers overheated due to the long period of a 46kW draw by a Model S. A Leaf draws 50kW for 3 minutes after which it starts to taper down towards 40kW, 30kW, etc. Since the Model S has such a big battery it can draw 46kW for a longer period causing some chargers to overheat.

    Thats interesting... CHAdeMO reliability has remained very poor in the UK (24 out of 122 chargers offline today) and I wonder if the recent warm weather and increased usage is indicative of a heat related problem :confused:

    Japan is definitely warmer than U.K. and I'm not sure why they are so unreliable. Are they of some specific manufacturer's? We have highway network covered by many CHAdeMO chargers, which are regularly frequented daily by Leafs and Outlanders. Some chargers are used more than 400 times in a month, 28 times a day at peak.

    But still, when used, they rarely ever are at >45kW for 30 or more minutes without a break. An empty 85 will draw >45kW for more than an hour before it starts tapering below that

    I agree that MS will give more stress to CHAdeMO chargers but in the U.K. case mentioned above, this doesn't apply as the adapter for MS hasn't been available yet.

    A heat-related problem that the heat has Leaf owners going on long trips. :p

    The problems in the UK are typically related to the DBT-CEV chargers that Nissan commissioned and has deployed in large numbers. They have proven unreliable and I don't think it's reasonable to tar all CHAdeMO chargers with the same brush.

    While it is true we don't have the Model S adaptor in Europe yet I was interested in the over heating comment because we do have some locations with queues of Leaf's which might induce an overheating problem.

    Do you know whether evstatus can list failures by charger type? I've been trying to correlate the failures with charger brand to confirm what you say but haven't succeeded.

    I know that the Nissan CHAdeMO stations (most often found currently at Nissan dealerships and eVgo installs in the last 9 months) often have overheating problems. The problem is that the cooling system needs frequent maintenance. When the weather heats up suddenly, you will find them going offline like flies.

    Instead of going offline completely when overheated, they should simply go into reduced power mode when temperatures get too high (like the Model S does when pushed hard) and generate a warning so that a maintenance crew can be deployed.

    Other stations that have been known to be unreliable are Blink CHAdeMO stations.

    This stuff shouldn't be rocket science - would be nice to know which stations are the most reliable.

    A few here have said CHAdeMO is the superior standard and we should deploy more of them. Starting to think at least the initial head start they have might have been rushed with inferior hardware.

    Apparently, rain can fall right into the vents of this model, so that doesn't help. Also, the dealers and others that Nissan distributes these to aren't necessarily very diligent and knowledgeable enough to carry out the required routine maintenance.

    That ABB CHAdeMO chargers don't work with one hour continuous use is pretty sad. Once again goes to show only Tesla is really serious about EV. Most everyone else aren't taking it seriously.

    Yep. Frankenplug and CHAdeMO are pretty much the "compliance chargers" of the charging world.

    I never said that, ABB told me the opposite. Other chargers failed. ABB seems very serious about building a reliable charger.

    Exactly - in fact the architecture they use is pretty similar to the superchargers and predates them.

    ABB have been achieving 100% uptime in the Netherlands when others were getting ripped out for unreliability.

    I can give them a pass on the testing failure as they didn't originally have vehicles to test with.

    But on the design side overheating protection (with current ramp down or whatever) should have been there from the beginning IMO.

    I think you got confused. It's the cheap Nissan chargers that are failing, not ABB chargers. The statement was by an ABB personnel, but he wasn't talking about ABB chargers, but ones from other companies.

    It seems fairly unbelievable that Nissan was able to build a $15k quick charger, but it's unfortunate they had to cut corners to build one.

    Sorry, my bad. I guess we know now why the Nissan chargers were so cheap then.

    There are more makers of CHAdeMO stations than just ABB, Blink and Nissan. There are DCFC units that have been replaced with Nissan units and the reliability has been greatly improved. Example: Stanford Shopping Center. That location has covered parking, so that may be a factor.

    Fyi, a ABB CHAdeMO charger is roughly EUR 35k

    But we at least have more conformation that they are working on the adapter.
