Tesla Motors
has confirmed that the all-electric Model S luxury sedan will have a CHAdeMO quick-charging adaptor when the model goes on sale in Japan. The news was first reported in Japan, where CHAdeMo is the winning fast-charging option. The adaptor will make it possible for Tesla owners to recharge at almost 1,900 quick-charging stations across the country, Green Car Reports notes, where CHAdeMO is the DC-fast charge standard for models like the Japanese-made Nissan Leaf and Mitsubishi i.

More than 20 Tesla stores in Japan will start selling the model later this year, though no pricing has been announced. Tesla hasn't said whether CHAdeMO adaptors will be available for US versions of the Model S, which in November won Motor Trend's 2012 Car of the Year award.

The CHAdeMO quick-charging standard was established in 2010 and is supported by Nissan and Mitsubishi as well as Toyota. US and European automakers such as BMW, General Motors and Volkswagen are supporting the newer SAE Combo standard because of its ability to have a single charging port for both standard and fast-charging stations. Tesla doesn't like either of these protocols, and developed its own Supercharger technology, which is why an adaptor is necessary in the first place. No similar adaptor for the SAE Combo connector has been announced.

      "That seems to me to be a big deal. How many SAE Combo chargers are installed right now? How many Tesla Supercharger stations?" How many ICE are driving around right now versus EV's? You see, that kind of comparison doesn't always add up. Although it is of course positive news that the Model S will be able to use the existing infrastructure, Chademo is on it's way out. The Japanese manufactures are going to adapt the SAE Combo plug by 2020. Now if Tesla would confirm support for the Combo plug, that would really be big news.

      It is like the Apple Iphone 5. No use of a mini usb, but a special "lightning" port... This option will never come to the US

        The Tesla ChadeMO adapter will be on the bottom. "Phew!"

      This is kind of a big deal if they offer those adapters in Wisconsin. Here in Madison we would need a quick recharge if we were to go to either Chicago or Minneapolis (and make it back). The only fast chargers available in either city are Chademo, and we won't see super chargers for a few more years. Good news indeed, just make sure they're available to everyone Tesla!

        Grendel, I agree. What I was saying was that if you own a Tesla in Wisconsin, the Chademo charging stations will allow you to drive to Chicago and maybe Minneapolis in the absence of Tesla's super chargers, so getting the adapters is important here.

          That makes sense. Thanks for clarifying.

        Tesla's Superchargers are proprietary and will only work for Tesla Model S's and any future car they build. Those are the only chargers that Tesla is building.

      Geez, but ABG is hurting for news. First they post a repeat of a stupid article they posted two weeks ago. Now, the big news is that the Model S will have...an adapter!! :) (shaking head)

        What? The availability of a CHAdeMO adapter for the Model S would actually be very big news. There are significant technical issues which have to be overcome to provide an adapter for CHAdeMO. There are reportedly 1381 CHAdeMO stations in Japan right now, and another 517 outside Japan. http://www.chademo.com/ That seems to me to be a big deal. How many SAE Combo chargers are installed right now? How many Tesla Supercharger stations? ABG posts lots of things that aren't newsworthy, but I am perplexed as to why you think this is not newsworthy. The criticism I have is the wording "Tesla Motors has confirmed ...". If so, then why isn't there a public press release or any mention of this at all on their web site? If there's no corporate communication on the topic, then who exactly has confirmed it?

        Please allow me to reply with the opposite perspective. This is the first official confirmation that I am aware of of cross-standard quick charging. Tesla's charging connector, both smaller and much higher powered than the competing two standards is quickly proving the charging standard wars to be a non-issue (at least for Tesla owners). Even if Tesla never licenses its technology to another automobile manufacturer, the fact that Tesla's can charge at Supercharger stations, any SAE J1772 L2 charge station and now CHADeMO QC stations, unifies the charging network (at least for Tesla owners) in a way that only ICE drivers enjoy at the moment. That becomes more important as Tesla move more mainstream with Bluestar vehicles, or if Tesla licenses its charging tech, all the sooner. I think this is very important news to the EV ecosystem--thank you for posting, Danny. -Brad

        Guess they couldn't find any Audi/VW quotes about how they're totally committed to electrification to print. NAIAS next week hopefully will speed up the news rate.

      Nice. I wonder how much it costs though. Well, whatever. If they can afford the car they can afford the charger dongle.

      There are 158+ Chademo fast chargers in the US currently with a BIG push of installing going to happen this year. We have driven several 300+ mile trips in our Leaf using the fantastic Chademo infrastructure built out in Washington and Oregon. The Chademo stations that are already installed are just that many less Superchargers that need to be installed for US wide coverage. I have been told by Tesla reservation holder customer service that they had been planning a Chademo adapter for a while, good to see some kind of official announcement. I am sure the adapter will be available in the US as it doesn't matter Chademo in Japan, Chademo in the US are both functionally identical. In addition I would love to see twin J1772 adapter/inlets that could put 1 J1772 to each onboard 10KW charger allowing for 60A 240V charging at any public station regardless of phasing.

        Where? Where did you see an official announcement? The only thing in the story is a claim that "Tesla Motors has confirmed" it, a claim made without any proof whatsoever. If Tesla Motors has confirmed it, then shouldn't there be a press release or something SOMEWHERE from Tesla that confirms it? If not, then who at Tesla made the claim, and to whom? It may in fact be true, but right now this is a rumour at best.

        I doubt there is a big push of installation to happen this year. The same thing has been said for years. There's no reason to think it'll happen this year any more than hit has any other.

      I posted something similar at GCR, but I'll repeat most here since the laziness of these blogs is really getting to me. "More than 20 Tesla stores in Japan will start selling the model later this year..." Do you have a source for that? (I realize you're just copying from GCR without bothering to confirm.) Did you bother to call someone at Tesla? Does that even begin to make sense that Tesla would need that many stores in a country that small? Don't rely on Google translate for Japanese. As far as I know there is one store and one service center in Japan. http://www.teslamotors.com/findus/stores From my reading of the MONOist post (I've studied Japanese for some years), they mention that Tesla already has more than 20 Roadster charging stations (HPCs) installed in Japan. (Not 20 Tesla stores!) Here's a Google map of Roadster HPCs in Japan: https://maps.google.com/maps/ms?ie=UTF8&oe=UTF8&msa=0&msid=205212913252844408678.00049db3a7393559861a0 While the Model S supporting CHAdeMO (at least through an adapter) in Japan is a no-brainer, how about you guys do some journalism and try to find a primary source instead of copy and pasting from a blog that misquoted another blog that's in a language you can't read. I'm sure there are people at Tesla you can call or email.

        "how about you guys do some journalism and try to find a primary source instead of copy and pasting from a blog that misquoted another blog that's in a language you can't read" Exactly! As I said below, if "Tesla Motors has confirmed" it, then why isn't there a public press release or any mention of this at all on their web site? If there's no corporate communication on the topic, then who exactly has confirmed it? Probably no one. This site just makes stuff up. "I saw it on another web forum" is not the same as "Tesla Motors has confirmed"!

        Btw, GCR originally got this story from TMC here: http://www.teslamotorsclub.com/showthread.php/7107-Likelihood-of-a-CHAdeMO-adapter-for-the-Model-S?p=249931&viewfull=1#post249931

      Is it going to be an option or standard equipment? I could see these being given as standard to 40kWh ModelS. Maybe. But I'd like to have the option no matter what battery I buy. And what is the approximate range/hour for each of the two quick-charging? Does anyone know? I'd be a bit mad if Tesla refused to sell it if an owner wants one. I'd need to check to see how many of these there are in Seattle first but in any case it's frustrating when different options are kept from the US market. If Tesla did that I'd be surprised. Maybe roll them out in Japan first but eventually produce enough for all markets to have the option.

      Sorry. Tesla has a bunch of adapters for the car. I didn't know CHAdeMO was any bigger than any of the others. Thanks for the clarification.
