Potential buyers of the upcoming Tesla Model S shouldn't expect to find a J1772 connector under the charging flap. The SAE International standard may be on board most electric vehicles, including the Nissan Leaf and the Chevy Volt, but Tesla has never liked the design.

Calling the standard connector "ugly," Tesla has instead developed its own plug and charger that will be available to Model S owners. Compared to the home setup for current Tesla owners, the new solution is more compact and much neater.

However, Tesla's dismissal of the J1772's aesthetics shouldn't be taken as a sign that Model S owners will be left with few alternatives when it comes to juicing up their new sedans. Tesla says the charging kit each owner receives will include connectors for standard 120v and 240v outlets, as well as an adapter for the plug-ugly J1772.

Using its custom connection, Tesla predicts that the Model S will recharge at a rate equivalent to 62 miles of travel per hour of charge when connected to a 240v outlet with high amperage – considerably faster than most home chargers.

      A very relevant precedent can drawn with mobile phones! Each company, (and even model) has it's own propriety charger. The chargers always outlive the phone. Very wasteful and inconvenient.

        But the Tesla is the equivalent of having a mobile phone that charges BOTH with Micro-USB, AND Tesla's own proprietary charger. Nothing wasteful of inconvenient about having two charging options. First via Tesla's own higher power charger when you want it, AND also be compliant with the open standard. There is absolutely no comparison between what Tesla has done, and mobile phones that were completely 100% locked into being charged just by their own proprietary charger. It is a fallacy to make such a comparison.

          PR, If you had read my much earlier post, I refer to the use of adaptors. However, the fear is that the more complicated charging, battery regimes etc, seem to those who are not so familiar with the intricacies of EV's, the difficult it becomes for the general public to accept adoption. The fact that the communications industry has adopted a standard, is evidence that a similar industry has recognised, and resolved the problem.

        What's Elon's ego have to do with it? It's not like he rejected J1772 and is demanding his own standard. Elon took his own charger that was developed and sold BEFORE J1772, and he ADDED the functionality of it being 100% compatible with J1772 along with Tesla's legacy system. I'm not sure where you get that being an ego trip, because he bowed to J1772 and made his own legacy system 100% compatible. That would be like saying the makers of Betamax would have been egotistical if they had made their players also be compatible with VHS.

        as much as I dislike the existing charge connectors, I agree Tesla doesn't gain much by not supporting j1772 or the equivalent for EU cars. they could then add their own small fast DC plug at a 45 degree angle above the j1772 so the port doesn't have to be bigger than otherwise. and if compatible with chademo then have an adaptor for that. Tesla's probably not in a position to dictate standards for the world, even though theirs is better.. it's a shame that we don't already have an intelligently designed global standard. we might see more changes

          nothing wrong with the sentence, it's just more complex than you'd like. I also expected the adapter but I meant direct support. having to use an adapter is not terribly elegant and unless it's locked in, it's something punks can steal while it's charging. when other EVs visit a tesla house they can't just plug their j1772 in as easily either. if at all. I think what I suggested is more elegant.

        The J1772 would work if they wanted it to work. It's spec is to handle AC Level 2 240 V Split phase 80 A = 19 kW so would recharge the large Tesla S pack in under 6h from completely dead. (half that for the small pack). Obviously most users will be able to charge quicker as they won't be discharging that low. Mind, Tesla are happy to charge $750 for the adapter...

          The J1772 standard should be fine to use, Tesla used to say that "we" should install 70amps(?) even for home charging. Which the J1772 is fully capable of. So I guessing they just dont like how it fits their car.?.? Jake... We may not know for certain what the J1772 adapter price will be. But we do know what they charged for the J1772 adapter for the roadster...

          @Naturenut99 I'm saying it might be included with the car (so the price is $0). The website says: "Model S comes standard with everything you need to plug into the most common 240-volt outlet, standard 120-volt wall outlets and public stations". The "public stations" part implies J1772; it also appears you get the standard NEMA 5 120V connector and the NEMA 14 240v ("most common 240-volt outlet"). http://www.teslamotors.com/models/features#/performance The Roadster is kind of different in that the adapter was created after the Roadster has been on the market already, so Tesla's mainly selling it as an aftermarket addition.

          "Mind, Tesla are happy to charge $750 for the adapter..." At this point no one knows if Tesla will charge extra for the adapter. The main thing the J1772 won't work for is the DC charging that Tesla wants. J1772 DC probably won't be out in time for Tesla to put it in the Model S and one of the initial goals was 45 minute charging (which requires DC). 3 phase charging is another issue, although Tesla doesn't seem to have any plans to support it at this point.

      Level 2 top up charges are no less useful for Model S owners than anyone else. They all charge at the same rate. A 6kW charger will put about 20 miles into a Tesla Model S in an hour, just like any other EV (some get less actually).

      Why is everyone angry that Tesla is 100% compatible with J1772 connections via an adapter? You would think that everyone would be HAPPY with Tesla being 100% compatible with J1772, considering that Tesla has been SELLING EV's long before J1772 was ever even proposed as a standard in the form it is now. I guess that is what happens when the title of the story is what it is, instead of "Tesla will be 100% compatible with J1772 standard".

        100% compatible with J1772 connections via an adapter It seems that most of the people complaining on this tread didn't read this fact! I am sure that Tesla will include this adapter for Model S to J1772 and place it in the boot so you can charge up wherever you want. People are going to level nasty condemnation at Tesla left and right because they forget that Tesla is a very new car company that only produces high performance electric sports cars as of yet; and have only release one car model so far; the Tesla Roadster. The model S is their second car. It would do these people a lot of good to go read wikipedia about GM's second car, Ford's second car, Mercedes Second Car, ect. Wake up. The emerging field of mass market lithium ion electric vehicles is still very new. You can bash Tesla all you want for not putting a J1772 plug on their model S, but that says almost nothing as the vehicle is 100% backward compatible with an adapter they will include with the car!

          @Ele Truk Uh, I'm pretty sure they did. Heck, I'm pretty sure the current 80 amp max output (as opposed to 30-40 amps in the previous spec) was from their input as a member of the committee (since the Roadster's onboard charger already operated at 70amps when they were drafting it; none of the other members had/have any plans to add an onboard charger exceeding 30 amps). But it seems the committee picked the Yazaki connector (and Tesla might not have had a competing design ready at the time). The current decision not to have a J1772 socket probably has more to do with the DC situation, than level 2. If it wasn't for DC, I would completely agree there is no reason for a proprietary port.

          I think the existence of an adapter (esp. if it's included with the car, which initial indications seems to say it is) is more than just a strawman. Also if it's only 1/2 soda can sized like reps say, it's really not that big a deal in terms of inconvenience. With the adapter plugged in, there's really no difference with the other cars in the market. I highly doubt any business/government will seriously consider installing a public Tesla level 2 (works only for Tesla) over to a J1772 level 2 (which will work for all plug-ins). They've already removed most of the public EVSEs for the Roadster to install J1772s. On the other hand, they may choose a Tesla DC (only for Tesla at this point) over a CHAdeMO (only for Nissan and possibly Mitsubishi). I think Tesla's decision mainly has to do with DC (which the article doesn't mention at all), not simply aesthetics (I would agree with you if that was the case).

          I think you are the one sowing market confusion. The Tesla charger will be inside the Tesla owner's garage. Why such a big stink about other people's cars not being able to fast charge inside the Tesla owner's garage? If the Tesla owner gets another EV, they will want a charger for each car anyways, that way they can both charge at the same time. So this isn't even going to be some massive problem for a 2 EV family. If they really, really, really are so put out by having 2 different chargers, they can just get 2 J1772 chargers, and use the adapter on the Tesla. Finally, if it turns out to be such a big deal (which it won't, it's just a figment in the imagination of folks who have already been on the record hating Tesla and claiming stuff like they will go bankrupt) the easy solution is just another adapter. "why is everyone angry that Tesla is 100% compatible with J1772 connections via an adapter" is NOT a strawman. It is a statement of fact. The Tesla DOES use an adapter to be 100% compatible with J1772, and select people here are certainly bent completely into a pretzel that Tesla uses an adapter to be J1772 compliant. Unless you are saying that the problem people have here is that they just are blinding themselves to the fact that Tesla IS 100% compatible, by ignoring the existence of the adapter. I just can't see your point.

          Market confusion? The market is just emerging. Tesla is making it now. It's part of innovating. They set a sub-standard J1772 at 30-40 amps until Tesla pushed them to make it higher. They're not waiting for everybody else. That's like saying we should all forget diesel because we all use gas. No, wait we should all forget premium gas since the majority of cars use regular unleaded. If you read the specs on the Tesla connector, it is SUPERIOR in technology and in utility(smaller better design and two in one). It's just a transitional phase for people to get used to for the innovation that they are doing. Does anybody remember when the first ipod came out it used a firewire to transfer data? Then they switched to a 30 pin wire. I would say the current j plug and tesla plug is similar to that. When there are enough of the tesla plugs it won't be such a big deal. After all I'm not going to be charging my apple products with non-apple chords. I had to buy an adapter to plug the apple products into a standard 110v outlet. What's the difference between that and a tesla plug having an adapter? How is that any different now for the Leaf and Volt having to carry an adapter for the 110v outlet? It's also branding themselves on every level to have a nicely designed product without stopping you from charging on a j1772 system. In the end, the market will decide. I just don't see how the Tesla's charger will be beaten by the J1772. After all, all EVs will most likely carry some kind of adapter for the 110v outlet for universal usage everywhere. Adapters is part of the electronics world. EVs are no exception to it.

      The 30pin was what the iDislikes were talking about. But its ok for Apple to stick with their 30pin IO/ power connector standards. Tens of millions of iPod's, iPhones, iPad's, Car Stereo's, Home Stereos and other accessories for iDevices use the 30pin dock standard/ cable connector standard. They came out with something that works and kept using it, allowing for in platform backward compatibility. It would not be eco-friendly to switch away for apple, since moving to a new standard would render all of the previous accessories and docks incompatible.

      Somehow a lot of people seem to think the primary objection to the J1772 level 3 design is appearance. The objection is that it is much bigger than necessary (a compromise to keep all committee members happy). See it here: http://www.sae.org/mags/aei/10128 With more pins and larger size it is harder to plug/unplug, and costs more. This J1772 has 2 small pins for communications (like the Tesla), 3 larger pins for 120/240Vac and ground, and 2 even larger pins for DC. Tesla has only 4 pins, 2 small and 2 large. I too think there should be an accepted standard, but am not happy with any proposed, as I think the standard should allow for 3ph AC as well as DC bringing the pin count up to 5.

        Tesla is AC only, they don't have a DC fast charge option. Sure they can charge at 90Amps when available (which is pretty much at the dealers), but there aren't going to be places where you can find a 90 Amp charger. J1772 goes up to 70 Amps AC mainly at the request of Tesla. To have Tesla up the spec of J1772 and then ignore it is just plain short sighted. J1772 has only 1 pin for communication, the other signal pin is merely a resistor to detect being plugged in, it replaces a magnet in the older Avcon plug.

Why is it such a big problem that Tesla gives their owners a choice between BOTH J1772 and their own higher performance connector? I could see you having a complaint if Tesla only gave their owners just the Tesla plug. But since Tesla owners can use EITHER ONE, I don't see the reason for outrage.
