Depends, I guess, on several factors. They certainly have the expertise. Would they be able to build one for a significantly lower cost, would they want to be able to rely on their quality, and how much power will the Model S (and future cars) require to support its maximum charging speed? The first Model S rolling out of the factory might already push the envelope on currently *proposed* standards.Originally Posted by doug
Government announces £400m electric car scheme - Autoblog UK
Over the next 18 months, around 11,000 charging points are expected to be installed in streets, car parks and big supermarkets. This is on top of those already installed.
Plugs and CarsWho knew?The units I found quite accidentally are Free Juice Bar dual-connector units.Lots of mistakes will be made as public infrastructure is deployed. Charge stations will appear where cars don't. Bad siting or signage will lead to empty or ICEd spaces. And 240V charge stations will appear where 120V outlets would suffice. I've publicly pondered when the first J-plug would appear at an airport long-term parking lot, as there would seem to be little benefit to charging faster if the car is sitting for one or more days. If you're parking in a long term lot, your Tesla will fill up at 120V before you return.

Where Are the Promised Electric Vehicle Chargers? - voiceofsandiego.org: Letters
...The EV Project is a massive contract awarded to ECOtality by the U.S. Department of Energy (DOE) in August 2009 to install electric vehicle (EV) chargers throughout California and several other states. Although the DOE's grant was for $99.8 million, there was an additional grant of $15 million to expand the project, and the total public and private investment brings the total cost to approximately $230 million. The EV Project covers both in-home chargers and public chargers. While the in-home charger deployment is going well, they are failing on the public charger deployment...
Standard does not real matter. This can easily adapted later. What Elon mentioned is just moving the charger out of the Model S and make it a little bigger like 100kW instead of 20kW and therefore it needs to be DC. Or maybe at the charger-station there will be the chance to feed 5 Model S with AC 20kW or one with DC 100kW.

The Plugin America related people seem to be fond of 110 V (and low-amp 240V) charging. Maybe it's just me, but to me they seem stuck in the 90s or even before. Nissan is upgrading its 3.3 kW to 6.6 kW standard charging soon, and personally I'm sure it will take only a small number of years until even that is totally outdated, and all those low amp chargers will be considered a burden to be replaced. They reflect a limitation of current batteries, and the inertia of utilities, who are perhaps not yet confident that there will be the demand justifying more than the smallest investment. However they will be outdated faster than you can spell out PHEV.
Is this not what the J1772 DC standard proposes?

It's the consumer that will drive what these guys produce. I have been calling each of these manufacturers and telling them that I will buy their product (charge stations) when they are able to provide level II charging at 75 amps +. This tells them what their market will be. Everyone should do the same.

I would strongly dispute this. They have been driving EVs for 10 years and know how the Nissan 3.3 chargers are not only useless but damaging to the cause since new EV owners will be so disappointed. There are a few who are happy with anything but the techy ones all scream for 30 amp 220V min EVSEs.

I am glad to hear that (although it doesn't have to be screamed, it is just stating the obvious, in my mind). However the articles and videos which came to my attention so far, have been, unfortunately, quite consistent in this regard. Referring to the article you quoted, I'd wonder what the point would be of having the J1772 AC Level 2 standard for non-fast charging, if you then have to carry along 120V-outlet adapters all the time.
Airport long-term parking seems such an exception, and even there, if you have a 300 mile pack, and are just going on a short trip, coming back 48 hours later, 120V Outlets are probably already limiting the possible charge. J1772 EVSE's will surely come down in price, once the quantities are larger. The less expensive ones are already at $751, if not less. (In comparison, the Panasonic/Nissan 120V adapter is $508, according to Plug In America.)
Although the shown J1772 charging points look more expensive than that (yet charging is offered at no additional cost), I wonder why he has to complain about the only three J1772 charging points he could find. It's often more expensive to be the first, and usually the early options are limited. I'm all in favor of not making it a habit to buy super-expensive machines on tax payer cost, so I don't mind if he, in some context, raises that as a concern, but we have to start somewhere, and 120V outlets really aren't the better alternative. Also, in my mind, it would make EVs appear more like toys, than like a cost-effective yet serious alternative to ICEs. It would increase the perception (and actually, the reality) that EVs take long to charge.
