Nissan Leaf Nismo RC Concept: New York Auto...
First 2011 Nissan Leaf Delivery, To Northern...
2011 Detroit Auto Show Preview: 2012 BYD e6...
So you bought a 2011 Nissan Leaf, and paid for the optional $700 quick-charge connector.
Now you're able to get an 80-percent battery recharge in just 30 minutes, albeit from very few places right now. Promising, right?
Not so fast, sonny. It appears that U.S. makers of electric cars are likely to adopt a completely different quick-charge standard, one that will be used solely in North America.
The likely standard won't be compatible with the "CHAdeMO" quick-charge hardware in your Leaf, or any of the other Asian electric cars that offer it.
So Nissan Leaf owners and those with other new electric vehicles that contain a CHAdeMO upgrade for fast charging may find themselves locked out of the U.S. rollout of such chargers.
Today, the 2011 Nissan Leaf, the 2011 Smart ForTwo Electric Drive, the upcoming 2012 Mitsubishi "i," and the 2011 Coda Sedan are equipped to charge at 110 Volts and 240 Volts with a universal connector.
That connector is usually known as J-1772, for the standard number assigned to it by the U.S.-based Society of Automotive Engineers (SAE).
On the 2011 Nissan Leaf, a second charge port called CHAdeMO is offered that permits DC high power charging, which gets the vehicle up to an 80-percent charge in 30 minutes or less.
In some areas, the Leaf quick-charge port is provided free as part of a national "EV Project" program. But most buyers pay the standard $700 accessory charge for that upgrade.
As of this month, only a single functional CHAdeMO charger exists anywhere in the United States. It's in Portland, Oregon, as reported by Rick Durst of Portland General Electric.
But in Japan, the CHAdeMO format is a national standard. More than 130 such recharging stations already have been installed (as shown on Google Maps for Japan), while the U.S. is still debating the adoption of a final quick-charge (or L3) format.
According to Adam Egbert of California electric utility Pacific Gas & Electric, the Underwriter's Laboratory has not yet certified the CHAdeMO charging station as an approved piece of hardware.
That's why the second such charging station in the country, in Vacaville, California, has been taken off-line by PG&E, which installed it just a few months ago as part of an early "test program."
Yesterday, Craig Childers of the California Air Resources Board (CARB), said it appears that the U.S. is strongly leaning toward adopting a non-CHAdeMO charge format quick charging electric and other plug-in vehicles.
That format will be based on an SAE recommendation that provides for a single, multi-function, interface built into the car, rather than the two separate plugs now present when a car has both the CHAdeMO and J-1772 connectors.
"Automotive companies are lobbying for only one opening for powering the car," Childers said, "to allow for cleaner design."
The SAE format has a J-1772 connector embedded in the center of a slightly larger array of input pins which would all be enclosed by the fast charge handle surround. It would provide the same 30-minute recharge to 80 percent of battery capacity.
While this is not yet a "done deal," according to Childers, it would mean that early CHAdeMO adopters would have to hope that their automaker would offer a retrofit for their vehicles if the new standard comes to pass.
So, for those Nissan Leaf owners who want to retain the ability to quick-charge their cars as they sit, this is the time to speak up.
Have an opinion?

Um, according to CHadEMO website, the numbers is way over 600.
Norbert Posted: 5/13/2011 1:34pm PDT
Until recently, it would have seemed that CHAdeMO is a possible choice. Why does this information reach us only from a CARB member?

Yes, also some of the fast-charger manufacturers have announced that their equipment can be retrofitted. (Although I'm not sure in how far this would apply to others.)
Doug Posted: 5/13/2011 3:13pm PDT
@eletruk "It may be nothing more than a receptacle change in the vehicle to switch to it."
Unfortunately it's not. CHAdeMO and the SAE proposal use different communication protocols. So some electronics would have to be exchanged as well.
'"Automotive companies are lobbying for only one opening for powering the car," Childers said, "to allow for cleaner design." '
Then they should have gone with this for the global standard: http://tinyurl.com/3zd37qw

For related interest, this appears to be a map for Japan's deployment ("CHAdeMO Nissan")

EVs are a great thing and the coming technology. It will be possible to convert CHadEMO chargers to the J1772 standard as there is no difference in the power capabilities, just the programming and connector. In fact both standards could be supported from one charger.
It is, by the way, a reference to a very famous line in "The Treasure of the Sierra Madre" from 1948: http://en.wikipedia.org/wiki/Stinking_badges

Yes, I got that utility wrong after always seeing it as PGE and then using our California area service as the translation. Thanks for the headsup on that.
@reader..
"600" is clearly consistent with "more than 130" as I noted, and in the Google maps representation I counted the locations up to around 80 and then was only about halfway through the country, so projected a "safe number."
@Roy H.
As John Voelcker recognizes the form of the headline that appeared was different than what I submitted, but we walk a fine line between getting a potential reader's attention and never having them link to the full article.
Thanks to all of you for your feedback....and interest.

The number of CHAdeMO DC Quick charger installed up to today is 747
-- (Japan 656 Europe 87 Other 4) last update 2011.5.12

Although I think some percentage of those are not public (but private fleet or so), I think this proves (more or less) that installing such a network is possible and practical, and it was apparently done in a relatively short amount of time.
George Parrott Posted: 5/14/2011 7:30pm PDT
Wow, that Japanese number certainly makes the US effort even more obviously ineffective and delayed.
One possible explanation for this US "delay" could well be that the suppliers here are waiting for that actual US final adoption before installing units only to have to retrofit them?
But as several have observed and my informants also suggest "it should be relatively easy to modify an installed CHAdeMO charger unit to another generally similar standard. But it would sure be nice to have more of those DC quick chargers around for the increasing number of Leaf and soon Mitsubishi "i" drivers.

The US car makers are oil sluts.

As DonC has noted, but I will try to make even more clear...The gas engine in the Volt is actually the "supplement" to the battery pack. For almost all of DonC's driving he has been totally electric powered. We make frequent trips between Sacramento and the south side of San Franciso with our Volt, and only the first 40 miles or so of those are fully electric, so we have a bit over 4000 miles on our red Volt and are at a cumulative 98 mpg. Yes, we have used some fuel, but only about half of what we would have used in our previous Prius, and virtually every daily drive around Sacramento is fully electric, so we contribute zip in the way of exhaust emissions into Sacramento's horrible air quality basin.

According to Dave Knox of Texas based NRG, neither of the "installed" CHAdeMO units ready to go in Texas are operational, as they are awaiting UL approval, as is the unit in Vacaville, CA. This was as of 5/16/2011 at 9:15am anyway.

What are the charging plugs in PT? Are they using IEC standard type 2?
en.wikipedia.org/wiki/VDE-AR-E_2623-2-2#Type_2_-_VDE-AR-E_2623-2-2
Type 2 provides both simple and fast charge in a single plug design.
Stan's Volt Posted: 5/17/2011 10:18am PDT
Most all days I drive for $1.90 electric Cost or less.
Going-Electric Posted: 5/18/2011 2:40am PDT
The plug is reasonably light and probably a lot cheaper and less bulky than the US design.
US industry was too slow and has therefore has missed the DC charging train.
Lets hope it will try to catch up with other innovations, instead of destroying the only workable DC charging standard...
Jim McL Posted: 5/18/2011 4:10pm PDT
Mr Parrott mentioned four EVs only two of which are actually available in the US. The Leaf has a long waiting list. The 4 year lease on the Smart ED costs more than purchasing the Th!nk outright with only the Federal tax credit. Performance of Smart ED and Th!nk is similar, but Th!nk has a cubic meter of cargo space.
What is with the omission?
www.thinkev-usa.com is shipping to all states now (at least the lower 48)
Norbert Posted: 5/18/2011 6:02pm PDT
Scheduled for 2012, the US-delivered Leaf as well as its battery will be assembled in Tennessee, if that matters to you.
Jim McL Posted: 5/18/2011 7:23pm PDT
But after all the problems we had with the Mini E (and don't get me wrong, we LOVED the Mini E) the factor that weighed most heavily was Th!nk's 20 years of experience with EVs and the reports from the thousands of generation 4 Th!nk drivers who say the Th!nk is the most reliable car they ever owned.
The no rust no dent no scratch plastic body panels made the Th!nk a slam dunk. My 15 year old Saturn has plastic body panels and looks great.

(Personally, I'm interested in Tesla's upcoming cars, but EV is EV. :)
Jim McL Posted: 5/19/2011 5:07am PDT
PS I've heard the chademo has a right to use of $2,500 and J plug is only $240 so I go for the no right to use fees!
