I'm afraid what they're thinking is that if they can use standards confusion to slow down adoption of CHAdeMO then they can slow down adoption of Nissan and Mitsubishi EV's, until Detroit has some EV's to compete. Then eventually some of the Detroit EV's will begin to be offered with SAE compatible quick charging ports.GeekEV said:Are you suggesting that they would come up with another DIFFERENT connector that consolidate and replace both the current L1/2 J1772 plug *and* the CHADEMO DC plug? I can see then wanting to consolidate plugs, but to do so with a new design and NOT the already standardized J1772 would be absolute lunacy. Let's hope THAT's not what they're thinking.
That would be a smart thing for the SAE to do, even smarter would be to just adopt CHAdeMO without any changes. Since it's the smart thing to do though, it means it probably won't happen, but we won't know for another 7-10 years (that's about how long it will take for them to decide on Level 3 DC charging).rumpole said:I'm confused. No matter what new standard SAE comes up with, won't one be able to make an adapter to fit CHAdeMO? I would be surprised if the new standard includes some sort of active communication protocol, since that would just bog down deployment further, and therefore GM et al. would be shooting themselves in the foot, while Nissan and the other CHAdeMO makers would be burning rubber. The beauty of what Nissan has done is that they essentially own the Level 3 market by actually selling product and creating market momentum.
It's not a Betamax vs. VHS war since there is no Betamax. CHAdeMO is the de-facto VHS until something else shows up, and the SAE is still many years away from finalizing a standard.garygid said:Another Beta vs. VHS war?
Several manufacturers are busy building CHAdeMO's even now. Even as SAE and GM continue to try to put the brakes on EV developement, the CHAdeMO's are coming. Apparenty SAE and GM can even screw up trying to screw up others.walterbays said:I'm afraid what they're thinking is that if they can use standards confusion to slow down adoption of CHAdeMO then they can slow down adoption of Nissan and Mitsubishi EV's, until Detroit has some EV's to compete.

I hope they're dreaming, and by the time the first car hits the pavement that can use an SAE quick charging connector there are already thousands of CHAdeMO quick charging stations in place.
Standard is supposed to be finalized 1st quarter of 2012.DarkStar said:SAE is still many years away from finalizing a standard.
You've got it. That's exactly the idea -- one plug that can handle either L1, L2, or DC charging. They'll probably use the existing communication pins. Completely disagree that two plugs are better or less confusing. One plug is way more flexible from a design perspective. As for being confusing for consumers, if there are two plugs then you have to know which one to use. With only one plug you don't ever have to think about it. You push it on and any of the three will work.GeekEV said:I get it. So they're suggesting a coaxial plug arrangement with a J1772 in the middle and a larger plug with extra DC pins on the outside. That makes some sense, although I could see it confusing consumers who look at the small plug and the big socket and think "they don't match"... I'd rather have two for clarity's sake.
I'll believe it when I see it. What we know today as J1772-2010 (the plug update from AVCON) took a lot longer than a year.drees said:Standard is supposed to be finalized 1st quarter of 2012.DarkStar said:SAE is still many years away from finalizing a standard.
FYI, Oregon's 2nd publicly accessible CHAdeMO DC Quick Charger (Eaton brand) is opening on Tuesday.garygid said:There are 2 Chademo QC installed in CA, one actually working, which can be unlocked on polite request in person.
