Has anyone seen any official comment from Nissan on this whole issue? Are they planning to start equipping Leafs destined for North America with this new charge port, or will they continue to use the Chademo?

I'm not convinced that it's possible to have both compatibility with existing J1772 on the new receptacle and for the new plug in the old receptacle. You can't count on space around the "old" receptacles for the extra contacts. The space available would vary from car to car.Devin said:What I don't like is that there doesn't appear to be backwards compatibility so you could get an AC charge from a L3 1772 plug if your car were not so equipped. It doesn't make sense to not make the ports compatible either way because at a charging station with 3 L2 EVSEs and 1 L3 charger you can still make use of all your charging equipment if 2 LEAFs and 2 Volts show up.

mitch672 said:Yes, you won't be able to use a new DC fast charger with the new connector to plug into your 2011 or 2012 Leaf, then again, the leases will be up on them by the time this is deployed anyway.

I plan to keep my Leaf a lot more than 2 or 3 years, so it would be nice if that CHAdeMO port was useful.
You are basically saying that everyone should lease a Leaf now because it is going to be obsoleted in 3 years?
(At least in terms of DC charging?)
The government funded EVproject is supposed to include public CHAdeMO stations. It is part of the reason I bought a Leaf in the first place.

Spies said:At this rate the EVproject is never going to get DC charging statistics from the program at least in my area before the program expires and will result in a complete waste of the funds already spent.
Actually, they will because your RFID card will still be registered to you for public charging, and even if the home part of the project is over, unless you purposely unplug the net just to spite them, your home charging stats will still be collected on your account as well.Spies said:...At this rate the EVproject is never going to get DC charging statistics from the program at least in my area before the program expires and will result in a complete waste of the funds already spent...
I think the goal is not backwards compatibility on the plug side, but compatibility with both plugs on the vehicle side.Devin said:What I don't like is that there doesn't appear to be backwards compatibility so you could get an AC charge from a L3 1772 plug if your car were not so equipped.
You do make a point about being able to capture the DC charging data via use of the registered RFID card as long as those chargers are in the EVproject but it would still require roll out of CHAdeMO chargers in order to do it at a minimum or that J1772 DC is is somehow backward compatible. If either of these things don't happen it will still turn out to be a wasteful investment from my perspective.davewill said:Actually, they will because your RFID card will still be registered to you for public charging, and even if the home part of the project is over, unless you purposely unplug the net just to spite them, your home charging stats will still be collected on your account as well.
Yeah, I like the idea of one connector to rule them all. Let's just hope we don't have a repeat of the Magnecharge SPI vs. LPI thing.Packet said:This at least gives you one plug on the vehicle side, where you can plug in an existing L2 J1772 plug OR the new L3 J1772 plug. Is it ideal? No. But I can see the SAE's desire to have just one type of connector on the cars.Devin said:What I don't like is that there doesn't appear to be backwards compatibility so you could get an AC charge from a L3 1772 plug if your car were not so equipped.
jcesare said:A few notes on today's event and a summary of the conversations I had with reps from Ecotailty and SDG&E.
- They handed out RFID cards at the event.
- The Blink RFID cards will be in the mail by next week.
- The EVSEs will be free until the end of the year.
- You need a card to activate the free charge. I used the EVSE after the event was over and I needed to swipe the EVSE to activate it.
- Before the end of the year you will need to give credit card info to activate your card.
- The card will not work like Chargepoint where you need to add a minimum $25 credit to the card, you will instead be billed on your actual usage.
- The charging rate is not yet set in stone. They are thinking of giving a frequent user discount or some other incentive. This will be worked out before the end of the year.
- They plan to add a charger reservation system and a mobil app.
- The QC CHAdeMO socket is being objected to by the Detroit manufactuers. They want the same footprint as the J1772 socket so they can utilize the existing openings on the side of the Volt and Focus. The other factor that is a concern is ADA compliance as it pertains to the weight of the CHAdeMO cable. They want the QC cable to be as lightweight as possible.
- 49 Leafs were at the event. Impressive!
...Developments in the next 12 months will determine which standard becomes dominant in the United States. If sufficient Leaf and CHAdeMO charger deployments occur, then CHAdeMO can become a de facto standard. On the other hand, if SAE finalizes the combo connector quickly, and if a major OEM such as GM or Ford rolls out vehicles with the combo connector soon, then it might displace CHAdeMO. Ironically, GM is leading the standardization effort for this combo connector, but their upcoming Volt does not have (or critically need) a DC fast charging port because GM included a gas engine for extending range. So, Ford’s early support of the combo connector is probably key if SAE is to have its way...
TEG said:Any news from Ford? No combo socket on the Volt? How about on the Focus EV?
This is taking longer to get sorted out and settled than many were predicting.
