SAE Quick Charge Connector Go

[scottf200]

No, I mean, the DC part of the connector would hit the volt's body below the charge port...Nate

It is a L3/DC charging plug only. If you went to a public/private charging station it would likely have two cords and two plugs (or they may be two chargers):
a) L3/DC charging J1772 combo (top and bottom)
b) L2 charging J1772 (top only)

Would appear the circled ones are the ones they combined. So top is diff but bottom is the same in the new plug.

With all due respect, DonC, I disagree. Public Level 2 charging is next to useless, because as you say most people who actually drive EVs charge almost exclusively at home. However, to say that EVs are not suited to long trips is misleading. A Tesla Model S with a 300 mile pack, and a reasonable network of 90kW chargers, will be a fine long distance car. As technology improves, specifically when 250 kW chargers hit the market for a reasonable price and battery prices become more reasonable for big packs (all things we know will happen over the next 5-10 years), EVs will make great long distance cars.

For $70K+Options you can get a Tesla Model S with a 200 mile battery. FYI demand charges in CA are roughly $25/kW, so charging one car at 250 kW would cost $6,250. That's a heck of an expensive charge.

"Most people will be perfectly happy to charge at home rather than spend $.50/kWh for the privilege of sitting at a public charger for and hour. AFAIK no one has come up with a business case for public charging, and, in the absence of a business case, public DC charging isn't happening anytime soon. (I spent $800 for one and I haven't ever SEEN one). "

Maybe you didnt read this, but the 'business case' isnt necessarily important if states get onboard with making it part of infrastructure. California and a few other places are starting to invest in QC infrastructure, and the cost for these stations is coming down quickly. There isnt much business case with any public charging, but thanks to government grants, they are being made available.

"That leaves Nissan, but with sales of 370 units a month it would be 100 years before there would be a sufficient number of EVs on the road to matter. "

That is a cheap shot. Nissan is unbelievably supply constrained right now. You can hardly find a dealership that has them. There is barely over 1,000 available in the U.S. for sale now. Compare that to more than 3 times of the already constrained Chevy Volt. The car will not be selling in the thousands per month in the U.S. anytime soon, but they will likely sell 10x what BMW and Ford do in a month. When the Tennessee plant opens up, I expect things to get better for them.

I don't think you can stick a fork in anything when the opposing players arent producing ANY pure EV vehicles at the moment in anything other than token amounts. Especially when the elephant in the room, California, is decided to install quick chargers to support the Leafs. By the time the SAE is formalized, several years will have likely passed, and hundreds if not thousands of chademo stations will be operational. Chademo is likely going not going away, with or without SAE.

[DonC]

California is most definitely not investing in DC charging. I think at the moment there is one, which is a mind bending number given that there have been federal funds which pay for the chargers and their installation. IOW you can't give these things away.

NRG settled a lawsuit in which, as a penalty for fixing electrical prices, it agreed to put in 200 DC chargers so long as it receives the money generated by the chargers. The first obvious question: What lunatic signed off on this? The second obvious question: How likely is it that this will ever happen? (These will have the SAE connector BTW).

FWIW I don't buy into the notion that the Leaf is supply constrained. It looks like it's demand constrained. I think Carla Bailo mostly admitted this when she said "we were constrained" (note past tense) and that "we're still bullish on EVs" (as in they haven't sold worth cr@p but we still think they will).

[CarZin]

Do you have something to counter this, which clearly states NRG is installing Chadmeo stations?

[DonC]

The NRG agreement is hardly set in stone. For the EV Project:

Number of DC Fast Chargers promised for San Diego: 30
Number of DC Fast Chargers installed in San Diego: 0

The settlement hasn't even been approved by the CPUC. Then we'll have a few years of appeals. Then very few if any DC chargers will get installed at which point they'll amend the agreement, assuming it ends up approved in the first place. This is like mandating sales of certain types of automobiles. If people don't want to buy them you can't sell them. Property owners don't want a DC charger. The obvious alternative is a government entity. They might be willing but they'll want to use federal funds for this purpose, and to use federal funds you have to use an open standard.

In this link:
"NRG is committing to support both current DC Fast Charging systems (CHADEMO) and the future system being standardized by the SAE committee. How this works out in practice is yet to be determined, and at worst NRG will have to install a second fast charging station supporting the SAE DC Fast Charging protocol alongside the existing CHADEMO stations."

In addition, Blink Networks has stated that they will supply both CHAdeMO and SAE plugs for their DC fast charging stations.

I don't think this is going to be a problem.

Dancing over the Level 3 discussion like an 800 pound ballerina is the issue of battery degradation with regular use. Who in their right mind would risk a $10,000 battery to save charge time? To my knowledge, no EV manufacturer has denied this risk. Occasional use is fine, but then how to pay for the special chargers and industrial grade electrical infrastructure.

As for the utility of Level 2 chargers, I know every charger location in town. I work, shop, and watch movies without burning a drop of terror fuel and without wasting my time. I call that utility.

[CarZin]

Honestly, the battery issue is all over the place. I have seen so experts state that it will have absolutely no impact on the battery whatsoever. I have also seen the opposite. Right now it is an unknown.

I see level 3 charging as a mobility enhancer. What California is doing will allow cars the opportunity to safely travel outside of their normal commuting pattern. The price to charge is reasonable, with the caveat that it isnt used daily.
