Oops. I completely missed that sentence."One or more DCFC charging port(s) may also have a permanently attached proprietary connector."

I never understood CHAdeMO, with its absolutely giant connector and no fewer than EIGHT signal wires. I'm not sure what those eight wires are for, but it seems to me that four would be way more than enough to communicate what needs to be communicated. I'd also wager that three or even two might be sufficient, with a little work. Heck, with wifi ZERO signal wires might be enough(although its probably quite a stretch, since you'd want to be able to tell which car was plugged in to a particular stall). You clearly don't want to accidentally energize a thousand volt DC connector without it being plugged into a vehicle. That said, it wouldn't be THAT hard to design a protocol that says "Hey, try 10V on the connector and we'll see if the car sees it. If not, lets try another connector"Oh yes they are, at least in California. California Air Resources Board denied them permission to discontinue it at new sites.

The EU apparently beat him to it.if Biden wants to do this, he should also make Apple put a USB-C port in iphones
Impossible? Never.There was an interesting article in this morning's Wall Street Journal with some issues that I don't think have been mentioned in this thread: in a lot of the country, particularly "the west", things are rural enough that even good ol' gas stations are more than 50 miles apart, sometimes with no electric service for large areas. How, then, can one meet a requirement of charging every 50 miles? There was mention of proposing roving charging trucks to rescue cars that hit zero. And, frankly, I don't remember if the 50 miles thing was administration rhetoric or if it was part of the law.
It also mentions that the 2015 "FAST Act" determines which highways should have chargers. Apparently this has two problems in some rural states: sometimes those highways aren't near people, and sometimes roads near people aren't covered by the FAST Act. Reading the article gave me no sense as to the size of that problem: is it a real problem? Or is it an incredibly miniscule thing being used for talking points by opposing politicians?
Here's the article, I'm a subscriber so no clue about paywalls.
Biden Plan for EV Chargers on Highways Meets Skepticism in Rural West
The U.S. government wants fast-charging stations for electric vehicles every 50 miles along major highways—and some Western states say the odds of making that work are as about remote as their rugged landscapes.www.wsj.com

It's Tesla's fault for keeping its connector proprietary, so now we are stuck with we have.All connectors should look like this...ok, I can dream.View attachment 817157

Similarly, it is the fault of the insignificant compliance EV producers for developing and sticking with CCS so we are now stuck with what we have (ie their drivers don't support, and can't benefit from, the only reliable reliable, and well-deployed charging network in the USA.It's Tesla's fault for keeping its connector proprietary, so now we are stuck with we have.
They did submit it to the SAE (owners of the standard at the time CCS was developed) but were rejected as the majority of the committee had no interest in a good charging standard, finishing the standard before Tesla's cars were ready for production, or supporting fast charging speeds suitable for road trips (50 kW was the target). You, as a newcomer, apparently swayed by the rhetoric of shills such as mockingbird, should not spout or parrot that about which you know nothing as you simply will create a false history.It could have been the standard connector but Tesla kept it proprietary so it isn’t.
They could have easily submitted the design to CharIN and had it formally designated a standard but that just didn’t happen.
Got a source on that? I've only ever seen the story of Tesla suing a European charging company early on trying to make their own supercharger using a reverse engineered port.They did submit it to the SAE (owners of the standard at the time CCS was developed) but were rejected as the majority of the committee had no interest in a good charging standard, finishing the standard before Tesla's cars were ready for production, or supporting fast charging speeds suitable for road trips (50 kW was the target).

There weren't reporters there. As an enthusiast, I was in meetings with folks from Tesla and other charging station vendors just afterwards where it was discussed.Got a source on that?

1. That's just an urban tale.They did submit it to the SAE (owners of the standard at the time CCS was developed) but were rejected as the majority of the committee had no interest in a good charging standard, finishing the standard before Tesla's cars were ready for production, or supporting fast charging speeds suitable for road trips (50 kW was the target).

60A single phase? I think not. All connectors should support 3 phase and DCFC with 4 power pins and a multiplexer on 2 of the pins for DC/AC switching. And such a connector does not yet exist.All connectors should look like this...ok, I can dream.View attachment 817157
yeah, I know all of that...just frustrated, sorry. From a design standpoint, it is superior and elegant.It could have been the standard connector but Tesla kept it proprietary so it isn’t.

Yes, they could have. But that would have made it harder to maintain quality control that was so important when opening up a new market against such hostile, powerful competitors (the ICE industry). Besides, given the reception they met at the committee, It wouldn't surprise me, nor would I hold it against them if they decided to go it alone - just for spite - "if you can't join 'em, beat 'em"2. Tesla could have made the specifications of the Tesla connector available to the public regardless of what SAE/ACEA did.
