Correct. When you don’t use a mobile connector and instead use a hardwired connector with its own J1772 handle, it will have been configured to know the maximum amperage it can give to the vehicle. And there is indeed a simple communications link that tells the vehicle what that maximum amperage...
Nope, they recognize the strategic win here. Also, by far most EVs are Tesla anyways, so there won’t be the massive overload you think there will be. Also Tesla is building out a new site or more every day right now, so they are expanding at crazy pace.
Honestly I wouldn’t have expected an old Juicebox to load balance at all. Things can be missed or misunderstood when talking on the phone. Refer to manuals when trying to do complicated things like load sharing. If the manuals don’t provide instructions then it is safe to assume it can’t be done.
IMHO all vehicles should have 240V/30A offtake as an option for this reason. That's about the same or better power level as a typical portable standby generator. Currently, the only vehicle that can do this if the F150 Lightning.
Even a smaller EV can pump out the full 240V/30A for 5+ hours...
Um, except that CCS2 is a three phase standard and CCS1 is single phase, so the wiring harness and on board chargers are different? Oh, and CC2 has a car side mechanical interlock while CCS1 does not? So, yeah, the same, except where they are quite different.
Ugh! Too bad the builder is behind in asking you about the EV wiring, electricians do not like having to deal with insulation and I don’t blame them.
No, I would not recommend a sub panel, no need.
Running conduit is possible, using 6 gauge THHN wire, but I’m going to stick with my 6/2 MC...
Tell your builder that you are posting exactly how much they are (over) charging for a routine circuit installation on social media. Maybe they won't overcharge you as much if you do that.
The Rivian charger is fine, its what I also have. I prefer the Tesla one though (I have both).
Is it a custom home or a large builder like Lennar?
Those are really weird options, and no way should anything come to $4000 for a new home construction, that's ridiculous.
First, you want copper. Tell the electrician you want to hardwire a 240V/60A connection. Easiest way for an electrician...
There’s a lot of posts talking about CCS is Europe. The Europe CCS2 is completely different from CCS1 in NA. And irrelevant anyways. People as a rule do not move personal cars across oceans, so whatever they have in Europe (and China, and Japan) has no bearing on what we use in North America.
If you work out the economics of a charging network, you find that making money from one is very, very hard. It was estimated that in the early few years of the Supercharger network, Tesla was spending about $2,000 per car building out the network, and it wasn’t at all clear they could ever be...
Yes, CCS1 was always tenuous in NA since it was always way behind NACS is the number of charging stalls, in reliability, and in premier locations.
CCS1 made a bunch of early bad decisions (what can you expect from a committee?). The exterior latch gave it poor physical reliability. The lack of...
I’ve always thought Rivian’s RAN was a waste of money and now doubly so. It wasn’t needed in the first place, and now they are going to be stranded assets.
In the heels of Ford's announcement, Mary Bara is doing a Twitter spaces with Elon and announced this.

Updated with Munro begging Rivian to switch to NACS as well:
I still haven’t gotten around to taking it to the service center. I just got a recall notice, but no timeline yet, so I’ll mention it when I take it in for the recall.
