Will companies adopt the Tesla NACS and drop CCS?

With Tesla opening up its patents on the Tesla connector over a month back, do we think companies will adopt the Tesla NACS and drop CCS?

Also, what would it take to build a high-amperage Tesla NACS to CCS connector? I know there are a few companies making a CCS to NACS (including Tesla), but nothing going back the other way.

It doesn't sound like the industry is eager to move over.

https://www.charin.global/news/char...-to-open-the-north-america-charging-standard/
CharIN applauds Tesla for including DIN 70121 and ISO 15118-02 communication standards for the NACS proposal. We also appreciate Tesla’s effort to move the e-mobility market forward even faster than it is moving now.

However, we encourage stakeholders to investigate ways to focus on market acceleration rather than the creation of yet another form factor alternative, which will lead to further consumer confusion and delay EV adoption. CCS has gone through many years of rigorous standardization processes, which is a required activity for any new standard proposal. After a decade of collaborative work, the domestic and international EV industry has aligned around CCS.

Too bad Tesla didn't do this 5 to 10 years ago. You'll never get the industry to adopt it now. Too much has been invested in CCS.

Discussed several times already.

No. No one is moving to Tesla's standard.

Probably would need some sort of cooling for a DCFC adapter from Tesla NACS to CCS. There are solid state cooling mechanisms, but probably pretty bulky overall.

Probably not. If the adapter is short enough there should be negligible resistance, and probably decent conductive cooling to the existing connector.

The wire from your vehicle's charging port to the battery typically isn't cooled either.

The Tesla Connector is like Betamax. It's technologically superior but they blew their opportunity for it to be the standard.
Is it though? It seems like the bulk of the benefit is purely aesthetic, and the remainder is reserved for a theoretical future.

Also, IMO, sharing pins for AC and DC is a net negative that opens the door to destroying hardware through software bugs or contactor failures.

Also also, it doesn't seem NACS supports V2H.

That's the thing - it's superior for a more closed set of application. Lower voltages, shorter cords, accepting higher hardware temps, etc.

Even that is farther than I'm willing to go. In fact, I've been reading more since I posted earlier, and I think that at this point I'm comfortable saying that unless you need it because it's the only connector on your vehicle, it's just straight up worse than CCS.

Also remember that the biggest part of the Tesla experience is in the software. The Tesla connector uses a different protocol. That's not being offered up, just the connector.

This is exactly what I've been telling people.. at least those of us who were around and aware of it in the beta vs VHS days. All too often the better standard is left behind in favor of what we already have or what is more convenient at the time.

CCS is just fine. Tesla is technically superior and more elegant, but in the end it's not going to make one bit of difference to Joe Consumer. People will have to buy adapters for a while. Some companies, most likely just Tesla, will incorporate both plugs on their upcoming vehicles. Eventually everything will be the same or perhaps changed to a new universal standard in the next decade or two or three.

No. Too much inertia for CCS. Remember Betamax and VHS? (yeah, I see now someone already said this)
