CHAdeMO dead?

Neat

I am hopeful as this is through residential power company. I am trying to beg our local power company to do a pilot as well.

Tesla launching a ccs adapter.

No word on when/if its coming to the US, but if it does that will remove another leg of whats left of Chademo's future here.

SETEC already sells a $700 CCS1 adapter for the Tesla, and it is available in the US. The SETEC is 200 Amps; I hope the Tesla solution will be more.
One way or another, it is pretty much a done deal that Tesla owners will have CCS1 access.

----
Speculation:
I expect the Tesla solution for my 2018 model to require a hardware upgrade to allow adapter use*. If it's not much more than $1,000 I'm going to jump at the opportunity because it opens up the less traveled roads in Colorado my wife and I want to use. If the Tesla solution does not work out for us I'll buy the SETEC adapter.

*I'm going by the European experience. Tesla offered older car owners with Type 2 ports an upgrade path to CCS2 use via a hardware upgrade + adapter package. The package started out at 500 Euros in 2019 and now costs 300.

---
As for CHAdeMO, let me put it this way: If I was offered the adapter for free, I would choose to pay for CCS1 instead. The improved charging speed, and reliability that comes from using an actively supported infrastructure with much more deployment is easily worth the cost of admission.

Chademo wins huge IEEE award. CCS surely to concede and now vanish in face of this great honor:)

I just hope enough CHAdeMO cars are sold world-wide that someone creates a reliable VTG setup using it. It's not high on my needs list as if I ever needed anything like that I'd probably just buy a generator. Still the convenience of using a Leaf as solar backup while the grid was down (or up!) would be a nice feature.

There are tons of V2H units, just not sold in the US.

There were over 7000 V2H setups in Japan as of 2017. I've posted about V2x w/CHAdeMO numerous times like at the below.

It would be dangerous to feed back into the grid if the grid is down.

Dang! I had no idea there were so many options. But after a quick glance it appears most of them are not only not sold in the US, they don't support the US split phase electrical system. I guess I do remember some discussion on this but never paid attention to the details before.

And yes, I meant V2H not V2Grid. VTG is technically feasible and could work but the devil as usual is in the details, and the will to do it. It shouldn't be much different than grid-tied solar (during the day) except that the inverter input would be coming from a battery instead of a panel array.

There was also an Air Force Base test mentioned at viewtopic.php?p=576427#p576427.

Thanks for the link. I guess I knew that folks were working on this but somehow I hoped someone would come up with the perfect, albeit unrealistic, solution. It seems so easy until you start digging into the details.

There was someone posting just last week, IIRC, for a site that sells 3kw and 6kw V2H devices. AFAIK they are selling them in the US.
