Thanks for the link.I agree, 400 volt is not the issue but it looks like they are redeveloping the entire stack. This is the article I was referencing.
Again I would love to be wrong but appears the odds are against it.
So it seems they mention a bunch of components that are coming with 800v arch as being bi-directional, not that 400v cant do CCS V2H.
They say an onboard charger (which all EVs have), DC to DC converter (seems like that could be done externally as long as it's in the CCS spec voltage?), DC to AC converter (inverter, done externally for CCS V2H).
I think maybe it's a misreading that this implies current 400v arch can never do bi-directional. I think they were just enumerating the things the new 800v architecture will (also) have. This list would be the same for the current 400v I think.
But this article that supposedly quotes Rivian sounds pretty clear to me:
https://techcrunch.com/2022/04/28/are-bidirectional-ev-chargers-ready-for-the-home-market/
āAll R1T and R1S vehicles have vehicle-to-vehicle (V2V) and vehicle-to-home (V2H) capabilities. While bidirectional charging capabilities exist in Rivian vehicles, regulatory and other regional variables are a significant factor for potential future V2G applications.ā
As far as I have seen Rivian announced they are working on a wall "charger" (EVSE) that will enable bi-directional charging (V2X over CCS DC pins). And I think they will be adding components in the trucks to do more, like a 240v outlet (like the lightning)
But I dont think it needs any of those things internally to do V2H. I havent be able to find anyone to say what about the current hardware would not work.
See a previous discussion here:

And see here where RJ says this will be possible:
https://stories.rivian.com/lets-just-drive (scroll down to the longer video, discussion is around minute 14) Note he talks about a V2V box and a V2H box coming soon and describes them as being external.
