FWIW, I'm not a Tesla owner so this is more for educational purposes for me.
Tesla is a big fan of e-fuse so I would expect them to use that at the very least.
Where else do they use the e-Fuse?
I guess you're saying that EV manufacturers in general should put any components that can be nuked by V2X in a readily serviceable location.
There could be some market pressure for Tesla to do some of this stuff.
Lucid is shipping (or will soon send early access units) a bidirectional DC DC (? not sure about architecture ie DC vs AC, but I believe they have a 800V traction battery so they anyway need an onboard DC-DC for compatibility with 400V infra) setup for buddy (rescue?) charging between EVs. There's not much difference between a bidirectional DC DC capability on a car for buddy charging, vs DC coupled V2X.
Bidirectional OBC (well, I don't know if it's literally bidirectional OBC, but there's a 20A inverter in one of the modules) is on E-GMP cars already. For 230V markets this works OK as a 3000W V2H/V2L. I'm bummed that it's 120V only in the US, haven't tried it on my car yet.
If there are Tesla solar competitors that have V2X then there would be pressure for Tesla to roll something out. And they already have the expertise/pressure on external suppliers on the power conversion part of the external DC-DC charger.
