Sort of. With my Kia EV9 I can use a V2L adapter to run an extension cord for essential items in my home. I understand in other markets there is a V2H connector so you can connect it to your home mains power but I don’t think it’s available in the US
Yes, I used mine in July 2024 to power my fridge and a couple of items when I lost power in Texas. Unfortunately the V2H requires a setup that I don't have.
