Powering a couple appliances for a few hours is nothing for a car battery, those things are huge and powerful because cars are so inefficient. That’s not to say that V2G or V2X will work perfectly for everybody, but with the average commute around 25 miles and plenty of EVs out there over 200 mile range (which equates to mutliple days of typical electrical usage), there’s certainly some extra capacity. If you were compensated for the power you sold back at peak times, it could help justify paying for and lugging around the kind of battery capacity that is specced for your weekend/holiday road trips just to make your likely shorter daily commute. I’m using you generically, I don’t know your specific situation, so you certainly could be someone who would not feel a need to engage in that kind of scheme
