if the blackout was a couple days or more, and you used your EV to power your house, what do you do when the EV is out of power? I usually keep a 5 gallon gas can around, but that type of thing might not work with an EV.
I doubt I'd use my EV to power my house any more than I'd use my current car to do so. If the power and natural gas went out and I had to rely on a generator to power my house, 5 gallons of gas would give me around 5 hours of heat from my heat pump, I'd need much more fuel to get me through an extended blackout.
Though I'm not sure why that's even a tradeoff... Even if you have an EV, you can still keep a 5 gallon can of gas to power a generator. Though if I were really worried about it, I'd probably get a 120 gallon Propane tank installed and use it to run a generator and maybe an auxiliary heat source like a gas fireplace in the house. That'd give around 80 hours of generator runtime (or longer if I don't need to run the heat pump) and propane doesn't degrade over time like gasoline.
Or maybe just skip the generator and go with solar on the roof and a Tesla Powerwall to power the house.
But in reality, since I park the RV near the house, if we had a blackout in severe weather, I'd just turn off the water and abandon the house and shelter in the RV assuming I couldn't just drive somewhere to get out of the power outage.
