Actually yes one thing I didn't consider in my calculation is the fridge (mostly because it's a spiky load that rarely comes on and I based it off my own apartment's instantaneous consumption at the time which was ~100W since the fridge compressor wasn't running).

Indeed with the fridge it pushes it a bit. But to address some of your other points:

> it would probably need to cool the battery

I'd expect if you're in a storm then you probably don't need any cooling - not to mention a 300W load is nothing for an EV battery compared to actually moving the vehicle. I'd expect some computers in the vehicle to be alive but that should be a ~10-20W draw.

On the other hand, my calculation assumes ~300W continuous. I expect the consumption to lean into the evenings due to the extra lighting, and drop off during other times.

But yes 80kWh might very well be what the OP has; I intentionally picked 50kWh as the lowest option I found on a "<major ev brand> battery kwh" search.
