to game it out, days before a major storm event you are likely driving around buying all the supplies you need, so yes, you are probably coming home with a low charge. if you live on L1, you generally aren't starting your day fully charged. I had a BEV for a few years. Speaking from experience.
Also, a 70 kWh battery ( attempting to pick a roughly avg number) needs 50 hrs to go from 0-100% at 1.4 kW. I was not starting from 0.
It sounds like you've got more experience with this, so fair enough! I'm assuming 50 miles for instance would be plenty to hit up everything you'd need, but if you're coming home with an empty battery, a level 1 definitely wouldn't be enough.
I had a 64 kWh BEV for a few years. After a normal commuting day I'd be ~25% and need 30+ hrs to fully charge. I notice these articles almost never acknowledge situations that aren't the ideal setup (e.g. ppl in condos and apts aren't likely to make use of V2L). Just preaching to the choir.
If the point is to help people who don't know much about EVs make an educated choice about what's best for them, then at least acknowledge these different situations.
