I hope the ability to use your EV battery to backup your house power becomes an expected capability in the future. Glad Ford included it. Too bad Tesla backed away from it, i’m guessing due to their powerwall business.
If you have a small cabin with no a/c, wood heat, and a propane stove - your house is going to use hardly any power compared to your truck. It would barely make a difference.
The power draw is probably fine, but the contention for the battery would be a problem. Think, "hey honey, can we put off the Costco trip until next week so we can leave the internet up, and lights on?"
Implementing a transfer switch and dummy load just to dump solar generation when your truck is being a truck would feel like a weird exercise.
The mentality is extremely different, you do at home what you can, to the maximum.
But I need an HD truck, and it has to have enough range to tow, which means I'm not in the market for a Lightning. Dammit.
Ford's promo site says 'up to 10 days with rationing power' asuming 30kWh use per day with extended-range battery. But it's not clear to me if 30kWH is normal use, and rationing would be less, or if that's the rationed use. A 300 kWH battery seems rather large to me, and i haven't seen an actual spec for the Ford.
Edit: reread their site after reading sibling posts, in a different blurb they say 3 days or 10 days with rationing with the same assumption about 30 kWH per day; so their rationing assumption must be getting down closer to 9 kWH per day. Either way, a nice feature to have that would eliminate a portable generator for me.
So in theory, a fully charged Model X could power the average home for 3 days. Really puts into perspective how much energy is needed to move a car at highway speeds.
The F150 Lighting has up to a 150kWH battery, so somewhere in the 1-2 week range, depending on use.
