Really? Setting up a pure sine wave inverter 48VDC to 115VAC/60Hz (or 220VAC/50Hz) is all one would need to do to supply single-phase mains to a home via EV? I guess it could depend a lot on the rated current capacity of the circuitry between the EV's Li-Ion main bank and the 48VDC secondary battery.
As an example, https://arstechnica.com/gadgets/2025/03/old-bolt-new-tricks-making-an-ev-into-a-backup-power-station-with-an-inverter/
12vdc for a Chevy bolt, with the caveat that it maxes at 1500w so only use a 1000w inverter.
It’s not a great way to do it, but it does work.
1kW ain't too bad for a short emergency. I was bummed when I found out the Greenworks 80V inverter maxed out at only 300W, since I had a nice collection of 80V yard equipment batteries.
Well, when you know you’re sitting on ~60kw of battery, it’s a bummer. The reverse feed system some cars have is promising though.
Vehicle-To-Load should be a blitheringly obvious feature for any electric car, and the fact that you have to go out of your way to even find a model with it should frankly be considered a cardinal sin of the whole fucking industry.
Like holy shit, all electric cars are effectively just powerwalls with wheels, this alone is such a big deal that anyone living even remotely rurally (including a lot of american suburbs) should be clamoring to get one since it would let you get through a multi-day power outage without losing all the food in your fridge and being able to power things like computers and phones. And you can even theoretically drive to the nearest place with power to charge your car, then bring that charge back home!
but no, implementing V2L is slightly more expensive thus they only bother on some models, and of course no government anywhere can be bothered to even politely request that companies implement it in all models..
That blows, they've got 500w inverters for the 24v & 40v batteries, but only 300w for the 80v
