That's pretty similar to this idea, which I already mentioned: > People talk about EVs putting power back into the grid. Frankly I think that's a pipe dream in the near future. Our power companies are barely competent enough to run the grid without causing forest fires -- they aren't going to be capable of implementing that at the kind of scale that would make a difference anytime soon. It's not realistic to expect a…

Then everyone‘s charger decides „now is the time“ and the grid gets overloaded

or coordinate them so that doesn’t happen?

> many homes need retrofitting to be able to charge an EV FWIW 1kW for 8 hours is ~50km which is enough for most daily drives > I need my electrical panel replaced How much is that, really? Panel itself cost nothing, just some labour which I take is very expensive. You are improving your house tho and cost is likely negligible compared to car cost. FWIW it cost us ~$500 (eastern europe) to get 7kW charger purchased +…

I'd say that plugging in a car should mean - charge it enough to get me to a hospital. Beyond that wait for the optimum charge time. However there should also be a screen that overrides this if you are going on a trip or something.

Yup, let the tech overlords plan your life for you for the greater good. Fuck that fishing trip - your energy company decided you’re not important enough to have a charged car.

I don't know about that. Consider after a natural disaster, like Florida right now, or Texas last year. If every vehicle is low on energy (say, by trying to flee), and they are all trying at once to charge, that may overwhelm the grid. V2G only works assuming mass numbers of people aren't driving all at once, or trying to recharge their vehicles all at once. The fail condition needs to be: What happens if 80% of EV o…

If a civilization has already decided that adequate base-load supply is optional (which we apparently have…) — then at least making that inadequate Grid more resilient by adding more battery-to-grid capacity is an improvement. I personally this that’s stupid, but old slobs like me have been out-voted by young bucks who evidently don’t mind freezing in the dark.
