> EDIT: And I'll note - you can't just pile all those electric cars into any calculation and say "these are free to have". They're not. I'm not selling you cycles on my electric car battery - why would I? I can barely make money on the cheapest stationary batteries I can find in the market, and my EV battery costs a lot more then that. It doesn't matter how many are made, you don't own them. They exist to run vehicles people want to use.
The term you are looking for is demand response, it has the same effect on the grid as V2G.
With a variable rate contract it is cheaper for you to charge your car either at night or when the sun is out because energy is more abundant. Or even skip charging for a day unless truly needed because the prices are high.
- XorNot 3y agoThis is completely divorced from what I wrote. The point is that assuming you can simply take capacity in EV batteries, and use it as part of your grid storage is absurd and uneconomical. Again: I'm not selling you cycles on my battery because they cost more to provide then the electricity is worth. The idea that I might modify my charging behavior based on price is quite separate. The point is you don't have electric vehicle capacity available to run the grid - you have disconnectable loads at best. And they're not that disconnectable: after all, if all cars are electric, then all logistics is electric, and a huge amount of that is no longer optional load - it needs to run day in, day out.
