why would you want to share your EV battery capacity with the grid? I don't understand this. Range is entirely dictated by your EV capacity and you're going to "rent" back the capacity (and battery cycles) for night time hours? I don't understand how this would work at scale.

Because you'd get paid for it, and you like free money.

And it should be pretty trivial to set an option to ensure you always have the necessary range for your daily commute by a little bit before you leave your home.

if services like Uber have shown anything, its that you can sell your vehicle's intrinsic value, depreciating it's value in the process. But will you be net positive after depreciated value?

Because a battery will become a lot cheaper and replacing it sooner will still have huge benefits for you financially.

I have a 100kWh battery and can drive with this 3 weeks around without charging at all.

Why would i not want to leverage this?

And results from storage systems show that you can charge and discarge car batteries a lot more often without real degeneration when you do this a lot more stable than when driving.

Also it reduces the overall straine to the power grid. If you fill your cars battery with local solar, you are transporting less energy across the whole grid. If you discharge it locally, again less overall energy which needs to be transfered across the whole grid.

How this would work at scale? easy: in my city for example there is one local power company and they offer a charging solution for my EV. They have a few powerplants locally here too. They have everything they need.

Also overall solar energy prediction for the next day is very good. You can easily save a lot of money by leveraging this up front.
