What is the use case for an EV to provide power to the grid?

Peak times vs. off peak.

This makes sense to me.

Charge car overnight offpeak costs, power house during peak hours

Here’s one scenario: Go to work with a partial charge, charge during the day using excess solar production when electricity is super cheap, drive home fully charged, sell some power to the grid during peak domestic use hours, keep enough to safely get back to work, repeat.

The highest few hours of peak demand each year. It can make sense to use relatively expensive storage for that because you're using it infrequently.

The use case (as opposed to public transit and stationary grid batteries) is that rich people get to feel good about themselves while still being subsidized by and separated from the working class.
