Maybe. The battery chemistry for a car vs stationary storage differs greatly. Stationary storage they optimised for ability to hold charge for long periods of time, and not loose capacity over time. Car batteries optimised for weight and charging speed. If you cycled your car battery every night with the grid it wouldn't last all that long. Maybe it won't make a difference in the long run with how many EVs we have though.

Most EVs charge daily. The idea is that you can update charging rate/time to match e.g. wind power output, which tends to peak late night/early morning. Dispatchable load is nearly as useful as dispatchable supply for balancing the grid. Discharging the battery to power the household would be a bad idea outside of emergencies, due to the capacity loss you note.

Tesla has a pilot program in the Netherlands.

My "ask" is that if you own an EV, and your employer isn't progressive about charging stations, politely prod them (there are usually incentives, find these!). My employer has an environmental progress initiative, and it only took a few emails for them to install a few Tesla and Clipper (non-manufacturer specific) chargers in our parking garage.
