So if the French population switched to electric, we would need 38m x 800W = 30 gigawatts. We have 58 nuclear cores of ~1GW each as a comparison (80% of our energy) - with the upside that nuclear plants produce by night as much as by day, which causes a lot of issues, therefore 800W between 10pm and 6am might allow a much more efficient (and ecological) use of our nuclear energy.

Market-based pricing for electricity is a big thing for people who have electric cars. It'll become even bigger when vehicle-to-grid/house becomes viable in a large scale (The Ford F-150 Lightning has this feature).

Basically you can program your charger to charge the car when the electricity price is the cheapest and feed the energy back to your house (or the grid) when the price is high.

Taking the cost of battery wear into account, I'm not sure that would turn out profitable.

This is the exact place where used EV batteries will find a second life.

A 40kW car battery with 80% SoH might not be viable for EV use, but it's perfect as a battery for a solar cell system. Either at home or at a public charging station.

Yes, this should mean much more efficient use of both the grid and nuclear power, both can provide continuous fixed supply for 24 hours but have had to be overbuilt to match up with the demand curve, which up to now has been extremely uneven.
