Most people charge their cars at night because utility companies incentivize to do so via time-of-use rate plans. There's nothing natural or convenient about delaying the charge until the middle of the night, what's most convenient is plugging in the car as soon as you park it.
Wind farms generate the most power at night, so that'll continue to work. If solar becomes dominant, then they'll make it cheaper to use electricity when the sun's still up, and we'll stop delaying charges until after sunset.
It's going to take decades to fully transition to electric vehicles, plenty of time to build all the renewables needed, all the storage needed for time shifting, and all the smarts needed for cars to participate in the smart grid.
