The solution to this is going to be have customers enroll in smart charging. Keep your car connected to the smart charger when not in use and during times of excess power charge the car for a few cents per kw.

Then everyone‘s charger decides „now is the time“ and the grid gets overloaded

or coordinate them so that doesn’t happen?

You're describing dumb charging.

We have the means to balance grid usage by telling specific families at which time they should charge their vehicles.

I'd say that plugging in a car should mean - charge it enough to get me to a hospital. Beyond that wait for the optimum charge time. However there should also be a screen that overrides this if you are going on a trip or something.

Yup, let the tech overlords plan your life for you for the greater good. Fuck that fishing trip - your energy company decided you’re not important enough to have a charged car.

This assumes you can have your car plugged in during the day.

It people drive to work and cannot plug in their car, then most of the time it will only be plugged in at night.

Yeah. Adding complexity to a system is always the best solution.

Hopefully the ability to charge at work becomes more popular.

So, the solution to "the solution" is to allow the government to control more of the market? Who will enforce this? What will the penalties be?

Or, do we just raise power prices for everyone and then give them a break if they allow a third party device to restrict their power usage? Seems like a great way to subsidize "the solution" on the backs of people who can't afford a new EV of their own.

Also.. when are there times of "excess power?" The grid operator tracks demand and then orders power from stations, or it doesn't. There is "excess capacity" but that's set against not running the plant at all, so I'm not sure there's some "free lunch" to be had here.

Simple answer is just "congestion pricing". You want fast charging at peak hours, pay double. If not, set some price optimization. And set it to prioritize the first 30% of charge to never be stranded but always wait for cheaper power to fill to the top. If you've got a fishing trip, plan ahead or pay extra. That's just free markets.
