Market prices and "smart" chargers

[mortify]

That can encourage it, but people will need to charge even when it's not windy. Having a smart charger wait for cheap electricity which may never come is a great way to end up with dead battery.

[ZeroGravitas]

Smart chargers can predict weather, demand, carbon, price for the coming hours, they don't need to be entirely reactive.

There's various APIs you can check to see these predictions

That's not too smart then. I'm talking about something with a bag of weighted goals. Having a dead battery would have a strong enough cost that it would pay more for higher market rates if state of charge is low.
