Here's the price for my residential electricity in Denmark for the next 24 hours: https://i.imgur.com/EER7bMP.png https://i.imgur.com/EER7bMP.png The light part of the graph is transport costs and taxes.

This is a standard tariff, there are other options for people owning electric cars. There's also an app to show this information, and (I assume) a way to tell the car to charge at the cheapest time in next few hours.
