> Actual price of electricity is negligible, around 4-6 cent/kWh. There is really very little wiggle room here.

That's the average energy price, and what typically pay if you have fixed pricing per kWh, but there is lot of variance hourly/seasonally. Sometimes in the night time the price of energy can be almost nothing (e.g. hydro power reverses overfilling), but of course you still have to pay for grid company + taxes. To take advantage of that, you need a "market price" plan with your energy company. E.g. I try to store the cheap night-time energy into water boiler + floor heating.

An electric car is very good match for cheap nigh-time energy, as you typically charge overnight.
