Here we have both free-market electricity plan and a a base plan, a remnant of when there was only one public electricity provider. The government every three months recalculate the electricity costs. In most cases for a flat it’s the more convenient plan.
Normally people have a peak power of 3 kW, some people have 6 kW on bigger houses. For more than 6 kW you can have only three-phase and so on.
More maximum power, more expensive the plan both for the monthly fee and the power consumed.
So if you get a 16 kW three-phase contract you will be going to pay electricity a lot more.
Free market plans are a bit different, but anyway going to a 3 kW 1-phase to a 3-phase contract to charge the car will be more expensive.
