Колко струва, ако един гост зарежда своя автомобил?

The costs are the number of kWh that the battery needs, multiplied by your own kWh rate. A car charging from half-empty to a full battery typically uses 25 to 30 kWh at a time, so at 30 cents per kWh you pay 9 euros per charging session, and with several charging sessions within a week this adds up to 20-30 euros. Since the electricity meter does not distinguish between household electricity and charging electricity, you typically only notice this at the annual meter reading. A separately metered charging point transfers these costs to the guest instead of to you, although this is only worthwhile if you regularly rent to guests with electric vehicles.
