The cost per 100 km of an electric car can vary depending on a number of factors, including the car model, driving conditions, driving style and the price of electricity. In general, the cost per kilometre of driving an electric car is lower than that of an internal combustion engine car because electricity is a cheaper fuel than petrol or diesel and electric cars are usually more efficient.

You can calculate the cost per 100 km as follows:

  1. Check the range of your electric car (for example, in kilowatt-hours - kWh). This information is usually available in the car's documentation or on the manufacturer's website.
  2. Look at the price of electricity (kilowatt-hour - kWh) in your area. You can find this information on your electricity supplier's bill or on their website.
  3. Multiply the electric car mileage (kWh) by the electricity price (kWh). This gives you the total cost per 100 km.

However, be aware that the real cost may vary depending on a number of variables such as temperature, road conditions, speed and the electricity consumption functions used (e.g. air conditioning, heating, etc.). Therefore, it is recommended to use the above calculation method to obtain an approximate cost and to take it into account as one of the factors when choosing an electric car.
