By now, we know that transitioning from a traditional combustion engine car to an electric one has benefits in terms of ecological footprint, both in the city and in the air ecosystem, as it has fewer emissions and particles. However, while we have a rough idea of the fuel consumption for gasoline cars, the plug-in factor for charging may not give an accurate idea of what happens with an electric vehicle (EV).

Let’s try to shed some light on this by calculating the consumption of an electric car. We will use data calculated according to the WLTP (Worldwide Harmonised Light-Duty Vehicles Test Procedure) standards, which are European parameters that reveal how much a car consumes through a series of tests conducted under specific conditions that are the same for all models.

The consumption of an electric car is expressed in kWh/100 km, like kilometers per hour but obviously related to the current. Each car has a different consumption, just like combustion engine cars, which can vary depending on factors such as batteries, weight, assembly, etc.

The average consumption of an electric car is around 13.5 kWh/100 km, but to determine the average consumption of an electric car, certain aspects need to be considered, such as residual charge and battery capacity. The reference is often made to the “20% to 80% charge” because it is not recommended to go below that threshold. Therefore, considering an electric car with an average battery capacity of 50 kWh, approximately 30 kWh of electricity would be used to go from 20% to 80%.

Assuming an average range of 400 km, you can travel 8 km per kWh. If the average cost per kWh is 0.50 euros, you can travel about 32 km for 2 euros. Taking into account the price of gasoline, which currently can be close to 2 euros per liter or considering a car with an average mileage of 15 km per liter, with the same expense, an electric car can cover twice the distance of a combustion engine vehicle.

Based on data from Sorgenia, the average cost can reach around 20 euros (with a range of 16 to 31 euros), while the domestic charging, depending on the voltage used, can cost around 8-9 euros, a figure that can be reached and further reduced if you have a photovoltaic system to channel the energy.

Comparing it to a traditional combustion engine car, starting with the previously chosen 2 euros, we are talking about a “full tank” cost that can range from 50 to 100 euros depending on the car. Even if we want to lower the price to 1.80 euros, it is still more affordable. What is considered expensive for most citizens is the price of electric vehicles, unless they have the support of some government subsidies.
