How much has the "full" of electric cars increased

The price increases for recharging electric cars have not followed in a linear fashion those for fuel. Let’s analyze the reasons

Over the past few months we have witnessed to the exponential increase in the prices of gasoline and diesel, with values ​​that last March touched 2.112 euros for diesel and 2.137 for green. This increase was partially calmed by the intervention of the Italian government, which provided for the cut in excise duties at least until July 8. Despite this, in recent weeks, prices have risen again, with petrol and diesel once again close to the physiological threshold of 2 euros. Specifically, according to the Mise observatory, the average price updated to 6 June 2022 of petrol and diesel in self mode, is respectively around 1,970 euros / liter and 1,879 euros / liter. The reasons for this bullish trend are many and range from simple speculation to the war between Russia and Ukraine, without forgetting the increase in the price of oil per barrel. In virtue of this context, many have taken advantage of the current incentives to buy an electric car. But even battery-powered cars have experienced increases in the price of various refills. Let’s see how the situation has changed in recent months.

Has the electric tank increased?

The Enel X tariffs, to which more or less all are aligned, have gone from 0.45 to 0.58 euros / kWh (AC, i.e. alternating current, up to 22 kW of power) and from 0.50 to 0.68 for DC (direct current) up to 100 kW; therefore € 0.75 for DC up to 150 kW and € 0.79 / kWh for ultra fast with power over 150 kW. There have therefore been increases, especially in AC recharges, but they have not been as substantial. Furthermore, it must be remembered that electricity in Italy has risen well over 50%. What does this mean? Some deductions can be made by assuming that most of the cost of refueling the electric car it is not directly related to the price of electricity but to the depreciation of the plant, especially in the case of ultrafast stations.

Ac, DC or ultrafast?

To better understand the context of the electricity market, we exchanged a few words with Gianni Catalfamo, nuclear engineer and CEO of OneWedge, a startup that deals with charging systems for corporate fleets: “The reason why the cost of electricity supply at low power in alternating current has increased proportionally much more than in the case of fast or ultrafast recharges, it is to be found in the fact that in the latter case they are essentially determined by the depreciation cost of the system while the energy component has a reduced weight , while in the case of low-power stations the ratio is reversed. Therefore the effect of the increase in kWh is much more sensitive on low-power stations “.

question of power

It is often common to read controversy over the tariff of the ultra fast Ionity network which is 0.79 euros per kWh. A high cost but to get it down to 0.35 per kWh it is sufficient to subscribe to a subscription of 17.99 euros per month. So yes, ultra fast top-ups cost money but there is no shortage of opportunities to bring the price down. Then there is another question that is not taken into consideration; this type of charging has been designed exclusively for long-range travel, so it makes absolutely no sense to use an Hpc in the city. The ideal context is to recharge the electric car at home, inside your garage, at lower powers and to use the ultra fast only if strictly necessary.
