Rise in the price of Superchargers: cheaper to run on diesel than on electric?

Since electricity prices are indexed to gas prices, it didn’t take long for electric car charging prices to soar. This is particularly the case with Tesla Superchargers or Allego network fast charging stations.

For the moment, thanks to the tariff shield applied by the government, the price of electricity for individuals has increased “only” by 4% in 2022 and could increase by 15% in 2023. On the wholesale market , the price of the MWh rose from €85 in 2021 to €1,000 in September 2022. A stratospheric price increase that affects energy distributors.

40% increase

Thus, Allego, a specialist in terminals for electric vehicles which today claims to manage 28,000 public terminals in Europe (including 2,000 in France) not only increased its prices on September 1, but is already warning that there will be a increase in October. For a fast recharge at a power of 50 kW, it is necessary to count 0.69 €/kWh, and even 0.79 €/kWh on an ultra-fast terminal. That is an increase of €0.14. After October 7, the rates will respectively drop to €0.88 per kWh on a power terminal below 50 kW and €0.98 per kWh on terminals above 50 kW.

On the Tesla side, users received an email informing them that due to an increase in energy prices, Supercharger prices had to be adjusted. Thus, the tariff increase increases the tariff from €0.52 per kWh to €0.67 everywhere in France, while the charging price for vehicles from other manufacturers is now €0.79. For the moment, the Ionity price without subscription remains at €0.69 and €0.39 with the monthly subscription of €17.99.

Between the purchase cost on average higher than their thermal equivalent, a drop in the ecological bonus which will be reduced in 2023 and a rise in the price of fast charging, the wallet of drivers risks being hit quite hard. In addition, after a quick calculation, it should be noted that a motorway trip made in an electric car could end up costing more than the same trip made with a diesel thermal car.

Indeed, the consumption of a Citroën C5 Aicross Blue HDI is for example measured by our colleagues from Engine 1 6.1 l/100 km on the highway. The price of a liter of diesel is €1.75 to date.
To make a journey of 650 km for example, the total cost of the journey with the Citroën C5 Aircross will be 39.65 l x 1.75 € = 69.38 € by applying the government’s 30 ct pump discount; without the discount, the price would be €81.28.

On the side of electric vehicles to stay in the SUV category, we have chosen a Tesla Model Y Long Autonomy whose consumption on the highway noted by our colleagues from theAutomotive Magazine is 19kWh/100km. We have also chosen a Kia Niro EV whose consumption on the highway is 23.2 kWh/100 km (measured by us).

The results of our calculations are quite interesting. Taking into account a first recharge carried out at home with a start at 80% of the battery and a charge on the highway with a Tesla Model Y Long Autonomy, we obtain a cost of 60.58 €. On the other hand, with the same vehicle, the cost of the trip rises to €82.75 without recharging at home. On the side of a Kia Niro EV, if we put the odds on our side with a first recharge at home then a recharge on the Ionity network including the subscription, the amount rises to €64.97. On the other hand, the cost can very quickly rise to €76.56 under the same conditions, but excluding the Ionity subscription; or even €104.05 if you only rely on the Ionity network for this journey. Worse still, it will take €119.13 if you recharge only on the Superchargers network; which of course would be nonsense, but the calculation allows at least to bring it to light.

Results to be put into perspective of use

These results should be interpreted with caution insofar as the first charge of the electric vehicle will take place in the vast majority of cases at home, where the amount per kWh is currently at €0.17. Finally, and as we emphasize throughout our tests, the motorway journey is the least favorable to electric vehicles insofar as the mass of the latter, their air resistance and the little use of regenerative braking melt the battery in no time.

In any case, before rushing to buy a vehicle, we advise you to think about the use you will have of it and the way in which you will be led to recharge it; slow charges being the least expensive, it will be necessary to favor refills at home.
