Increase in the price of Superchargers: cheaper to drive on diesel than on electric?

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

Currently, thanks to the tariff screen applied by the government, the price of electricity for individuals has “only” increased by 4% in 2022 and may increase by 15% in 2023. In the wholesale market, the price per MWh increased. from €85 in 2021 to €1,000 in September 2022. A stratospheric price increase affecting energy distributors.

40% increase

Thus, Allego, specialist in terminals for electric cars, 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 an increase in October . For a quick 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. This is an increase of €0.14. After 7 October, the rates drop to €0.88 per kWh on a power terminal below 50 kW and €0.98 per kWh on terminals over 50 kW.

On the Tesla site, 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 at €0.67 throughout France, while the charge for vehicles from other manufacturers is now €0.79. Currently, the Ionity price without subscription remains at €0.69 and €0.39 with the monthly subscription at €17.99.

Between the purchase price on average higher than their thermal equivalent, a decrease in the ecological bonus which will be reduced in 2023 and an increase in the price of fast charging, motorists’ wallets risk being hit quite hard. In addition, after a quick calculation, it should be noted that a motorway trip in an electric car can end up costing more than the same trip with a diesel thermomobile.

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 trip on e.g. 650km, the total cost of travel with the Citroën C5 Aircross will be €39.65x €1.75 = €69.38, applying the government’s 30ct 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 fromAutomotive Magazine is 19kWh/100km. We have also chosen a Kia Niro EV, whose consumption on the motorway is 23.2 kWh/100 km (measured by us).

The results of our calculations are quite interesting. If we take 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 price of €60.58. On the other hand, with the same vehicle, travel costs rise 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 charge at home and then a recharge on the Ionity network including the subscription, the amount rises to €64.97. On the other hand, the price 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 trip. Even worse, it will take €119.13 if you only charge on Supercharger’s network; which of course would be nonsense, but the math at least allows it to be brought to light.

Results must be put into perspective of use

These results should be interpreted with caution, as the first charging of the electric car will take place in the vast majority of cases at home, where the amount per kWh is currently €0.17. Finally, and as we emphasize through our tests, the highway trip is the least favorable for 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 you rush to buy a vehicle, we advise you to think about what use you will have for it and how you will be led to recharge it; Since slow recharges are the cheapest, it will be necessary to prefer top-ups at home.
