Kallista Energy to deploy 80 high-power electric charging stations on French highways by 2024

Kallista Energy va déployer 80 stations de recharge électrique à forte puissance sur les autoroutes de France d’ici 2024 Cybersecurity

Energy producer Kallista Energy announced on July 2 that it plans to deploy 80 electric vehicle charging stations across France by 2024, along highways and major highways. A first pilot station should be installed in 2021. “The network that we are considering covers the entire territory with approximately one terminal every 150 kilometers (km), says Johann Tardy, CEO of Kallista Energy. With between eight and forty-eight charging points per station, this is extremely ambitious compared to what exists today. “

At present, the French network of charging stations for electric vehicles on motorways is essentially limited to three networks. “Concretely, we need more terminals today”, admits Mr. Tardy. Initially made up of 217 terminals, the Corri-door network of Izivia, a subsidiary of EDF, lost 189 at the start of the year after a security problem. Tesla’s network is made up of several dozen stations. “It is properly meshed, works very well and we are inspired by it, says Mr. Tardy. The problem is that it’s only open to Tesla. “ Finally, a consortium of car manufacturers is behind the Ionity network, which is developing across the “European corridors”.

Power between 50 kW and 350 kW

With powers ranging from 50 kilowatts (kW) to 350 kW, the stations in the Kallista Energy network will be E-charger 600 models supplied by the wind turbine manufacturer Enercon. “They have installed few, specifies Mr. Tardy. The first commercial station was in late 2019. ” They are made up of two 300 kW power converters behind which the power is distributed over the different charging points. “The converters they use are the same as those in their wind turbines, specifies Mr. Tardy. It is a reliable and proven technology for over two decades. “

If a power of 350 kW makes it possible to envisage an ultra-fast recharging, no vehicle supports it today, indicates Mr. Tardy: “Except for high-end electric vehicles and Tesla, the batteries are recharged today with powers between 50 kW and 100 kW. But battery manufacturers tell us that technologies capable of accepting powers of 350 kW will arrive quickly. However, our stations are designed to operate at least 15 years and must not become obsolete. “ He cites for example “all-solid” batteries, cooled by a dielectric liquid, or sodium-ion technology like that of Tiamat.

Stations directly connected to wind turbines

The deployment of charging stations will be done in parallel with that of mini wind farms. The 20 that Kallista Energy owns are not necessarily located in ideal locations, each station will be connected to two wind turbines built nearby and connected to the grid, where the surplus electricity produced will be sent. This allows to optimize the network and share the costs of a connection, justifies Mr. Tardy: “The cost of recharging is based on the price of the station infrastructure only, without that of the connection. “

The target price envisaged is 0.30 euros per kilowatt hour (€ / kWh), or a full estimated at € 15 for recharging a 50 kWh battery of the Peugeot e-208 or Renault Zoe type, says Kallista Energy. A price approximately twice lower than that observed by Mr. Tardy and his collaborators at the charging stations today: between 27 € and 39 €.
