The management of recharging, a creator of value for ecosystem players
The 2019 Enedis report indicated that the integration of the electric vehicle into the French electricity system would be done without significant difficulty, at both local and national level.
This new report sheds light on the management of electric vehicle charging. Piloting offers savings opportunities to the “consumer” of up to 90 € / year per electric vehicle, and, in the medium term, piloting recharging will also make it possible to participate in the proper integration of the electric vehicle into the within the distribution network.
For “the consumer”, recharging an electric vehicle will make it possible to achieve significant savings by intervening when electricity is cheapest; by moderating the subscribed power and that of the connection;
For the community, load control will limit the cumulative power demanded from the network by electric vehicles, and consequently could allow optimization of network infrastructure investment needs;
For the electricity system as a whole, the management of recharging will make it possible to promote local and / or green supply, in particular by synchronizing the recharging of electric vehicle batteries with the production of renewable energy. This management will thus promote self-consumption and new uses of electricity.
The electric vehicle experienced sustained growth in the first half of 2020, with nearly 70 units sold in France, or twice as many as over the same period in 000, despite the health crisis. There are currently nearly 2019 charging stations open to the public, directly or indirectly connected to the public distribution network.
Ultimately, new local flexibilities
Managing the recharging of a significant number of electric vehicles can also help achieve “local flexibility”. This control method aims to appropriately distribute these new incoming and outgoing energy flows to the electricity distribution network, by modifying the recharge demand, or even by reinjecting the electricity stored in the batteries. The use of these flexibilities could take all its value in areas where the network would be subject to constraints in terms of availability, these areas being few at present.
Enedis, a key player in electric mobility
As operator of the public electricity distribution network on 95% of French territory, Enedis plays a key role in the deployment of recharging infrastructures by ensuring their connection, their continuous supply as well as the metering of the energy distributed. Enedis is also a player in electric mobility as a user: with more than 3 electric vehicles, the company has the 000nd largest fleet of electric vehicles in France. Finally, Enedis resolutely supports innovation in electric mobility, as evidenced by projects in the field, and studies already carried out by the company and its partners on the integration of electric vehicles into the network and on the evolution of behavior. . To do this, Enedis carries out, within a laboratory created in 2, charging control tests for its own internal fleet and contributes to the development of intelligent charging control solutions within the framework of the various demonstrators in Classes.
In line with the work undertaken by Enedis for several years, the report on the role of charging management for the development of electric vehicles and its interaction with the distribution network aims to shed light on the contributions of this management, in terms of solutions, value and coordination of actors. It is fully in line with Enedis' desire to support the development of electric mobility.
