Choose when to charge your vehicle to reduce its environmental impact and lower your bill
"Today, we need to develop high-power charging stations that can quickly recharge a vehicle. For example, in 20 minutes, our research project makes it possible to recover 300 km of range!" explains Daniel Marin, research engineer at L2EP.
Based on this observation, Daniel Marin and Thomas Roillet, research engineers at L2EP, studied the B2RI (Intelligent Fast Charging Station), the technical, economic, and environmental impacts of fast charging on building energy consumption, together with their partner, the DBT group, which specializes in the design, manufacture, and marketing of electric vehicle charging stations. This project was supported by the Hauts-de-France region.
To this end, a full-scale demonstrator with a nominal electrical power of 150 kW was installed in February 2020 on the Arts et Métiers campus Arts et Métiers Lille. It enables DBT to characterize the behavior of these high-power terminals and optimize their use. The applications are straightforward, as they enable real-world testing of fast charging for electric vehicles in relation to building consumption.
We have created a database of actual vehicle charging data to improve our models in relation to the characteristics of the electrical grid.
A research project that has now come to an end, modeling rapid charging in relation to buildings and associated scenarios, was finalized in early 2021 and the results were presented to partners during a webinar. The proposed scenarios thus make it possible to choose when to fast charge your vehicle in order to pursue two objectives: reducing your bill or reducing your environmental impact by coupling with local renewable energy production.
Electric mobility and collective self-consumption in social housing to promote energy efficiency
Together with its partners, Partenord Habitat,EDF, Enedis,ADEME, the Hauts-de-France Region, and the ERDF fund, Arts et Métiers combining new uses of the Energy Transition: lectric mobility, and collective self-consumption (ACC) in social housing.
To this end, a smart energy management demonstrator combining collective self-consumption via photovoltaic panels and car sharing of an electric vehicle connected to a bidirectional charging station will be made available to tenants of Partenord Habitat social housing in Lille (Ilot Saint-So residence, in the Porte de Valenciennes district of Lille).
For this first in France, presented on June 16, theArts et Métiers teamsArts et Métiers "vehicle-to-grid" technology: the vehicle is charged with energy produced locally by photovoltaic panels, but can also, thanks to the bidirectional charging station, contribute to powering the building with the energy stored in its battery.
Dynamic energy modeling will enable comparison of optimization scenarios for Partenord Habitat's full-scale demonstrator.
"This innovation was made possible thanks to the expertise of the L2EP laboratory in building 'digital twins' that represent the actual behavior of these systems as they interact with their users,"explain Thomas Roillet and Daniel Marin. Beyond its appeal for residential use, this technology has the advantage of contributing to the smooth operation of larger-scale electrical distribution networks. To supplement its renewable charge during the day, the vehicle can also charge at night when domestic demand is lower, thereby helping to reduce consumption during peak periods. The aim of this experiment is to combat polluting emissions by reducing the number of cars in cities and to support the national electricity production network by producing its own energy.
The Lille-basedArts et Métiers teamsArts et Métiers expand their research work at the European level in order to develop new innovations related to electric vehicle charging .
