Integrating Inverter and Charger Functions in Energy Storage Battery Prototype
After four years of design, modeling, and simulation, a team of 25 people comprising CNRS (French National Centre for Scientific Research), Stellantis, and Saft engineers and researchers unveiled an innovative prototype of an energy storage battery that integrates the inverter and charger functions. This breakthrough development aims to enhance the efficiency, reliability, and cost-effectiveness of battery-electric vehicles while also creating more space within the vehicle.
The Intelligent Battery Integrated System (IBIS) Project
The collaborative research project, known as the Intelligent Battery Integrated System (IBIS), has been a joint effort between CNRS, Stellantis, and Saft. The project, which has been operational since summer 2022, has involved extensive design and simulation work and has resulted in numerous patents. It represents a significant departure from existing electrical energy conversion systems and has successfully validated various new technical concepts for future automotive or stationary applications.
Advancements in Electromobility
The IBIS project is set to revolutionize the design of electric powertrains in the field of electromobility. By integrating the electronic conversion boards responsible for power inversion and charging functions as close as possible to the lithium-ion battery cells, the project enables the direct production of alternating current for electric motors. This innovative approach enhances the efficiency and range of battery-electric vehicles.
Future Plans and Goals
The IBIS project partners are now focused on building a fully functional prototype vehicle that will undergo testing on Stellantis development benches, test tracks, and open roads. The team aims to make this technology available on Stellantis brand vehicles before the end of the decade. By developing an efficient and cost-competitive technology, the IBIS project aims to reduce vehicle weight and the cost of EV powertrain and vehicle manufacturing while introducing a range of new features.
Benefits for Stationary Energy Storage and Renewable Energy Integration
In addition to its impact on electromobility, the IBIS project also offers significant benefits for stationary energy storage and renewable energy integration. Project partner Saft will be able to provide turnkey installations with improved battery availability, optimized energy utilization, and a smaller physical footprint. The unique architecture of the IBIS battery simplifies maintenance and upgrades while reducing the carbon footprint of the facility. The combination of battery solutions for electric vehicles and stationary storage enhances the competitiveness of both offerings, leveraging volume effects in growing markets.
Funding and Partnerships
The IBIS project is funded by the Future Investment Plan, administered by ADEME (the Environment and Energy Management Agency), and coordinated by Stellantis. It brings together industrial partners Saft (TotalEnergies Group), E2CAD, and Sherpa Engineering, as well as CNRS research laboratories (GeePs, SATIE, LEPMI) and Institut Lafayette.
