World premiere: the first vehicle prototype equipped with a battery without a charger and inverter
CentraleSupélec hosted a world first: the presentation of a prototype of a Peugeot E-3008 vehicle equipped with a new battery concept born from French partnership research.
This is the IBIS (Intelligent Battery Integrated System) research project, which proposes a new type of battery that required the filing of more than 30 patents.
This battery not only offers significantly reduced weight and cost, but also increased performance and longevity. This project fully embodies CentraleSupélec's commitment to the energy transition and energy sovereignty.
- The IBIS system eliminates the need for a charger and inverter, improving vehicle space utilization and simplifying maintenance.
- This innovative development marks a significant step forward for mobile and stationary energy applications
- The IBIS project is a collaborative research initiative in France that aims to create a more efficient, sustainable and cost-effective energy storage and electrical conversion solution.
IBIS reimagines the electric powertrain by integrating inverter and charger functions directly into the battery, regardless of its chemistry or application. This architecture supports both alternating current (AC) and direct current (DC), allowing direct charging of the engine or the grid, while simultaneously powering the vehicle's 12V network and auxiliary systems.
Key Benefits
- Efficiency and performance: Up to 10% improvement in energy efficiency (WLTC cycle) and 15% power gain (172 kW vs. 150 kW) with the same battery size.
- Weight and space savings: Reduces vehicle weight by approximately 40 kg and frees up to 17 liters of volume, improving aerodynamics and design flexibility.
- Faster charging: Initial results show a 15% reduction in charging time (e.g., from 7 to 6 hours on a 7 kW AC charger), as well as 10% energy savings.
- Simplified maintenance: Facilitates maintenance and increases the possibilities of reusing batteries for second life in automotive and stationary applications.
IBIS also streamlines maintenance and facilitates the reuse of second-life batteries in stationary automotive applications by reducing the need for extensive reconditioning.
Le GeePs - Electrical and Electronic Engineering Laboratory of Paris, CNRS joint unit – CentraleSupelec - Paris-Saclay University - Sorbonne University, is one of the academic actors involved in the IBIS project from the start in 2015.
The IBIS project was funded by the France 2030 Investment Plan, administered by theADEME and coordinated by Stellantis et Saft.
