The Clever Battery Built-in System (IBIS) improves car area utilization and simplified upkeep by eliminating the necessity for separate charger and inverter elements
Stellantis, in partnership with Saft (a TotalEnergies subsidiary), has unveiled a groundbreaking prototype car that includes IBIS expertise— a French-based collaborative analysis undertaking geared toward creating a extra environment friendly, sustainable, and cost-effective power storage and electrical conversion system. With real-world highway testing now underway, this milestone marks a serious leap ahead in advancing electrification for each cellular and stationary power functions.
A brand new period in electrical powertrain design
The primary totally purposeful IBIS-equipped battery electrical car (BEV) is a brand new Peugeot E-3008, constructed on the STLA Medium platform. This prototype follows years of design, modeling, and simulation by Stellantis and Saft, with help from E2-CAD, Sherpa Engineering, and main French analysis establishments, together with CNRS, Université Paris-Saclay, and Institut Lafayette.
Since mid-2022, an preliminary IBIS demonstrator for stationary functions has been operational, validating key technical ideas and producing quite a few patents. The transition to a cellular prototype represents a leap ahead within the system’s growth.
The way it works: Integration that simplifies all the things
IBIS reimagines the electrical powertrain by embedding inverter and charger functionalities immediately into the battery, no matter chemistry or utility. This structure helps each alternating present (AC) and direct present (DC), supplying electrical power on to the motor or grid, whereas concurrently supplying the car’s 12V community and auxiliary programs.
Key Advantages
- Effectivity & Efficiency: As much as 10% power effectivity enchancment (WLTC cycle) and 15% energy acquire (172 kW vs. 150 kW) with the identical battery dimension.
- Weight & Area Financial savings: Reduces car weight by ~40 kg and frees as much as 17 liters of quantity, enabling higher aerodynamics and design flexibility.
- Sooner Charging: Early outcomes present a 15% discount in charging time (e.g., from 7 to six hours on a 7 kW AC charger), together with 10% power financial savings.
- Simplified Upkeep: Simpler servicing and enhanced potential for second-life battery reuse in each automotive and stationary functions.
IBIS additionally streamlines upkeep and facilitates the reuse of second-life batteries in stationary automotive functions by lowering the necessity for intensive reconditioning.
Management views
Ned Curic, Chief Engineering and Expertise Officer at Stellantis:
“This undertaking displays our perception that simplification is innovation. By rethinking and simplifying the electrical powertrain structure, we’re making it lighter, extra environment friendly, and less expensive. These are the sorts of improvements that assist us ship higher, extra inexpensive EVs to our prospects.”
Hervé Amossé, EVP Vitality Storage Programs at Saft:
“The IBIS undertaking is a strong testomony to Saft’s innovation management. By embedding IBIS expertise into our next-generation functions, we’re unlocking a brand new period of clever, versatile, and sustainable power options. Saft continues to prepared the ground in superior analysis, providing long-term, cost-effective options tailor-made to evolving market wants.”
What’s Subsequent: Part 2 of the undertaking started in June 2025 with continued help from the French Authorities by France 2030. The main target now shifts to real-world testing below consultant driving situations, which may pave the way in which for the combination of IBIS expertise into Stellantis manufacturing autos by the top of the last decade.
Past automotive, the IBIS structure holds promise for a variety of functions, together with rail, aerospace, marine, and information facilities—underscoring Stellantis and Saft’s dedication to scalable, sustainable electrification.
