Stellantis has begun real-world street testing of a prototype Peugeot E-3008 outfitted with an Clever Battery Built-in System (IBIS), which embeds inverter and charger capabilities straight into the battery pack. The automobile represents the primary cellular software of know-how developed by way of a French collaborative analysis undertaking between Stellantis and Saft, a TotalEnergies subsidiary.
The IBIS system reimagines electrical powertrain structure by integrating energy electronics parts which can be historically separate from the battery. This configuration helps each alternating and direct present functions, supplying energy on to the motor whereas concurrently offering electrical energy to the automobile’s 12V community and auxiliary techniques.
Testing outcomes point out the built-in system delivers as much as 10% enchancment in power effectivity throughout WLTC cycle testing and 15% elevated energy output, producing 172 kW in comparison with 150 kW with typical battery configurations of the identical dimension. The know-how additionally reduces automobile weight by roughly 40 kilograms and frees as much as 17 liters of inside area.
“This undertaking displays our perception that simplification is innovation,” stated Ned Curic, Chief Engineering and Know-how Officer at Stellantis. “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.”
Preliminary charging assessments present 15% discount in charging occasions, with AC charging on a 7 kW charger lowering from seven to 6 hours, together with 10% power financial savings in the course of the charging course of. The built-in design additionally simplifies upkeep procedures and enhances potential for second-life battery functions in stationary power storage.
The prototype follows growth work that started in mid-2022 with a stationary IBIS demonstrator, which validated core technical ideas and generated a number of patents. The cellular prototype was developed with help from E2-CAD, Sherpa Engineering, and French analysis establishments together with CNRS, Université Paris-Saclay, and Institut Lafayette.
“The IBIS undertaking is a robust testomony to Saft’s innovation management,” stated Hervé Amossé, EVP Vitality Storage Programs at Saft. “By embedding IBIS know-how into our next-generation functions, we’re unlocking a brand new period of clever, versatile, and sustainable power options.”
Section 2 of the undertaking launched in June 2025 with continued French Authorities help by way of the France 2030 program. Present testing focuses on consultant driving situations to judge the know-how’s efficiency for potential integration into Stellantis manufacturing autos by decade’s finish.
Past automotive functions, the businesses point out IBIS structure might lengthen to rail, aerospace, marine, and knowledge middle functions, suggesting broader business potential for the built-in power storage method.
