Stellantis has begun real-world highway testing of a prototype Peugeot E-3008 geared up with an Clever Battery Built-in System (IBIS), which embeds inverter and charger features instantly into the battery pack. The car represents the primary cell utility of know-how developed by way of a French collaborative analysis challenge between Stellantis and Saft, a TotalEnergies subsidiary.
The IBIS system reimagines electrical powertrain structure by integrating energy electronics elements which might be historically separate from the battery. This configuration helps each alternating and direct present purposes, supplying energy on to the motor whereas concurrently offering electrical energy to the car’s 12V community and auxiliary programs.
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 standard battery configurations of the identical measurement. The know-how additionally reduces car weight by roughly 40 kilograms and frees as much as 17 liters of inside area.
“This challenge 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 cheaper. These are the sorts of improvements that assist us ship higher, extra inexpensive EVs to our clients.”
Preliminary charging exams present 15% discount in charging instances, with AC charging on a 7 kW charger reducing from seven to 6 hours, together with 10% power financial savings throughout the charging course of. The built-in design additionally simplifies upkeep procedures and enhances potential for second-life battery purposes in stationary power storage.
The prototype follows improvement work that started in mid-2022 with a stationary IBIS demonstrator, which validated core technical ideas and generated a number of patents. The cell 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 challenge is a robust testomony to Saft’s innovation management,” stated Hervé Amossé, EVP Vitality Storage Methods at Saft. “By embedding IBIS know-how into our next-generation purposes, we’re unlocking a brand new period of clever, versatile, and sustainable power options.”
Part 2 of the challenge launched in June 2025 with continued French Authorities help by way of the France 2030 program. Present testing focuses on consultant driving circumstances to guage the know-how’s efficiency for potential integration into Stellantis manufacturing automobiles by decade’s finish.
Past automotive purposes, the businesses point out IBIS structure may prolong to rail, aerospace, marine, and information heart purposes, suggesting broader business potential for the built-in power storage strategy.
