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 capabilities straight into the battery pack. The automobile represents the primary cell utility of expertise developed by means of a French collaborative analysis mission between Stellantis and Saft, a TotalEnergies subsidiary.
The IBIS system reimagines electrical powertrain structure by integrating energy electronics elements 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 vitality 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 expertise additionally reduces automobile weight by roughly 40 kilograms and frees as much as 17 liters of inside area.
“This mission displays our perception that simplification is innovation,” mentioned 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 clients.”
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% vitality financial savings throughout the charging course of. The built-in design additionally simplifies upkeep procedures and enhances potential for second-life battery functions in stationary vitality 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 mission is a robust testomony to Saft’s innovation management,” mentioned Hervé Amossé, EVP Vitality Storage Techniques at Saft. “By embedding IBIS expertise into our next-generation functions, we’re unlocking a brand new period of clever, versatile, and sustainable vitality options.”
Part 2 of the mission launched in June 2025 with continued French Authorities help by means of the France 2030 program. Present testing focuses on consultant driving situations to judge the expertise’s efficiency for potential integration into Stellantis manufacturing autos by decade’s finish.
Past automotive functions, the businesses point out IBIS structure might prolong to rail, aerospace, marine, and information heart functions, suggesting broader business potential for the built-in vitality storage strategy.
