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 features straight into the battery pack. The car represents the primary cellular utility of know-how developed by a French collaborative analysis undertaking 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 purposes, supplying energy on to the motor whereas concurrently offering electrical energy to the car’s 12V community and auxiliary methods.
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 typical battery configurations of the identical dimension. The know-how additionally reduces car 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 reasonably priced EVs to our prospects.”
Preliminary charging exams present 15% discount in charging instances, with AC charging on a 7 kW charger lowering from seven to 6 hours, together with 10% vitality financial savings through the charging course of. The built-in design additionally simplifies upkeep procedures and enhances potential for second-life battery purposes in stationary vitality 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 strong testomony to Saft’s innovation management,” stated Hervé Amossé, EVP Vitality Storage Programs at Saft. “By embedding IBIS know-how into our next-generation purposes, we’re unlocking a brand new period of clever, versatile, and sustainable vitality options.”
Part 2 of the undertaking launched in June 2025 with continued French Authorities help by the France 2030 program. Present testing focuses on consultant driving situations to guage the know-how’s efficiency for potential integration into Stellantis manufacturing autos by decade’s finish.
Past automotive purposes, the businesses point out IBIS structure may lengthen to rail, aerospace, marine, and information heart purposes, suggesting broader industrial potential for the built-in vitality storage strategy.
