Stellantis Launches Road Tests for Peugeot E-3008 with IBIS Technology

Stellantis and Saft begin real-world tests of Peugeot E-3008 with IBIS, a battery system integrating inverter and charger, boosting efficiency and reducing weight.

Stellantis and Saft have taken a major step forward in electric mobility by unveiling the first prototype vehicle equipped with the Intelligent Battery Integrated System (IBIS). Developed in collaboration with CNRS, Université Paris-Saclay, and Institut Lafayette, IBIS embeds the inverter and onboard charger directly into the battery pack. This innovation reduces vehicle weight by around 40 kg, frees up to 17 liters of space, and delivers a 15% power boost with the same battery size.

The prototype is based on the STLA Medium platform and debuts on the new Peugeot E-3008. After proving its concept in stationary applications since mid-2022, IBIS has now entered real-world road testing. Early data shows about a 10% efficiency gain and a 15% reduction in charging time — for example, cutting 7 kW AC charging sessions from seven to six hours.

One of IBIS’s strengths is its versatility: the architecture supports different battery chemistries and handles both AC and DC power flows. Integrating these functions simplifies maintenance, allows safe access to the battery for module replacement, and paves the way for easier second-life use in stationary energy systems.

Stellantis highlights that the project is backed by France’s France 2030 program and is entering Phase 2, focusing on intensive road tests. If successful, IBIS could be integrated into Stellantis production vehicles before the end of the decade.

Industry observers note that embedding power electronics into the battery is an emerging trend. Porsche, for instance, is exploring modular three-phase inverter concepts but has not announced production timelines. This gives Stellantis an opportunity to become one of the first automakers to bring such a system from lab to road.

The potential for IBIS goes beyond automotive applications. Its scalable architecture could serve rail, aerospace, marine, and data center projects, though no specific pilots have been disclosed yet.

With the Peugeot E-3008 prototype now on the road, attention turns to testing results that will determine whether this breakthrough is ready for mass production — and whether it can set a new standard for compact, efficient, and flexible electric powertrains.
