Stellantis, in partnership with Saft (a TotalEnergies subsidiary), has unveiled a groundbreaking prototype vehicle featuring IBIS technology— a French-based collaborative research project aimed at developing a more efficient, sustainable, and cost-effective energy storage and electric conversion system. With real-world road testing now underway, this milestone marks a major leap forward in advancing electrification for both mobile and stationary energy applications.
The first fully functional IBIS-equipped battery electric vehicle (BEV) is a new Peugeot E-3008, built on the STLA Medium platform. This prototype follows years of design, modeling, and simulation by Stellantis and Saft, with support from E2-CAD, Sherpa Engineering, and leading French research institutions, including CNRS, Université Paris-Saclay, and Institut Lafayette.
Since mid-2022, an initial IBIS demonstrator for stationary applications has been operational, validating key technical concepts and generating numerous patents. The transition to a mobile prototype represents a leap forward in the system’s development.
IBIS reimagines the electric powertrain by embedding inverter and charger functionalities directly into the battery, regardless of chemistry or application. This architecture supports both alternating current (AC) and direct current (DC), supplying electric energy directly to the motor or grid, while simultaneously supplying the vehicle’s 12V network and auxiliary systems.
