Integrated EV Battery Technology Begins Road Testing in France

The French National Center for Scientific Research (CNRS) recently announced that a pure electric vehicle equipped with the Intelligent Battery Integrated System (IBIS) has begun real-world road testing. This system helps improve vehicle space utilization and simplifies maintenance processes.

According to the announcement, this electric vehicle model is the Peugeot E-3008, jointly launched by multinational automaker Stellantis and French battery company Saft. The integrated IBIS restructures the electric powertrain by directly incorporating the functions of the inverter and charger into the battery itself, and it is not limited by the battery's chemical composition or application scenario. This architecture supports both alternating current (AC) and direct current (DC), can directly power the motor or the grid, and simultaneously supplies energy to the vehicle's 12V network and auxiliary systems.

The IBIS project is a collaborative research initiative involving institutions like the CNRS, aiming to create more efficient, sustainable, and economical energy storage and power conversion solutions. The developed IBIS offers several advantages: with the same battery size, it can achieve up to a 10% improvement in energy efficiency and a 15% power gain; the overall vehicle weight can be reduced by approximately 40 kg, freeing up to 17 liters of space; initial tests indicate charging time can be shortened by 15% while saving 10% energy; maintenance is simpler, and it can facilitate the reuse of retired batteries.

The announcement stated that the current focus is testing the E-3008 under real road conditions to lay the foundation for mass production of models equipped with IBIS. Furthermore, IBIS is expected to have broad application prospects in fields such as rail transportation, aerospace, maritime transport, and data centers.
