This is the result of four years of work by a team of 25 people, engineers and researchers from CNRS, Stellantis and Saft: IBIS (By Intelligent integrated battery systemor Integrated Intelligent Battery System) is an innovative prototype battery for energy storage that should be more efficient, more reliable and less expensive to improve the range of electric vehicles while taking up less space on board.

“Our path to electrification is based on innovation and research excellence that uses the latest technologies to meet the real needs of our EV customers, such as range, capacity and affordability, while reducing our carbon footprint through increased efficiency.”Ned Couric, chief engineering and technology officer of Stellantis, said on the occasion: “This revolutionary battery system could mark a milestone in Stellantis’ commitment to providing useful, simple and advanced technology for everyone. »

Electric cars: a revolutionary smart battery

The IBIS project has been the subject of numerous patents and is a a true innovation in electrical energy conversion systems with many new technical concepts that allow both automotive and stationary applications.

there Smart battery IBIS integrates electronic conversion boards that act as a power inverter and charger directly into the lithium-ion battery module: this frees up space in the vehicle while reducing costs. A sophisticated control system produces alternating current to power the electric motor directly from the battery.

Now the partners of the IBIS project are working on production of an electric car prototype, which will soon be tested at Stellantis on test tracks as well as on open roads. This technology should see the light of day on production cars of Stellantis brands by the end of this decade.

Electric cars: efficient and profitable technology

With this new efficient and profitable technology, IBIS makes it possible reduce weight and cost motorization, but also the production of electric cars with many new functions.

In addition to automotive applications, this battery can also be used for stationary energy storage for electrical networks and renewable energy sources. It is Saft, the project partner, who will make sure to offer turnkey installations that are easy to maintain, more energy efficient and with a lower carbon footprint.

These two uses, automotive and stationary storage, will make the technology more affordable and competitive through volume effects in various emerging markets. Thus, it will allow Stellantis to democratize access to the electric car while increasing its efficiency.
