Key Takeaways
1. Innovative Design: The IBIS battery system delivers alternating current directly, eliminating the need for separate inverters, onboard chargers, or DC converters.
2. Efficiency Gains: The system saves 17 liters of space, reduces weight by 88 lbs, charges 15% faster, and decreases WLTP consumption and energy losses by 10%.
3. Simplified Construction: IBIS streamlines vehicle design compared to standard lithium-ion batteries, which require additional charging systems.
4. Versatile Applications: The IBIS framework is adaptable, with potential uses for rail transport, aerospace, maritime shipping, and data centers.
5. Future Integration: Stellantis plans to integrate IBIS into production vehicles by 2029 or 2030, aiming for lighter and more efficient electric vehicles.
IBIS has been in development for more than six years, working alongside Saft, a battery expert that is part of TotalEnergies. As reported by InsideEVs, this system delivers alternating current straight at the output, which means separate inverters, onboard chargers, or DC converters are no longer necessary. The current prototype is built upon the Peugeot E-3008 and is currently undergoing tests on public roads.
Efficiency and Space Saving
Stellantis highlights several benefits of the battery system. It saves around 17 liters of space and reduces weight by nearly 88 lbs. Charging with AC becomes 15% quicker, and both WLTP consumption and energy losses are decreased by 10%. Meanwhile, battery power can increase by as much as 15%, reaching 172 kW without changing the size. Maintenance is made easier, and the battery can also be used for second-life applications.
Simplifying Vehicle Design
Unlike standard lithium-ion batteries that store direct current and need extra inverters, IBIS greatly streamlines the vehicle’s construction. Companies like Tesla and Volkswagen still rely on separate charging systems. With its compact design, reduced weight, and improved energy efficiency, IBIS offers distinct advantages.
Future Potential
The IBIS framework is quite adaptable as well. A stationary version has been in testing since 2022, and it could potentially be utilized for rail transport, aerospace, maritime shipping, or data centers in the future.
Stellantis’ battery initiative includes a team of 25 engineers from Saft, CNRS, the Sorbonne, the University of Paris-Saclay, and the Lafayette Institute. Stellantis aims to integrate IBIS into production vehicles by 2029 or 2030. This technology could pave the way for lighter, more efficient, and easier-to-maintain electric vehicles.
