Auto giant Stellantis unveils revolutionary battery system unlocking new EV era

Stellantis has taken a bold step toward redefining the future of electric vehicles (EVs) with the unveiling of its Intelligent Battery Integrated System (IBIS).

Developed in partnership with Saft, a subsidiary of TotalEnergies, the breakthrough technology eliminates the need for separate inverters and chargers, which are traditionally responsible for converting and managing electric power.

The result is a simpler, more efficient, and more compact energy system that could transform the way EVs are designed and built.

With real-world testing already underway in France, this innovation could soon reshape both electric mobility and stationary energy applications.

Improves power output and cuts charging times

At its core, IBIS reimagines the EV powertrain.

Instead of using bulky, standalone components, the system integrates key electronic, like the inverter and charger, directly into the battery pack itself.

This not only streamlines design and assembly but also boosts energy efficiency by up to 10 percent, improves power output by 15 percent, and cuts charging times by around 15 percent.

The first working prototype to feature IBIS is a Peugeot E-3008, built on Stellantis’ STLA Medium platform, now undergoing on-road testing.

The benefits extend far beyond performance metrics.

IBIS reduces overall vehicle weight by roughly 40 kilograms (88lbs) and frees up to 17 liters of space, giving designers more room to improve aerodynamics and cabin space.

Maintenance becomes simpler, too, since there are fewer components to service.

And when a battery reaches the end of its automotive life, the integrated system makes it easier to repurpose for stationary energy storage, further enhancing sustainability.

Stellantis aims to integrate the new technology by 2030

Saft’s Executive VP of Energy Storage Systems Hervé Amossé said that IBIS ‘unlocks a new era of intelligent, flexible, and sustainable energy solutions,’ emphasizing that its potential beyond cars.

Backed by the French government’s France 2030 initiative, Phase 2 of the IBIS project focuses on extensive road testing and further development.

If successful, Stellantis aims to integrate the technology into production vehicles before the end of the decade.

However, Stellantis isn’t alone in terms of developing new battery technology for EVs.

Huawei recently created a patent for a battery that offers nearly 2,000 miles of driving range and 5-minute charging times, which will be a game-changer in the future.

And Porsche has already made wireless charging for its cars a reality, starting with the Cayenne EV.

With heavy competition within the industry, it remains to be seen how much IBIS can shake up the EV market.
