Expectations by 2030, including Stellantis's battery ecosystem.
Different battery chemistries to enhance flexibility.

Stellantis and Infineon Technologies will work jointly on the power architecture for Stellantis’s electric vehicles. To support this, the companies signed supply and capacity agreements that will serve as the foundation for the planned collaboration to develop the next generation of power architecture, including:

Infineon’s PROFET smart power switches, which will replace traditional fuses, reduce wiring, and enable Stellantis to become one of the first automakers to implement intelligent power network management.
Silicon-carbide (SiC) semiconductors, which will support Stellantis in its efforts to standardize its power modules, improve the performance and efficiency of electric vehicles while also reducing costs.
AURIX microcontrollers, which target the first generation of the STLA Brain zonal architecture.

Stellantis and Infineon signed supply and capacity agreements for PROFET power switches and silicon-carbide CoolSiC semiconductors.

Stellantis and Infineon are also in the process of extending their cooperation with the implementation of a Joint Power Lab. The Lab will define the next-generation scalable and intelligent power architecture enabling Stellantis software-defined vehicles.

“As outlined in our strategic plan, Dare Forward 2030, we are securing the supply of crucial semiconductor solutions required to continue our transition to an electrified future, leveraging innovative E/E architectures for our next-generation platforms,” said Maxime Picat, Stellantis Chief Purchasing and Supplier Quality Officer.

2030 Goals for BEVs: Sales and New Launches

By 2030, Stellantis plans to offer more than 75 full-electric models representing 5 million units in annual battery electric vehicle (BEV) sales globally.

Specifically, the company is setting the course for 100% of passenger car sales in Europe and 50% of passenger car and light-duty truck sales in the United States to be BEVs by the end of the decade. For all brands, new product launches in Europe will be BEV only from 2026 onward. And Stellantis plans to offer no fewer than 25 all-new BEV products in the United States by 2030.

To meet these electric-vehicle targets, Stellantis is continuing to strengthen its battery ecosystem. It will be supported by five gigafactories (three in Europe and two in North America) that will contribute to its estimated need of at least 400 GWh of capacity by 2030.

In addition, the company is accelerating development of solid-state batteries that will give products more range, as well as being faster charging and lighter. The company is also working to secure a decarbonized supply of battery-grade lithium hydroxide (agreements are already in place to support North American and European operations) and build a fast-charging network in Europe.

Electric-Drive Modules, Multi-Energy Platforms, Cell Chemistries

Stellantis knows that range, charging time, affordability, and choice are of prime importance to customers. The company’s plan calls for serving a wide variety of vehicle segments and ranges with a combination of four state-of-the-art BEV-native multi-energy vehicle platforms—STLA Small, Medium, Large, and Frame—in addition to three electric-drive modules (EDMs) to provide modularity and performance, as well as different battery cell chemistries to ensure affordability.

These combinations will offer driving ranges of between 500-800 kilometers/300-500 miles and front-, rear- and all-wheel-drive propulsion. Each platform will be capable of supporting production of up to two million units per year

This third-generation technology is highly flexible, with a design that’s both modular and scalable (from 70 to 330 kW), and it has a high level of commonality to optimize overall cost efficiency. A key element of this strategy is the development of one power inverter for all three EDM families with scalable technology, a common microprocessor, and in-house controls and software.

The STLA Medium platform appears on the new Peugeot E-3008 equipped with the long-range version BEV propulsion system. Recently, the vehicle traveled from Paris to Nice (France), covering nearly 1,000 km at highway speeds with just two charging stops.

Chemistries with Different Densities

Stellantis’s current dual-chemistry battery approach includes nickel- and cobalt-free as well as nickel-based alternatives, offering a range of energy densities. The company extended its range with a lithium-iron-phosphate (LFP) battery pack that offers a cost-efficient and more affordable option for BEV models.

In addition, Stellantis is exploring innovative battery cell and pack technologies, such as solid state, sodium-ion, lithium-sulfur, and IBIS (Innovative Battery Integration System), to further accelerate the electrification journey and reduce the carbon footprint.

“Infineon is now entering a collaboration and innovation partnership with Stellantis,” said Peter Schiefer, President of Infineon’s Automotive Division. “As the world’s leading automotive semiconductor vendor, we bring our product-to-system expertise and dependable electronics to the table. Our semiconductors drive the decarbonization and digitalization of mobility. They increase the efficiency of cars and enable software-defined architectures that will significantly improve the user experience.”
