Infineon, Stellantis Partner for EV Ambitions

Electric vehicles are becoming the automobile industry’s cornerstone in transitioning to sustainability, but developing the next generation of EV platforms comes with unique challenges. As cars become more electrified and software-driven, traditional power distribution methods are insufficient. Automakers must adopt more innovative, integrated technologies to enhance efficiency, reduce costs, and maximize range without compromising safety or performance. For Stellantis, achieving these goals requires innovative power architectures designed to meet EV systems’ growing complexity.

Infineon and Stellantis aim to address these challenges through a multifaceted collaboration built on supply and capacity agreements. This partnership combines Infineon's proven automotive semiconductor expertise with Stellantis' innovative EV platforms to enhance electric vehicles with smart power switches, silicon carbide semiconductors, and advanced microcontrollers.

Infineon’s Key Technologies

PROFET Smart Power Switches: These advanced electronic switches replace traditional vehicle fuses. Traditional fuses are single-use and must be replaced if they blow, but smart power switches can reset themselves and provide more precise control over the electrical system. This helps reduce the wiring and allows for better vehicle power network management. Stellantis will be among the first automakers to implement this technology across its platforms.

Silicon Carbide (SiC) CoolSiC Semiconductors: Silicon carbide makes more efficient semiconductors than traditional silicon-based ones. SiC technology enhances EV power modules’ performance and efficiency, thus reducing energy losses and extending vehicle range. Stellantis aims to standardize power modules using Infineon’s SiC solutions, ensuring cost-effective scalability.

AURIX Microcontrollers: Microcontrollers are small computers on a single integrated circuit that control various vehicle functions. The AURIX microcontrollers for automotive applications are known for their high performance and safety features. They will be used in Stellantis’ new STLA Brain zonal architecture to help simplify the wiring and improve the vehicle electronics’ overall efficiency and reliability.
