Rimac unveils solid-state battery technology at the IAA event
Croatian electric vehicle technology company, Rimac Technology, a subsidiary of the Rimac Group, is set to showcase its next-generation electrification technologies at the IAA Mobility 2025 in Munich.
Rimac's lineup for the showcase is impressive, featuring a variety of advancements from different fields. Among the highlights are the High Torque XXL Axle, slated for production with a global automaker in 2026, and the SINTEG 300 and 550, ultra-compact electric axles delivering over eight kilowatts per kilogram.
The High Torque XXL Axle promises an astounding 11,000 Nm of torque and over 95% efficiency, making it a significant leap in electric drivetrain systems. On the other hand, the SINTEG axles are compact yet powerful, capable of up to 25,000 RPM and modular power levels between 150 and 360 kW.
In collaboration with ProLogium and Mitsubishi, Rimac has developed the Next-Gen Battery Platform, which is likely to be the most significant IAA debut. This new platform is built on 46XX-Gen2 NMC cells and enhanced with a newly developed battery housing, forming the new Evo Battery Platform. The Evo Platform, combined with an optimized thermal management system, represents the next step in performance-ready and production-near battery systems.
Rimac also presents domain and zone control units based on NXP S32E2 processors, aiming to simplify vehicle architectures by replacing multiple conventional control units. These control units reduce costs, weight, and enable software-defined vehicle functions with OTA updates.
Global automotive manufacturers currently collaborating with Rimac Technology to develop their electric mobility solutions include Volkswagen Group, which works with Rimac as a Tier-1 supplier advancing electrification technologies such as next-generation solid-state batteries and electric axles. In the past twelve months, Rimac has announced partnerships with BMW Group, CEER Motors, and Porsche.
The showcase in Munich will also feature next-generation batteries with solid-state cells, which ProLogium has been working on with Mercedes-Benz for some time. Rimac Technology, with its 1,000 employees, covers the entire process from concept development to series production, aiming to emphasize its role as a Tier 1 supplier to global automotive manufacturers.
Rimac's new headquarters campus, located on the outskirts of Zagreb, Croatia, is designed to ensure both scalability and technological excellence. The 95,000 square meter facility is where these groundbreaking electrification solutions are being developed.
With its presence at IAA Mobility 2025, Rimac Technology is set to reaffirm its position as a leading innovator in the electric vehicle industry. The event promises to be a showcase of the future of mobility, and Rimac's contributions are sure to be a highlight.
