Rimac Technology unveiled its latest portfolio of battery and powertrain technologies at IAA Mobility 2025 this week, including solid-state battery solutions, updated eAxle platforms, and new electronic control architectures.
The company has expanded its role as a Tier 1 supplier through collaborations with global automakers such as BMW Group, CEER Motors, and Porsche.
The portfolio…
Batteries
- Next-Gen technology: Developed with ProLogium and Mitsubishi Chemical Group, this solid-state system combines advanced cell technology with innovative housing solutions to increase safety and energy density.
- Evo technology: Based on 46XX Gen2 NMC cells and featuring a thermoplastic composite housing co-developed with Kautex Textron, this platform integrates advanced packaging and thermal management for high-performance applications.
- Hybrid technology: Built on 46XX and 2170 cell formats, this platform supports scalable architectures for both high-energy and high-power hybrid packs, incorporating cell-to-pack design with advanced safety and thermal management.
Powertrains
- SINTEG 300 & 550: Compact single-motor eAxles with power density exceeding 8 kW/kg and torque density over 90 Nm/kg. Configurable in CoAxial or Offset layouts, these platforms deliver between 150–360 kW and 2,500–6,250 Nm for a wide range of vehicle segments.
- High-torque XXL axle: Entering production in 2026, this dual-motor eAxle will deliver over 11,000 Nm of torque with >95% peak efficiency. Industrialization is underway at Rimac’s facilities in Croatia.
Electronics and controls
Rimac is introducing a portfolio of domain and zonal ECUs powered by NXP’s S32E2 real-time processors. By consolidating multiple traditional ECUs into centralized domain controllers, these systems reduce complexity, cost, and weight while supporting software-defined vehicle architectures.
The ECUs manage functions including torque vectoring, battery management, body controls, and power distribution, with real-time performance and OTA update capability.
The new technologies will be produced at Rimac’s Croatian facilities, which span more than 95,000 m² of manufacturing space across two sites, anchored by the €200 million Rimac Campus.
