ProLogium and Rimac Technology advance next‑generation EV battery integration
- MOU signed in September 2025 to develop a next‑generation pouch cell‑to‑pack EV battery platform.
- Concept mockup completed and displayed at the 2026 Paris Motor Show.
- Functional battery segment targeted for CES 2027; full‑scale pack slated for H2 2027.
- In‑vehicle and public‑road testing expected in the second half of 2028; work focuses on thermal, swelling and cell‑integration solutions for solid‑state pouch cells.
Partnership scope
The collaboration pairs ProLogium’s next‑generation cell technology with Rimac Technology’s battery‑system development expertise to develop a pouch cell‑to‑pack architecture for BEV applications. The partners signed an MOU in September 2025 and have completed a concept mockup that will be shown at the 2026 Paris Motor Show.
Development approach
The project follows a staged path: concept mockup, development of a functional battery segment, a full‑scale functional battery pack, and in‑vehicle testing. The battery segment will be used to validate thermal management, swelling management, cell integration and system‑level design before scaling to a full pack.
Technical focus
Development work targets system‑level engineering challenges beyond cell performance, including thermal management, cell integration, pack architecture, and weight and complexity reduction. Rimac Technology is evaluating multiple integration solutions for solid‑state pouch cells to balance energy density, performance, weight and cost while meeting expected automotive requirements.
Timeline and milestones
The functional battery segment is planned for display at CES 2027, the full‑scale functional battery pack is a milestone for the second half of 2027, and in‑vehicle/public‑road testing is targeted for the second half of 2028. Each stage will expand validation from component‑level concepts to vehicle‑level performance.
