ProLogium announced progress in its collaboration with Rimac Technology on next-generation electric vehicle battery pack development. The companies signed a Memorandum of Understanding (MOU) in September 2025 to develop a next-generation battery platform and have completed a battery pack concept mockup, which will be displayed at the 2026 Paris Motor Show. The next phase will focus on developing a functional battery segment to establish a basis for testing the thermal management and cell-integration concepts and support battery pack applications in the battery electric vehicle (BEV) market.
The collaboration combines ProLogium’s next-generation cell technology with Rimac Technology’s battery system development expertise, focusing on a pouch cell-to-pack architecture. Through a staged development path from concept mockup to functional battery segment, full-scale functional battery pack and in-vehicle testing, the companies will progressively evaluate cell and system integration approaches, connecting next-generation cell technology with automotive product development.
From Concept Mockup to Functional Hardware
Bringing cell technology into automotive applications requires more than cell-level performance. It also involves addressing thermal management, cell integration and battery pack architecture at the system level. With battery pack integration at its core, the collaboration brings together cell technology and systems engineering to examine the design requirements for next-generation batteries in automotive applications. The completed concept mockup is an initial milestone in this development process. The ongoing development will move the project from a conceptual representation toward functional hardware, using a battery segment as the platform for subsequent testing. This work will assess the feasibility of thermal management and cell-integration concepts and inform full-scale battery pack development. By developing a battery segment before expanding to a full-scale system, the companies will gather test results and design feedback at each stage to assess whether the integration approach can meet automotive battery-systems requirements.

Vincent Yang, Founder and CEO of ProLogium, said: “Since jointly announcing our collaboration with Rimac Technology at IAA in 2025, both teams have continued to advance the project, translating our shared technical vision into concrete engineering development work. What we are presenting at the Paris Motor Show is the baseline of that collaboration. Building on the completed concept mockup and the functional segments currently in development, we are preparing to move into the development and production of a functional battery progressing toward a full-scale battery pack and subsequent vehicle integration validation. Bringing next-generation batteries to the automotive market requires more than cell technology. It also takes the engineering expertise to integrate those cells into a battery pack with optimized architecture and thermal management. We look forward to combining our technical strengths through hardware development and testing to address the engineering challenges of automotive integration and translate the value of next-generation cell technology into solutions that can be adopted in vehicles.”
Daniel Kišić, Principal Product Architect of Rimac Technology said: “Rimac Technology is developing a scalable cell-to-pack integration technology for solid-state pouch cells, designed to meet and exceed the requirements the automotive industry is expected to set over the coming decade. A wide range of integration solutions is currently being evaluated and tested in parallel on functional battery segments, covering thermal management, swelling management, cell integration and system-level design. Some of these solutions are oriented towards maximum energy density and reduced space and weight, while others are oriented towards delivering performance. The work starts from vehicle-level requirements and aims to improve every aspect of the battery design by reducing complexity, combining functions and reducing weight. It does so with cost in mind, while still delivering state-of-the-art charging times and power output. Once validated at vehicle level, the solution is expected to deliver significant weight savings, improving driving efficiency and extending range. OEMs could then choose between more energy on board at the same weight, a smaller and lighter battery for the same range, or any combination in between.”
A Clear Pathway to Full-Scale Battery Packs and In-Vehicle Testing
According to Rimac Technology’s current development roadmap, the functional battery segment currently in development is planned for display at CES 2027, with the full-scale functional battery pack identified as a development milestone for the second half of 2027. Subsequent targets include in-vehicle and public-road testing in the second half of 2028.These stages will progressively expand the scope of validation, from assessing integration concepts in a functional battery segment to a full-scale battery pack, followed by vehicle installation and road testing to evaluate system performance in an automotive environment. At the Paris Motor Show, the companies will present the concept mockup stage of the collaboration and outline the next steps in functional hardware development and integration validation. By combining cell technology with battery systems engineering, ProLogium and Rimac Technology will continue to advance next-generation battery integration technology development from concept design toward automotive applications.
