EAS Batteries wurde mit zwei neuen Projekten im Bereich der Raumfahrt betraut – für Anwendungen im erdnahen Orbit und in der Technologieentwicklung für zukünftige Space-Anwendungen. Die Projekte für die Kunden NASA und Reflex Aerospace zeigen die Bandbreite und Innovationskraft der EAS-Technologieplattform.
With two new space-related projects, EAS Batteries reinforces its role as a trusted technology partner for demanding applications beyond Earth. The current developments range from cell testing for future space missions to battery systems for satellites in Low Earth Orbit.
For NASA, EAS is testing new cell formats and materials under extreme conditions – including improved safety behaviour and energy density. Reflex Aerospace relies on a long-life, cost-efficient battery system for a satellite in Low Earth Orbit, designed for a five-year mission duration. These projects clearly demonstrate the flexibility and performance of the EAS technology platform – ready to power the next generation of space exploration.
#NASA 🪐: Cells for Future Space Applications
As part of a new collaboration with NASA, EAS Batteries is conducting comprehensive testing on advanced lithium-ion cells to support future space missions. The focus of this project is to qualify new cell technologies that meet the extreme demands of aerospace environments.
Cylindrical cell formats—such as the 46900 design—are frequently used in spaceflight applications due to their mechanical robustness and heritage suitability, and are the focus of this phase of testing.
Thanks to its long-standing expertise in cylindrical cell formats and its proven track record in space applications, EAS meets this requirement. EAS has already contributed to several missions with its legacy cells, which were specifically engineered for aerospace platforms. The current testing project centers on 46900-format lithium-ion cells, with the goal of optimizing their performance for space use. Key objectives include improving specific energy density (Wh/kg), enhancing safety performance through the prevention of thermal runaway, and ensuring manufacturability using EAS’s proprietary production technologies.
These efforts form the foundation for the next generation of high-performance cells, capable of operating reliably in the harsh conditions of space.
#REFLEX AEROSPACE 🛰️: Battery System for Low Earth Orbit Satellites
EAS and Reflex Aerospace (Germany) have partnered to develop a cutting-edge battery system for a satellite operating in Low Earth Orbit (LEO) – typically up to 1,000 km altitude. Energy management in this orbit is particularly challenging, as satellites are regularly eclipsed by the Earth and rely entirely on battery for supplying operational power.
To meet the mission's energy requirements and a five-year operational lifetime, EAS's proven 341440 cell was selected. The collaboration includes designing a customized battery pack and integrating a suitable Battery Management System (BMS). An electrical model for ground testing is currently in development, marking a key milestone in the project. The entire system is engineered according to New Space principles: delivering mission-critical reliability and performance in a cost-optimized solution.
These projects underscore EAS Batteries’ position as a key partner for advanced space applications – from cell development and system integration to qualification for orbit and beyond.
