Safran Electrical & Power and Saft have signed an exclusive partnership to develop a high voltage battery system for aviation.
“The new high-voltage battery system is designed to meet the growing demand for aircraft electrification,” say the companies in a press release. “It will revolutionize onboard energy by delivering unprecedented power levels, allowing more energy to be stored and supplied over longer durations. Thanks to the combined expertise of Safran and Saft, the system incorporates high performance lithium-ion cells, cutting-edge technologies in thermal runaway containment, system management, and safety-related algorithms, ensuring the highest safety standards.
“The battery’s performance is fully scalable: modules and cells are engineered for easy adaptation to various aircraft configurations. Its modular design, with length-adjustable modules, allows seamless integration, meeting diverse installation constraints across aircraft platforms. Leveraging the latest battery technologies—from today’s lithium manganese ferro phosphate (LMFP), to solid-state cells in the near future—this new system will guarantee optimized performance tailored to the stringent requirements of aviation.
This collaboration is part of the strategic alliance between Safran and TotalEnergies signed in 2021 to jointly develop technical and commercial solutions for reducing the carbon footprint of aviation. Saft and Safran have been working together as part of an aviation battery research consortium with the support of the French Civil Aviation Authority (Direction Générale de l’Aviation Civile-DGAC).
