Hybrid Battery Power System for USSF Satellite Applications

In this SBIR Phase I effort, Haylon Technologies proposes to bench-test a power management system that enables ultra-energy-dense battery cells to be used in satellites, thereby dramatically extending device runtime for critical Space Force satellite batteries. Some types of batteries provide quick power but store less energy, while others hold more energy but release it slowly, similar to how sugars and fats function in biology. By using two different types of batteries in tandem with one another on a "battery hybridizer" circuit that adapts power delivery to their unique qualities, Haylon will allow batteries to toggle between high-power and high-energy battery cells, to extend the run time and lifespan of satellites with variable power loads.   In this Phase I SBIR, Haylon Technologies proposes to bench-validate a satellite-relevant battery pack that leverages a "battery hybridizer" that strategically toggles between two different cell chemistries based on a satellite's power draw patterns. This approach would enable sweeping SWAP enhancements to USSF satellite assets and other devices if proven successfully.  The novelty of this project lies in the approach to adaptively leveraging individual battery cells, even those of different battery chemistries in satellite applications. Different battery chemistries oftentimes present radically different charging and discharging profiles that require both robust switching hardware to account for as well as a comprehensive mechanism to track and respond to natural battery changes over time. Therefore, designing and de-risking this architecture is fitting work for an SBIR with the USSF. ???????
