Dynamic Model Reduction for Battery Repurposing in Human Space Flights

The goal of this project is to develop a dynamic model reduction (DMR) framework for battery “state-of-health” and “state-of-safety” monitoring in human space flights that enables: i) maximal characterization of lithium-ion (Li-ion) batteries; ii) in physics-based terms; iii) based on the available cycling data; iv) at each stage of the battery life; and v) in the required range of operations. Maximal characterization of in-service batteries is critical to develop physics-based informed decisions on repurposing batteries during human space flights.

This project will benefit NASA and others by developing a dynamic model reduction (DMR) framework for accurate monitoring of lithium-ion batteries in human spaceflight. By maximizing characterization with limited data; this approach enhances battery reliability; informs decisions on repurposing; and addresses logistical challenges as more diverse batteries are introduced in future missions.

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
