Completed TRL 3 (started at 2, targeting 3)
The objective of this work is to understand the battery management protocols of hibernation of Li-ion cells and battery packs at differing SOCs during exposure to lunar day/night cycles. The objective will be achieved upon completion of survival testing for 1) single cells at high SOC, 2) independent series and parallel strings, and 3) battery packs with series and parallel string combinations.
Successful demonstration of battery hibernation and revival is a cornerstone in enabling low-cost missions to extend their durations beyond a single lunar daylight period without needing to develop new battery technologies.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — 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.
