BMMS – STTR Phase I
Spectral Labs Incorporated was awarded a DOD Phase I SBIR for research and development of a battery safety system to be used for Lithium Ion batteries.

Although many off-the-shelf and semi-custom Battery Management Systems (BMS) are available, the Navy recognizes with this STTR Topic, and recent history illustrates, that a safety system with the required reliability and performance for mission critical applications has not been demonstrated. This proposal will detail the Spectral Labs Incorporated (SLI) and University of California, Davis (UCD) team’s proposed method for significantly improving Li-ion Battery Monitoring to detect the onset of cell degradation that could lead to catastrophic failure of a battery pack and providing a means to prevent such an event. It involves an innovative sensor architecture and associated diagnostic analysis algorithms based on detailed tracking of the behavior of Li-ion cells throughout their charge and discharge use cycles.
