Title:  Battery Management using Estimated State of Health, State of Power, and State of Safety

Abstract: The battery management system (BMS) has been critical for merging multi-physics models and data analytics necessary for the efficiency, longevity, and safety of battery electric vehicles. The BMS is the brain of the battery system and is responsible for State of Charge (SOC), State of Health (SOH), State of Power (SOP) and State of Safety (SOS) estimation, protecting the pack, minimizing aging, accounting for cell-to-cell variability, and monitoring battery degradation in real time from field data. Accurate predictions of degradation and lifetime of lithium-ion batteries are essential for reliability, safety, and key to cost-effectiveness and life-cycle emissions. The ultimate BMS task is the detection of the onset of venting, the prediction of imminent thermal runaway, that helps manage the risk of explosions and fires from failing batteries.

Bio: Anna G. Stefanopoulou, the William Clay Ford Professor of Technology has been recognized as a Fellow of three different societies; the ASME (08), IEEE (09), and SAE (18). She is an elected member of the Executive Committee of the ASME Dynamics Systems and Control Division and the Board of Governors of the IEEE Control Systems Society. She is the Founding Chair of the ASME DSCD Energy Systems Technical Committee and a member of a U.S. National Research Council committee on the 2025 US. Light Duty Vehicle Fuel Economy Standards. She is a recipient of multiple awards and has co-authored a book, 22 US patents, and more than 350 publications (8 of which have received awards) on estimation and control of engines, fuel cells, and batteries. … and she likes small cars, scooters, e-bikes.
