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.
