Saturday Morning Physics | Battery Management System: Engineering a Guardian Angel for Lithium-Ion Batteries

Anna Stefanopoulou, William Clay Ford Professor of Technology (U-M Mechanical Engineering)

The challenge and opportunity of battery lifetime prediction The challenge and opportunity of battery lifetime prediction
The challenge and opportunity of battery lifetime prediction
From the Rosetta-Philae spacecraft landing three billion miles away from Earth to the daily commute of an electric vehicle, the battery management system (BMS) has been critical for 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, which helps manage the risk of explosions and fires from failing batteries.

This talk will be live in ROOMS 170 & 182 Weiser Hall. You can also watch the talk/Q&A, live, on YouTube: https://www.youtube.com/watch?v=cz0l5TJk-LE
