Battery Control Group
University of Michigan
Welcome to Battery Control Group in the Department of Mechanical Engineering at the University of Michigan!
We work on improving the cost, safety, and lifetime of batteries using a combination of experiments, physics-based modeling, control theory, and data analytics. We are also deeply committed to the education and workforce development needed for the transition to electrification.
Our main research interests are:
Battery Safety
Battery State Estimation and Diagnostics
Battery Degradation Modeling and Lifetime Prediction
Intelligent Battery Manufacturing
Electrification Workforce Development and Education
