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
