Advancing Batteries through Physics-based Control: An Automotive Perspective

The combination of electrochemistry and control has the potential to improve energy storage devices' performance and prolong their life once deployed in the field. In this talk, Professor Onori will share the ongoing research journey she has taken with her students in tackling research questions related to the design, estimation, control and optimizing of battery systems leveraging the rigorous approach from control theory. Starting from a newly developed macroscale lithium-ion battery model, Professor Onori will move to the design of model-based estimators for real-time degradation prediction and will also discuss the challenges to accurately predict the behavior of interconnected cells that form a battery pack. Finally, Professor Onori will shed light on the importance of optimal control tools in optimizing battery systems used in real vehicles. In particular, she will show how new generation of electrified military vehicles can be optimized using recent tools developed in the Onori Lab at Stanford. Professor Onori will close by highlighting open challenges in the field and new perspectives for next- generation electrochemical energy storage systems.
