ME Seminar on "Adaptive Estimation and Control of Models for Battery Electrochemistry"
Title: Adaptive Estimation and Control of Models for Battery Electrochemistry
Speaker: Scott Moura, Ph.D, UC Presidential Postdoctoral Fellow, Mechanical and Aerospace Engineering, UC San Diego
Abstract: Energy storage represents one of society’s grand challenges for the 21st century. As renewable energy generation becomes more prominent, new solutions for efficiently storing and routing energy must be found. Today’s batteries are expensive, oversized, and conservatively operated. Advanced estimation and control can unlock their full potential. That is, real-time state information and optimization enables operation near the physical limits without compromising longevity. This feature is a crucial step towards catalyzing the adoption of energy storage in electrified transportation and smart grids.
In this talk, we focus on the state-of-charge (SOC) and state-of-health (SOH) estimation problem. We cast this problem as a simultaneous state (SOC) and parameter (SOH) estimation design. Unlike most approaches, our design utilizes electrochemical models, thus enabling us to directly estimate the evolution of relevant electrochemical phenomena. This research integrates several recently developed concepts in PDE control theory, adaptive estimation, and battery model reduction. We will also explore how these estimates can be exploited to reduce charge time, enhance energy capacity, and protect against harmful degradation processes. I conclude with an overview of open questions and future research plans in energy systems and control.
