Abstract: 
As lithium-ion battery technology matures, there has been an accelerating push to improve battery performance and safety by understanding their dynamics and using algorithms to manage them more effectively. In this talk, I will discuss three problems that apply ideas from control theory to batteries, by computing: i)  scalable bounds for thermal hotspots using relaxation systems theory,  ii) fast charging protocols as optimal control problems that exploit positivity, and iii) battery pack models that are contracting differential algebraic systems. The goal of the talk is not only to demonstrate how control theory can lead to better batteries, but also how battery applications can also motivate new control theory problems.
