Short Course #3 Battery Design and Simulation
Robert Spotnitz, Instructor
Battery Design and Simulation attendees will learn how to select batteries for specific applications, and techniques for sizing and estimating performance. Attendees will also develop an appreciation for the types of battery processes that are currently amenable to simulation, the types of simulation models available, and how these models can be applied to simulate battery performance. This introductory course requires no prior experience in battery modeling. The following major topics are covered.
Survey of battery systems (markets, applications, general behavior).
Principles of battery design (sizing, tab placement, thermal management, charging).
Equivalent circuit modeling of battery systems (discrete circuit elements, applications in circuit design, state of charge determination, state of health determination).
First principles’ modeling of battery systems (fundamental laws, cell models for specific chemistries, battery versus cell design, numerical methods).
Simulation of battery performance (discharge/charge behavior, thermal behavior, fade, abuse).
About the Instructor
Robert Spotnitz is President of Battery Design Co. (www.batdesign.com). He earned a PhD in chemical engineering from the University of Wisconsin-Madison, and an MS in computer science from Johns Hopkins University. He was a founding member of the Electrochemistry Department of W. R. Grace & Co.; and over twelve years, made many significant technical contributions such as new types of separator materials for advanced batteries, electrochemical processes, and new inorganic materials. He then worked at Hoechst Celanese (Celgard Division) where he established a Battery Applications Laboratory, and served as an internal consultant on battery technology for Technical Service, Marketing, Development, and Corporate Research; this work contributed to the successful introduction of tri-layer shutdown separators for lithium-ion batteries. Before starting Battery Design Co., as Director of PolyStor’s Advanced Products, Dr. Spotnitz led the development of large lithium-ion batteries for hybrid electric vehicles. Currently, Dr. Spotnitz’s work is focused on performance modeling of lithium-ion batteries; and he also serves as a consultant to a number of organizations including USABC.
