This course can also be taken for academic credit as ECEA 5730, part of CU Boulder’s Master of Science in Electrical Engineering degree.
This course will provide you with a firm foundation in lithium-ion cell terminology and function and in battery-management-system requirements as needed by the remainder of the specialization. After completing this course, you will be able to:
- List the major functions provided by a battery-management system and state their purpose
- Match battery terminology to a list of definitions
- Identify the major components of a lithium-ion cell and their purpose
- Understand how a battery-management system “measures” current, temperature, and isolation, and how it controls contactors
- Identify electronic components that can provide protection and specify a minimum set of protections needed
- Compute stored energy in a battery pack
- List the manufacturing steps of different types of lithium-ion cells and possible failure modes
Overview
Syllabus
-
- Battery Boot Camp
- This week, you will learn some important terminology used to describe battery cells, and will learn the principles of operation of standard electrochemical battery cells.
- How lithium-ion cells work
- This week, you will learn some of the principal advantages of lithium-ion cells versus standard electrochemical battery cells, what are their primary components, and how they work.
- BMS sensing and high-voltage control
- This week, you will begin to learn about BMS requirements, and will study the requirements for sensing and high-voltage control in detail.
- BMS design requirements 2-5
- This week, you will continue to learn about BMS requirements, studying requirements for protection, interface, performance management, and diagnostics in detail.
- How are cells made? How can they fail?
- This week, you will learn in more detail than before how lithium-ion cells are made and how they can fail.
