ECEA 5730 Introduction to Battery Management Systems

1st course in the Algorithms for Battery Management Systems Specialization

Instructor: Gregory Plett,PhD, Professor

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.

Prior knowledge needed:A Bachelor’s degree in Electrical, Computer, or Mechanical Engineering, or a B.S. degree with undergraduate-level competency in the following areas: Math: Differential and integral calculus, operations with vectors and matrices (mechanics of linear algebra), and basic differential equations, Engineering: Linear circuits (modeling resistors, capacitors, and sources), Programming: MATLAB, Octave, or similar scientific program environment

Learning Outcomes

  • 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.

Syllabus

Duration: 5 hours

In this module, you will learn some important terminology used to describe battery cells and will learn the principles of operation of standard electrochemical battery cells.

Duration: 5hours

In this module, 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.

Duration: 6 hours

In this module, you will begin to learn about BMS requirements, and will study the requirements for sensing and high-voltage control in detail.

Duration: 5 hours

In this module, you will continue to learn about BMS requirements, studying requirements for protection, interface, performance management, and diagnostics in detail.

Duration: 2hours

In this module, you will learn in more detail than before how lithium-ion cells are made and how they can fail.

Duration: 2hours
