This course can also be taken for academic credit as ECEA 5731, part of CU Boulder’s Master of Science in Electrical Engineering degree.
In this course, you will learn the purpose of each component in an equivalent-circuit model of a lithium-ion battery cell, how to determine their parameter values from lab-test data, and how to use them to simulate cell behaviors under different load profiles. By the end of the course, you will be able to:
- State the purpose for each component in an equivalent-circuit model
- Compute approximate parameter values for a circuit model using data from a simple lab test
- Determine coulombic efficiency of a cell from lab-test data
- Use provided Octave/MATLAB script to compute open-circuit-voltage relationship for a cell from lab-test data
- Use provided Octave/MATLAB script to compute optimized values for dynamic parameters in model
- Simulate an electric vehicle to yield estimates of range and to specify drivetrain components
- Simulate battery packs to understand and predict behaviors when there is cell-to-cell variation in parameter values...

Superb course, well explained. The instructor made difficult concept look so easy. Honors content has some good insights into design of electric vehicles battery pack.

Useful information, but definitely disappointing that you can easily get 100% throughout the course and then be caught by surprise on a capstone project that requires significant Matlab knowledge beyond the scope of the rest of the course material.

The course is good. I did learn a lot. But, it will be more useful to provide some guidance in the capstone project. For example, some testing data to validate before submission. It would make it easier to troubleshoot. The submission feedback did not provide enough information to know why the code did not pass.

Would have been a lot better if the final programming assignment had any support for questions.

The course explains the cell model in a very simple way. The way the professor has developed the course structure is awesome. He has incremented by little steps from video to video due to which you will never feel the complexity in understanding at all. The main plus point of this course is the MATLAB codes. Writing everything for the first time may be complex, time consuming and tiresome. However, the professor has provided few codes and explained them in detail. For those who don't have experience in MATLAB programming, please do learn it before enrolling in the course.

Excelent course for learning battery modeling and simulation. The concepts on modeling and simulation can be applied to any application besides electrochemical batteries.

very interesting course. exposed me to how a model is created on the basis of lab tests in order to simulate a real physical phenomenon/system. using mathematical equations to describe the model and finding system specific parameter values to describe a particular system under study.

the instructor is really good and explains everything really well so every student enrolled in the course understands the concepts and steps taken . results obtained by the execution of the code make it even more interesting and insightful and helps student see the beauty of simulations and how we can see results of a model even without actually tediously conducting hours of tests and collecting data which can just be replaced by few seconds of computation to give a general idea(if not exact) of the actual behavior of the system. beautiful.

Very good course which explains how to simulate lithium ion cells and battery packs under different charge, discharge and temperature using equivalent enhanced self correcting model for accurate estimation of parameters under working load conditions.

The pathetic thing is the assignments are evaluated for exact answer only like no range in answers even for decimal answers and mentors are not active also never helps even in discussion forums.

Great course. I learned how to simulate a battery pack here. My only criticism is that the ocv-soc test and data shown here do not match the industry trend of using incremental ocv tests. If such standard tests were used it would have been easier to relate to battery research and use plethora of data available online for battery modeling.

This course is great for people who want to dig deeper into the world of Lithium-ion batteries and their electrical behavior, The MATLAB coding has been explained lucidly. I would recommend writing your own code, using the mathematical models derived in this course, to get a better understanding of the subject.

the course was really great! I would like to ask for a change in the way the quizzes are give, if any preset mathematical constants are used, do include their preferred values that we must use ( like say that Pi=3.14159 must be used or something)

otherwise, the course and the instructor were great!

Concepts are explained with clearness and content is very interesting. The only thing that I would modify is the final exam, I think that using the modeling techniques learned during the course would be more useful than tweaking manually the model parameters. Great course

It is very interesting to understand how the battery cell models can be developed by just using the simple tools in Octave coding. The course material is really amazing and the teaching pattern is also great. I'm looking forward to finish this whole specialization.

Excellent content. The instructor is immensely knowledgeable. I would recommend this course 10/10 even for experienced professionals. But Coursera needs to improve their grading system on the projects. It only accepts answers in a certain format.

This, together with Course 3 (SOC estimation) was the most interesting course in the specialization. The course simply explains the dynamic model of lithium battery, and how to estimate model parameters based on lab test data.

The content for this course is great, the duration of each topic was clearly illustrated. Thanks to Dr.Gregory L Plett and Coursera team for providing me a wonderful opportunity to learn.

Thank You

This specialist is a great combination of material, electrical and computer engineering, this cross-discipline knowledge leads to a BMS design which is very practical, you will have a clear purpose of learning.

Good class for the fundamentals. I would highly recommend the honors if you don't use Octave. It's a good crash course. Also, take the time to look at some for the underlying code supplied for each lesson.

Dr. Gregory Plett has undescribable teaching skills and delivered more than 100 % in this specialization.

Again I am really thankful to Dr. Gregory Plett and Coursera for providing such an amazing platform.

Great description of Cell Model. Someone with basic electrical knowledge can easily learn the concepts.
