Active cell balancing of Li-ion Battery pack

Hi, I'm working on a project to design an active cell balancing model for Li-ion battery pack using a battery pack. I'm having trouble starting this project. Can somebody please give an idea about how should I proceed and how to design this model?

This is so generic request, so I think you should start playing around with Simscape Power System library. Please watch these videos to start building your own model, I hope you find it useful.

Good luck!...

To get started, it's important to have a background in using Simulink and Simscape, here is some free training to help with that part.

Simulink: https://www.mathworks.com/learn/tutorials/simulink-onramp.html

Simscape: https://www.mathworks.com/learn/tutorials/circuit-simulation-onramp.html

Starting with a passive balancing example is a good start, and then you can add the circuitry to implement whatever approach to active balancing that you want to use: https://www.mathworks.com/help/physmod/sps/ug/lithium-pack-cell-balancing.html?searchHighlight=passive%20cell%20balancing&s_tid=srchtitle_passive%20cell%20balancing_1
