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!...

Hey Garima. I hope you are doing well. I am working on BMS and i am facing some difficulty in active cell balancing. can you please guide me?

Can you share your code ??

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

Hey, I dont know if you found the answer or not.

1. Just go through cell balancing documentations in mathwork, you'll get an idea.

2. Then search for "active cell balancing simulink model" in youtube, you can find few simulink model videos of two cell battery.
