battery module simulation result

I have design simulation strategy according to MATLAB official video on Youtube but I couldnt reach similar result. As the video, The simulation comes up 44 V middle of cell but I have currently obtain 4 V I couldnt solve this problem I couldnt understand why it was happenned.

I am trying to understand all battery builder app . I have design but I couldnt solve the problem about the battery simulation strategy.

Hi Bilgin,

I believe that the YouTube video that you are referring to is, https://www.youtube.com/watch?v=GDJkpv-_rSM as it fits the description of your question.

I have noticed that you have used the R2023b version of MATLAB. The video is explained on R2022b version of MATLAB where the logic of how voltages from lumped cells are displayed, changed from R2023a onwards.

In the YouTube video, the probed variable is 'vCellModel', which represents the model voltage, not the cell voltage. But for versions since R2023a, ‘vCellModel' was replaced with 'vCell,' the cell-level voltage. This is the reason why you are not able to replicate the effect you see in the video

You can refer to the following MATLAB answer which answers a similar query

Thank you.
