Warnings in Simscape battery for Cell Balancing

14 views (last 30 days)
I have build a model for cell balancing by seeing the video recommend by matlab youtube channel but i was getting error while connecting the assive cell balancing block to minmax block so i used the unit delab block where my error was cleared but i was getting the warning as "At time 5677.000000, one or more assertions are triggered. State of charge must be less than or equal to 1. The assertion comes from: Block path: untitled/Pack1/ModuleAssembly1/Module1 Assert location: o (location information is protected) o In between line: 80, column: 26 and line: 92, column: 52 in file:
o In between line: 73, column: 39 and line: 82, column: 61 in file:"
and getting the graph where SOC is crossing '1'. Can you please help me with that warnings and the graph.
These are my build in model and the parameters thaat i used for simulation.

Hello Manoj,
Can you please give me a few more details about the battery cell you are modeling? What is the maximim voltage for your cell.
On a quick glance at your parameters, I noticed that you specified a maximum voltage level of 4.5V, which is quite high based on common Li ion chemistries. Is it possible that lowering that parameter your CCCV algorithm stays within the [0, 1] interval?
Please let me know if this helps.
Best regards,
Javier
