When studying the pack voltage using termal analysis for both newly and old packs, why does the curve just display a falling trend instead of genral ocv curve of a battery?

during the process of thermal analysis of the pack voltage for both new and used battery packs. My question is why the pack voltage merely decreases when simulating using the link provided and obtaining the output that appears in the link. The voltage of the discharge pack appears to be similar to OCV curve.

Hello Shivanshu,

In the model you have linked, the battery is not being loaded with a CC-CV profile but is using a 2C profile (e.g. constant current overall the entire simulation). This is stated in the description of the shipping example

This is the reason why the voltage you observe keeps decreasing instead of reaching a plateau as you would expect in a CV phase (but as stated above the CV phase does not occur in this example).

Hope this helps.

Best,

Lorenzo
