Can i use battery pulse discharge data to calibrate the table-based battery model?

Hello,

I am in between developing a lithium ion battery pack for thermal analysis. For this, i have taken table-based battery model. I also have DC electronic load tester which can perform pulse discharge test of the lithium ion cell. As far as i know, the HPPC test data is required to calibrate the battery cell model which is based on pulse charge and discharge of the lithium ion cell, but i only have discharging option. Can i calibrate my battery pack model with the experimental data of pulse discharge? Also, if any other option is available, please let me know.

Thank you.

Hi Sudeep. Check out this example on fitting equivalent circuit battery models to test data. The process works with whatever data you give it, but if you provide only discharge data, you will only characterize the discharge behavior. You would expect different resistance in charge and discharge operation.
