How can I access the Batt.K, Batt.C and Batt.lambda values which are used in battery submodel? And also I need the Current Filter parameters, Ts and Batt_Tr.

I opened the battery block as subsystem to understand how battery works, by checking the Generic Battery Model Documentation in MathWorks.

https://www.mathworks.com/help/physmod/sps/powersys/ref/battery.html

But I can't find the values in the shared datasheets. I try to match the blocks with the given charge and discharge equations and create my own battery, but I couldn't figure out why we use current filter or some of the function and constant blocks, I mean why do we multiply the Qc value by 0.9999 or it_sat by 3600.
