Problem with Voltage open-circuit (Voc) "Characterize Battery Cell for Electric Vehicles"

Hey, Im trying to charatrerize an LFP pouch cell but I'm having a problem with the simulation , first of all just for the start Im using only one data with 25 degrees , when running the code on this INPUT data:

then the Voltage open circuit get only the voltage start from here(The blue point is the missing part of the values)

and not all the values of the voltage, I mean that the battery is limited to be between 3.39 to 2.5 and the corrently volatge limit should be at least 3.65 to 2.5 ,so there is a missing values in the voltage , then I'm applying CCCV method to charge the battery to full and to 3.65 voltage but the graph of the voltage is very not similar to the battery (this is the original data from the LFP battery)

and this is the plot from the simulink

, so I came here to seak help from you guys , thanks in advance.
