Parameter extraction (R,C,OCV) from EV's drive cycle ?

Hi,

I want to extract equivalent circuit parameters such as R0,R1,R2,C1,C2 and OCV from Electric vehicle drive cycle (voltage vs time) to model Lithium ion battery. The car battery is made of LFP cells. Then I will compare model vs drive cycle. Anyone knows how to do it ? Any basic scripts, model, reference, equations will be useful.

Thanks in advance
