Steps to reproduce
A constant current--constant voltage (CC-CV) charging regime is followed to fully charge the battery before conducting an OCV-SOC test. A low current slow discharge--charge of the battery is pursued to perform the OCV-SOC test. (i) A constant current is supplied to the battery until the terminal voltage reaches 4.2V. (ii)The terminal voltage is maintained at 4.2V for constant voltage charging until the current drops to 0.01A. (iii)The battery is rested for one hour. (iv)A constant current of C/30=0.1A, is supplied to slowly discharge the battery for thirty hours until the SOC reaches 0%. A rest of 1 h follows, before the battery is charged back again by C/30 for thirty hours until the SOC reaches 100%. The battery terminal voltage and current data recorded by Arbin cycler during the OCV experiment is attached in files. The OCV-SOC model can then be developed based on the traditional combined+3 model, from which tabular models can be developed.
