I have data for Voltage, current of a battery for a particular duration of time. During this time battery is charging and discharging multiple time. I have the OCV charts with SOC, Discharge and charge voltages. I would like to know how to calcuate the rated capacity of the battery from this data, so that i can calculate the SOH of the battery.
I tried to use the colomb count method. For one point i considered the battery relaxation zone, where battery voltage is equal to OCV of the battery. this gives me the chance to get dorectly SOC value. How do i consider the other point, so that i can use that in the CCM formula, so that i can calculate the rated capacity. Thanks alot in advannced.
