Modeling changes in the state-of-charge open circuit voltage curve by using regressed parameters in a reduced order physics based model

A method for modeling changes in the state of charge vs. open circuit voltage (SOC-OCV) curve for a lithium-ion battery cell as it ages. During battery pack charging, voltage and current data are gathered for a battery cell. A set of state equations are used to determine the stoichiometry and state...
