Abstract

A method and system for identifying parameters of an electrochemical model for characterization and/or operational management of batteries. Battery performance data is collected under various conditions, applying an electrochemical model to simulate battery chemistry and degradation. The model parameters are segmented into subsets related to specific conditions and aging effects. An optimization framework then estimates each subset of parameters by resolving individual optimization problems based on the performance data. These estimated parameters are used to refine the electrochemical model, which is subsequently employed for further characterization and management of batteries.
