Original Abstract Submitted

A system and method for detecting the degradation of a storage battery of a battery energy storage system (BESS) container includes a battery management system (BMS) coupled to the storage battery configured to collect battery operational data from the storage battery. A battery data repository coupled to the BMS receives and stores the battery operational data. A learning agent coupled to the battery data repository uses the stored battery operational data to estimate a prognostic degradation of the storage battery and train a degradation estimation model. A state of charge (SOC) estimation agent receives and uses the trained degradation estimation model to generate a real-time estimate of the SOC of the storage battery for scheduling charge/discharge cycles for the BESS container. The system and method includes updating the storage battery model parameters based on data generated during battery charge and discharge cycles that uses an expert user to review and validate the battery model parameters and a system and method used to protect the integrity of the battery data for warranty tracking of the storage battery of the BESS.
