Abstract: Disclosed is a battery state of charge (SOC) determining method and a battery managing apparatus that acquires a stochastic reduced order model (SROM) and a mean using battery conservation equations acquired based on a stochastic Pseudo 2-dimensional electrochemical thermal (P2D-ECT) model, measures state information, and assimilates the state information with the SROM and the mean to determine an accurate SOC at a relatively low calculation cost.

Abstract: A method, for intelligent management of a battery is provided. The method includes detecting at least one anomaly associated with the battery. The at least one anomaly impacts one or more operations of the battery. The method includes identifying at least one portion of data from reference charging data to include the at least one anomaly for managing the one or more operations of the battery. The method further includes modifying at least one portion of data from the reference charging data based on a pre-determined logic to include the at least one anomaly. The method also includes retraining an Artificial Intelligence (AI) model based on the reference charging data upon modification for managing the one or more operations of the battery.

Abstract: Provided are a battery state measuring method and battery management system, which predict a time point when charging capacity of a battery is to be relatively abruptly reduced. The battery state measuring method includes: monitoring a change of at least one precursor related to the charging capacity of the battery with respect to a number of charging cycles undergone by the battery; and predicting that an abrupt reduction in the charging capacity of the battery is imminent when the change of the at least one precursor follows at least one pre-configured pattern of the battery that has undergone a critical number of charging cycles.
