Abstract: A method and an apparatus to estimate a battery state include a sensor, a data extractor, and a state estimator. The sensor is configured to sense charging voltage data, and the data extractor is configured to extract partial data corresponding to a section from the sensed charging voltage data. The state estimator is configured to estimate a state of a current battery using the extracted partial data.

Abstract: A battery state estimation method includes acquiring an initial value of a vector-type parameter for modeling an electrochemical-thermal (ECT) model of a battery, extracting a predetermined point from the vector-type parameter based on the initial value, generating a target parameter based on the predetermined point, to minimize an error between an actual state of the battery and a state of the battery acquired from the ECT model, and estimating the state of the battery based on the target parameter.

Abstract: A method with battery state estimation may include: generating a plurality of electrochemical-thermal (ECT) models corresponding to modeling conditions based on an arbitrary parameter of an ECT model configured to perform modeling of a battery; determining a target parameter of the ECT model based on an error between an actual state of the battery and a model-derived state of the battery obtained by a parallel operation of the plurality of ECT models; and estimating a state of the battery based on the target parameter.

Abstract: Disclosed is a battery management method including calculating a safety of a battery unit based on physical quantity data of the battery unit, monitoring for a threshold adjusting event to occur, performing a comparing with respect to the calculated safety and a threshold based on the monitoring indicating that the threshold adjusting event has occurred, the comparing being based on reference information corresponding to the threshold adjusting event, and selectively performing a feedback process to output a feedback dependent on a result of the comparison.

Abstract: A method and apparatus for detecting an abnormal state of a battery are provided. An entropy calculator is configured to calculate an information entropy based on battery estimation information and battery measurement information. The battery estimation information corresponds to an output required from the battery, and the battery measurement information is collected from the battery. A battery abnormality determiner is configured to determine whether the battery is in the abnormal state based on the information entropy.
