摘要： 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.

摘要： A processor-implemented method of estimating a state of a battery includes acquiring current information and voltage information of a battery; determining time interval values based on the acquired current information such that current integration values corresponding to the time variation values satisfy a condition; determining voltage values corresponding to the determined time interval values in the acquired voltage information; and determining state information of the battery based on the determined voltage values.

摘要： 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.

摘要： A method of estimating battery state information includes collecting battery information; partitioning the collected battery information into interval information in a predetermined range; accumulating the interval information; and estimating the battery state information based on the accumulated interval information and learning information determined in advance. A method of learning battery state information includes collecting battery information; partitioning the collected battery information into interval information in a predetermined range; accumulating the interval information; and determining learning information based on the accumulated interval information and reference information of a battery, the learning information being used to estimate the battery state information.
