Abstract
(EN) An apparatus for managing a battery according to one embodiment of the present invention comprises: a feature value extraction unit configured to extract a feature value of a learning battery for each charge/discharge cycle; a first state determination unit configured to determine a state of the learning battery for each charge/discharge cycle on the basis of the feature value extracted by the feature value extraction unit and a reference value preset to correspond to the feature value; a labeling unit configured to set a label for the feature value of the learning battery for each charge/discharge cycle on the basis of the state of the learning battery determined by the first state determination unit; a model learning unit configured to learn a classification model for determining a state of an analysis battery on the basis of the feature value for which the label is set by the labeling unit; and a second state determination unit configured to determine the state of the analysis battery on the basis of the classification model learned by the model learning unit.
