1. A processor-implemented battery management method, comprising:
estimating state information of a plurality of battery cells in a battery pack using a first battery state estimation model;
determining whether state information of at least one of the plurality of battery cells is to be estimated using a second battery state estimation model based on one or both of whether the state information of the at least one battery cell estimated by the first model is abnormal state information and whether a preset time has elapsed since a previous estimation of battery cell state information using the second model; and
estimating the state information of the at least one battery cell using the second model, in response to a result of the determining being that the state information of the at least one battery cell is to be estimated using the second model.
