Abstract
A battery management apparatus includes a plurality of battery cells connected to one another in at least one of a series connection or a parallel connection; a detector configured to detect electrical signals of the battery cells; a monitor configured to obtain the electrical signal for each of the battery cells and values of correlation coefficient corresponding to correlation results obtained based on the electrical signals, and to generate identification signals corresponding to the electrical signals of the battery cells based on the values of correlation coefficient and a reference value; and a storage configured to store the identification signals generated by the monitor for each of the battery cells. The monitor is configured to recognize a risk of failure of each of the battery cells based on an accumulated number of identification signals stored in the storage for each of the battery cells.
