Battery Management Apparatus

A battery management apparatus includes a measuring unit configured to measure a voltage of each of a plurality of battery cells, a converter connected to corresponding battery cells among the plurality of battery cells and configured to form a charge and discharge path between the connected battery cells according to an operation state of a switch included therein, and a control unit configured to receive a voltage value of each of the plurality of battery cells from the measuring unit, control the operation state of the switch included in the converter, calculate a voltage change rate of a charging cell charged by the converter according to the control of the operation state of the switch, and determine whether the charging cell is degraded based on the calculated voltage change rate.
