Abstract
A BMS and driving method, the BMS including a sensing unit sensing voltages and currents of battery cells and an MCU determining an SOC of the battery cells and controlling charging and discharging based on cell voltages and currents of the battery cells, wherein the MCU includes an SOC measurer measuring first SOCs and, after a predetermined duration, second SOCs of the battery cells; and a controller determining whether a first difference value between a maximum second SOC value and the second SOCs of each battery cell is greater than a first reference value or determining whether a second difference value between the first and second SOCs of respective battery cells is greater than a second reference value, and determining which battery cell is shorted when the first difference value is greater than the first reference value or when the second difference value is greater than the second reference value.
