A battery management system may include: a charge control switch disposed in a high current path between a plurality of pack terminals and a battery module; and a controller configured to detect a cell voltage of each of a plurality of cells included in the battery module and a charging current flowing through a high current path, to determine an overvoltage state of the battery module based on presence or absence of the charging current and the cell voltage of each of the cells, and to turn off the charge control switch when the battery module is determined to be in an overvoltage state.
