A battery management system including a first connection unit, a first slave controller and a master controller. The first connection unit electrically connects a first battery cell included in a first battery group to the first slave controller. Power from the first battery group is supplied to the first slave controller through a first power line included in the first connection unit. The first slave controller determines a first reference voltage value indicating a voltage of the first battery cell during the execution of the first communication mode, and determines a first comparative voltage value indicating a voltage of the first battery cell during the execution of the second communication model. The master controller determines whether the first power line has an open circuit fault based on the first reference voltage value and the first comparative voltage value.
