A battery management system includes a voltage measurement unit that measures a voltage of each of a plurality of batteries; and a controller. The controller controls the voltage measurement unit to measure the voltage of each of the plurality of batteries; calculates a first deviation, which is a deviation between long-term and short-term moving average values of the voltage of each of the plurality of batteries; calculates a second deviation, which is a deviation between long-term and short-term moving average values of an average voltage of the plurality of batteries; calculates a first diagnosis deviation, which is a difference between the first and second deviations; calculates a second diagnosis deviation based on a reference value obtained by multiplying the second deviation by a threshold constant; and based on the second diagnosis deviation, diagnoses an abnormality of at least one battery among the plurality of batteries.
