The battery system diagnosing apparatus diagnoses a battery system including a plurality of battery cells having electrode tabs therein, and includes a voltage measuring unit for measuring an end voltage at every charging or discharging for each of the plurality of battery cells; and a processor for accumulating the end voltage of each battery cell measured by the voltage measuring unit over time and detecting a battery cell having a defect in the electrode tab among the plurality of battery cells based on the accumulated end voltage trend.",
