  "textContent": "A battery management system and a driving method thereof are disclosed, which may detect a short battery cell capable of causing or having caused short among a plurality of battery cells (210, 220, ...) during a parking period of a vehicle. The battery management system includes a sensing unit (10) for measuring a cell voltage and a cell current of each of a plurality of battery cells (210, 220, ...) and an main control unit (20) for measuring an state of charge of each of the battery cells (210, 220, ...) to control charge and discharge by utilizing the cell voltage and the cell current of each of the battery cells (210, 220, ...). The main control unit (20) measures a first state of charge (SOC1_n) of each of the battery cells (210, 220, ...) in a key-off state and a second state of charge (SOC2_n) of each of the battery cells (210, 220, ...) in a key-on state after the key-off state. The main control unit (20) utilizes the first state of charge (SOC1_n), the second SOC (SOC2_n), and a time period between the first and second states of charge to determine a short battery cell among the plurality of battery cells (210, 220, ...).",
