摘要
A battery management system, a battery pack including same and a method for determining a failure in a current detecting circuit. The system includes the current detecting circuit configured to detect a reference current representing a current flowing through a high current path of the battery pack, a bidirectional switch including a charging FET and a discharging FET installed on the high current path, and a control unit. The control unit detects a first voltage across the charging FET and a second voltage across the discharging FET while a first high level voltage is applied to a gate of the charging FET and a second high level voltage is applied to a gate of the discharging FET. The control unit determines a failure in the current detecting circuit based on at least one of the first voltage and the second voltage and the reference current.
