    摘要： The present disclosure discloses a battery protection circuit and a method thereof for protecting a battery pack. The battery protection circuit comprises a hardware protection circuit, a software protection circuit and a current detecting circuit. When the battery pack is not in the active status, the hardware protection circuit is used to execute a protective operation; and when the battery pack is in the active status, the software protection circuit is used to execute the protective operation. Furthermore, the hardware protection circuit is electrically connected to the software protection circuit to detect a status of the software protection circuit. When the battery pack is in the active status, the software protection circuit is used to execute the protective operation, and when the software protection circuit is in an abnormal status, the hardware protection circuit is used instead to execute the protective operation.
