Beschreibung
Zusammenfassung:	According to an embodiment of the present invention, an over-discharge preventing device for preventing over-discharge of a battery pack included in a vehicle comprises: a measurement unit configured to measure a voltage of a main battery installed in a battery pack according to an operation mode; and a control unit configured to determine an operation state of a charge/discharge relay connected to the main battery and control the operation mode of the measurement unit based on at least one of the determined operation state of the charge/discharge relay, whether to stop a vehicle, and a voltage of the main battery measured by the measurement unit. 본 발명의 일 실시예에 따른 과방전 방지 장치는 차량에 구비된 배터리 팩의 과방전을 방지하는 장치로서, 동작 모드에 따라 상기 배터리 팩에 구비된 메인 배터리의 전압을 측정하도록 구성된 측정부; 및 상기 메인 배터리와 연결된 충방전 릴레이의 동작 상태를 판단하고, 판단된 상기 충방전 릴레이의 동작 상태, 상기 차량의 정지 여부 및 상기 측정부에 의해 측정된 상기 메인 배터리의 전압 중 적어도 하나에 기반하여 상기 측정부의 동작 모드를 제어하도록 구성된 제어부를 포함할 수 있다.
