본 발명은 연료 절약을 위해 엔진이 반복적으로 정지 및 재시동되는 ISG 시스템을 가진 엔진을 시동하기 위한 배터리 팩을 개시한다. 상기 배터리 팩은 충방전이 가능한 배터리 셀; 상기 배터리 셀에 전기적으로 연결된 가변 저항을 구비한 제1 ISG 전류 조절부; 및 상기 배터리 셀 및 상기 제1 ISG 전류 조절부에 전기적으로 연결되고, ISG 시스템의 현재 모드에 따라 상기 가변 저항의 저항값을 설정하는 배터리 관리부(BMS);를 포함한다.
A battery pack comprises a rechargeable battery (210) configured to receive charging current from a power generation module (110) in a driving mode, to supply discharging current to a starter motor (120) in a start mode and to supply discharging current to at least one load (130a, 130b) in a sleep mode, wherein charging current is not received from the power generation module in the sleep mode. The battery pack further includes a current control unit (220) configured to control the current supplied to the at least one load; and a battery management system (230) configured to monitor an output voltage of the rechargeable battery in the sleep mode and control the current control unit to control the current supplied to the at least one load in the sleep mode based on the monitored output voltage.
