본 발명은 제어기가 보조배터리의 릴레이를 제어하는 방법에 있어서, 보조배터리의 SOC 유지모드에서 LDC(Low DC/DC Converter)가 전장부하에서 요구하는 전력을 공급할 수 있는지 판단하는 단계; 상기 판단 결과, LDC가 전장부하에서 요구하는 전력을 공급할 수 없으면, 보조배터리의 전원이 전장부하로 공급되는 릴레이 온 상태를 유지하는 단계; 및 상기 판단 결과, LDC가 전장부하에서 요구하는 전력을 공급할 수 있으면, 보조배터리의 전원이 전장부하로 공급되지 않도록 릴레이를 오프하는 단계를 포함한다.
A method for controlling a relay of an auxiliary battery by a controller includes deciding whether or not a low direct current (DC) to DC converter (LDC) supplies power required in an electronic load in a state of charge (SOC) maintaining mode of the auxiliary battery. As a result of the decision, a turn-on state of the relay in which power of the auxiliary battery is supplied to the electronic load is maintained when the LDC does not supply the power required in the electronic load. As a result of the decision, the relay is turned off so that power of the auxiliary battery is not supplied to the electronic load when the LDC supplies the power required in the electronic load.
