The present invention provides a system for controlling a relay of an auxiliary battery capable of improving fuel efficiency of an environmental-friendly vehicle, and a method thereof. The method for controlling a relay of an auxiliary battery by a controller comprises the following steps of: determining whether a low DC/DC converter (LDC) supplies a power required by an electric field load in a state of charge (SOC) maintaining mode of the auxiliary battery; maintaining a relay on-state that the power of the auxiliary battery is supplied to the electric field load, as a result of the determination, if the LDC cannot supply the power required by the electric field load; and turning off the relay so that the power of the auxiliary battery is not supplied to the electric field load, as a result of the determination, if the LDC can supply the power required by the electric field load.

    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.
