Zusammenfassung:	The present invention relates to a cooling apparatus for charging hydrogen, which is to cool hydrogen for charging high-pressure hydrogen, and a method for charging a hydrogen vehicle using the same. More specifically, the present invention relates to a cooling apparatus for charging hydrogen and a method for charging a hydrogen vehicle, which are able to minimize the starting time, reduce the operation cost and installation cost, and reduce the volume of a heat exchanger. In accordance with the present invention, the cooling apparatus for charging hydrogen can comprise: a heat exchange unit which cools hydrogen inputted from a hydrogen tank and outputs the cooled hydrogen to a dispenser; a freezing unit which cools a refrigerant injected into the heat exchange unit; and a heat storage chamber which accommodates the heat exchange unit inside. In accordance with the present invention, the method for charging the hydrogen vehicle can comprise: a pre-cooling step to operate the freezing unit and pre-cool the heat exchange unit to -40 to 0℃; a hydrogen cooling step to cool the hydrogen in the hydrogen tank by circulating the hydrogen in the heat exchange unit; a hydrogen charging step to output the cooled hydrogen to the dispenser and charge the hydrogen into the hydrogen vehicle; and a low temperature maintaining step to maintain the temperature of the heat exchange unit to be -40 to 0℃. 본 발명은 고압의 수소 충전을 위해 수소를 냉각하기 위한 수소 충전용 냉각 장치 및 수소 자동차 충전 방법에 관한 것으로, 구체적으로는 시동시간을 최소화하고 운전비용 및 설치비용을 절감할 수 있으며, 열교환기의 체적을 줄일 수 있는 수소 충전용 냉각 장치 및 수소 자동차 충전 방법을 제공하기 위한 것이다. 본 발명의 수소 충전용 냉각 장치는 수소 탱크로부터 입력받은 수소를 냉각시킨 후 냉각된 수소를 디스펜서로 출력하는 열교환 유니트; 상기 열교환 유니트에 주입되는 냉매를 냉각하는 냉동 유니트; 및 상기 열교환 유니트를 내부에 수용하는 축열조를 포함하는 것일 수 있다. 본 발명의 수소 자동차 충전 방법은 상기 냉동 유니트를 가동하여 상기 열교환 유니트를 -40 내지 0 ℃ 로 예냉하는 예냉 단계; 상기 수소 탱크의 수소를 상기 열교환 유니트에서 순환시켜 수소를 냉각하는 수소 냉각 단계; 냉각된 수소를 상기 디스펜서로 출력하여 수소 자동차에 수소를 충전하는 수소 충전 단계; 및 상기 열교환 유니트를 -40 내지 0 ℃ 로 유지하는 저온 유지 단계를 포함할 수 있다.
