사용자가 충전부(50)를 차량(100)과 접속하면(S10), 감지부(60)가 차량(100)의 충전 상태를 감지한다(S20). 즉, 충전노즐부(52)가 차량(100)과 연결되면, 감지부(60)는 각 차량(100)의 수소연료 저장 상태와, 수소연료 충전량을 조작하는 충전조작부(51)의 조작신호를 제어부(70)로 전송하고, 각종 신호를 수신한 제어부(70)는 분배부(20)와 혼합조절부(40)를 각각 제어한다.When the user connects the charging unit 50 to the vehicle 100 (S10), the sensing unit 60 detects the charging state of the vehicle 100 (S20). That is, when the charging nozzle unit 52 is connected to the vehicle 100, the sensing unit 60 transmits the operation signal of the charging operation unit 51 to manipulate the hydrogen fuel storage state of each vehicle 100 and the amount of hydrogen fuel charged. The control unit 70, which is transmitted to the control unit 70 and receives various signals, controls the distribution unit 20 and the mixing control unit 40, respectively.

즉, 분배부(20)는 저장탱크부(10)에 저장된 수소연료를 냉각부(30)와 혼합조절부(40)로 분배한다(S40). 이로 인해, 저장탱크부(10)에서 제공되는 수소연료 중 일부는 냉각부(30)에서 냉각된 후 혼합조절부(40)로 이동되고, 저장탱크부(10)에서 제공되는 수소연료 중 나머지는 온도 변화 없이 혼합조절부(40)로 직행한다.That is, the distribution unit 20 distributes the hydrogen fuel stored in the storage tank unit 10 to the cooling unit 30 and the mixing control unit 40 (S40). Accordingly, some of the hydrogen fuel provided from the storage tank 10 is cooled in the cooling unit 30 and then moved to the mixing control unit 40, and the rest of the hydrogen fuel provided from the storage tank 10 is It goes directly to the mixing control part 40 without temperature change.

분배부(20)에서 이동경로가 분배되는 수소연료는 혼합조절부(40)에 도달하고, 혼합조절부(40)는 저장탱크부(10)에서 공급되는 수소연료와, 냉각부(30)에서 공급되는 저온의 수소연료를 혼합하여 수소연료를 설정 온도로 변경한다(S40). 즉, 혼합조절부(40)는 복수개의 충전부(50) 각각에 설정 온도의 수소연료를 공급한다. 보다 구체적으로, 분배부(20)와 냉각부(30)를 통해 공급되는 수소연료는 혼합부(41)에서 혼합되고, 각 차량(100)에 연결되는 충전노즐부(52)에 수소연료를 공급하는 보관부(42)에 구획되어 분배될 수 있다. The hydrogen fuel from which the moving path is distributed in the distribution unit 20 reaches the mixing control unit 40, and the mixing control unit 40 is supplied with the hydrogen fuel supplied from the storage tank unit 10 and the cooling unit 30. The supplied low-temperature hydrogen fuel is mixed to change the hydrogen fuel to a set temperature (S40). That is, the mixing control unit 40 supplies hydrogen fuel with a set temperature to each of the plurality of charging units 50. More specifically, the hydrogen fuel supplied through the distribution unit 20 and the cooling unit 30 is mixed in the mixing unit 41, and the hydrogen fuel is supplied to the charging nozzle unit 52 connected to each vehicle 100. It can be divided and distributed in the storage unit 42.
