Abstract
A hydrogen refueling system includes a first vessel that stores hydrogen generated by a hydrogen generator, a first compressor that compresses the hydrogen generated by the first vessel, a second vessel that stores the hydrogen compressed by the first compressor, a hydrogen supply valve positioned between the first vessel and the second vessel, and a controller that identifies a pressure of the first vessel based on whether a charging target initiates charging and that the first compressor operates, and controls the hydrogen supply valve to supply the hydrogen from the second vessel to the first vessel, based on whether the pressure of the first vessel is less than or equal to set pressure.
