HYDROGEN FILLING DEVICE AND HYDROGEN FILLING METHOD

Japanese Patent JP2017207094

A

PROBLEM TO BE SOLVED: To provide a hydrogen filling device and a hydrogen filling method in which a measurement of pressure at the time of finishing hydrogen gas filling can be carried out and at the same time an error of a measured value from the hydrogen gas filling finish time to the hydrogen gas diffusion finish time can be reduced.SOLUTION: There are provided a hydrogen gas supply passage 12 for supplying hydrogen gas to a container that becomes an object to which hydrogen gas is supplied; a first opening or closing valve 24 arranged at the hydrogen gas supply passage 12; a hydrogen gas diffusion passage 15 branched at a secondary side of the first opening or closing valve 24 at the hydrogen gas supply passage 12; a second opening or closing valve 29 arranged at the hydrogen gas diffusion passage 15; a first pressure gauge 26 and a second pressure gauge 27 arranged at the secondary side of the first opening or closing valve 24 at the hydrogen gas supply passage 12. The first pressure gauge 26 can measure up to the maximum supply pressure of hydrogen gas and the second pressure gauge 27 selects a hydrogen filling device 1 showing a higher accuracy than that of the first pressure gauge 26.SELECTED DRAWING: Figure 1
