  • Publication number: 20240288124
    Abstract: In a high pressure gas charging system and method, the system includes a charging container, a fluid supply part and a high pressure charging part. A high pressure gas is charged in the charging container. The fluid supply part is connected to a first side of the charging container, and is configured to supply incompressible fluid into the charging container before charging the high pressure gas. The high pressure charging part is connected to a second side of the charging container, and is configured to charge the high pressure gas into the charging container in which the incompressible fluid is already supplied. The incompressible fluid is supplied to the charging container until an inner pressure of the charging container reaches a predetermined pressure, and the incompressible fluid is removed to outside through the fluid supply part as the high pressure gas is charged into the charging container.
