Abstract: As a clean energy, hydrogen energy has become an important choice for countries around the world to solve energy and environmental problems. Among them, the efficiency of hydrogen storage in terminal equipment has become the key to whether hydrogen energy can be used on a large scale in the transportation and energy fields. Aiming at the low-temperature and high-pressure composite test environment required for the research of Cryo-compressed hydrogen storage technology, a Cryo-compressed test system was designed and developed. The type III hydrogen storage bottle has carried out pressurization, pressure retention and pressure relief tests under cryogenic conditions, and realizes remote data transmission and process control through the cabin data interface to ensure the safety of the test process. The results show that the test system can achieve rapid temperature drop and pressure increase, forming a Cryo-compressed composite environment of 20MPa/80K-100K, while maintaining stable pressure and releasing pressure quickly and safely. It can not only be used for performance testing of cryogenic composite materials, but also meet the demand for pressure and temperature cycle fatigue testing in the development of hydrogen energy equipment. It helps the development and testing of key equipment for automotive cryogenic systems, and can also provide a reference for the research of related test systems.
