Hydrogen refueling station based on low-temperature high-pressure graded hydrogen storage and hydrogen refueling method thereof

The hydrogen refueling station comprises a liquid hydrogen storage tank, hydrogen storage containers and a hydrogen refueling machine which are sequentially communicated, the hydrogen storage containers are communicated with the hydrogen refueling machine through a main refueling pipeline, the number of the hydrogen storage containers is n, n is larger than or equal to 2, and the main refueling pipeline is provided with a refueling controller; the hydrogen storage container is a low-temperature high-pressure hydrogen storage container, a booster pump and a high-pressure vaporizer are arranged between the liquid hydrogen storage tank and the hydrogen storage container, the temperature value of hydrogen stored in the hydrogen storage container is equal to the highest pressure value, and when n is equal to 2, n is equal to 2; when n is greater than or equal to 3; the filling controller is configured to sequentially control the corresponding hydrogen storage containers to be communicated with the hydrogen adding
