The invention relates to the technical field of
new energy automobile structures and control, in particular to a control method of a high-pressure
hydrogen storage
system. The method comprises the steps: controlling the
hydrogen storage
system comprising a plurality of
hydrogen supply paths, collecting the in-
bottle pressure change value of a high-pressure
hydrogen storage bottle at a pipeline inlet in each
hydrogen supply path and the pipeline pressure change value of each
hydrogen supply path, and comparing the collected in-
bottle pressure change value and pipeline pressure change value witha pressure
limit value; judging whether the
hydrogen supply paths break down or not: if yes, controlling an
electromagnetic valve at the outlet of the fault hydrogen supply path to close the hydrogensupply path, and if not, opening the
electromagnetic valve at the outlet of each hydrogen supply path to enable the high-pressure
hydrogen storage bottle of each hydrogen supply path to supply hydrogen to a galvanic
pile. The control method is extremely simple and efficient, whether the hydrogen supply path is opened or not is selected according to the fault condition of each hydrogen supply path, the whole method can cope with various fault conditions, and efficient and safe hydrogen supply of the galvanic
pile is ensured.
