Control method of high-pressure hydrogen storage system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle structure and control, in particular to a control method for a high-pressure hydrogen storage system. Background technique [0002] Due to the complex structure, high risk, and low product maturity, the traditional hydrogen storage system is mostly produced in small batches, and the product reliability is poor. The damage of a single component will cause the failure of the entire system, and the fuel cell cannot operate. In addition, the current hydrogen storage system of fuel cell vehicles, in the event of a collision accident or the damage of a single component in an open area, will cause the failure of the entire system, the vehicle cannot run, and its reliability and ability to face sudden failures are poor. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems mentioned in the background art above, and to provide a control meth...
