Abstract

The invention discloses a hydrogen filling control method and system. The method comprises the steps that the temperature and pressure in a to-be-hydrogenated hydrogen storage tank are detected in real time; a gas inlet valve of the to-be-hydrogenated hydrogen storage tank is opened, and the hydrogenation rate of hydrogen input into the to-be-hydrogenated hydrogen storage tank is controlled to be increased to the preset highest rate; when the fact that the hydrogenation rate reaches the preset highest rate is detected, the hydrogenation rate is controlled to be reduced to a preset stable rate; when the fact that the hydrogenation rate reaches the preset stable rate is detected, the hydrogenation rate is controlled to be kept at the preset stable rate; and when the pressure in the tank reaches the target hydrogen filling pressure, the gas inlet valve is closed. On the basis of ensuring that the pressure and the temperature of the hydrogen storage tank in the hydrogenation process do not exceed safety threshold values, the hydrogenation rate can be effectively increased, and the hydrogen filling time can be effectively shortened, so that the purpose of rapid, safe and low-cost hydrogenation can be achieved.

Description

technical field [0001] The invention relates to the technical field of high-pressure hydrogen storage, in particular to a hydrogen filling control method and system. Background technique [0002] Hydrogen energy is recognized as one of the most promising secondary energy sources due to its outstanding advantages such as cleanliness, environmental protection, and large-scale storage and transportation. At present, most hydrogen refueling stations use high-pressure hydrogen for hydrogenation and storage. The hydrogen filling process is a process in which the temperature and pressure in the hydrogen storage tank increase sharply. It is generally recognized internationally that the safety limit during the hydrogen filling process is the The temperature cannot exceed 85°C and the pressure in the tank cannot exceed 87.5MPa. Once this safety limit is exceeded, there will be leakage or explosion, and the result will be disastrous. [0003] In order to solve the safety control of te...
