Abstract

The invention provides a hydrogen gas storage bottle opening control method for a fuel cell hydrogen system. The hydrogen gas storage bottle opening control method comprises multiple steps: obtaininga state when the fuel cell hydrogen system stops last time; judging whether the state when the fuel cell hydrogen system stops last time is a normal stop state or not, and obtaining a hydrogen gas pressure value in each hydrogen gas storage bottle in the fuel cell hydrogen system if the state when the fuel cell hydrogen system stops last time is judged to be normal stop state; and sequentially opening hydrogen gas storage bottles in the hydrogen system in sequence according to the sequence that the hydrogen gas pressure value is from low to high. The method has the advantages that pressure impact, on the hydrogen system, of hydrogen bottle pressure every time the hydrogen system starts is reduced, and the service life of the hydrogen system is prolonged.

Description

technical field [0001] The invention relates to a control method, in particular to a method for controlling the opening of a hydrogen storage cylinder of a fuel cell hydrogen system. Background technique [0002] Hydrogen fuel cell vehicle technology is becoming more and more mature. As a new energy vehicle with zero pollution and zero emissions, hydrogen fuel cell vehicles have increasingly entered the transportation system and have been widely recognized by the public. Fuel cell vehicles use hydrogen as fuel, and through the fuel engine, chemical energy is efficiently converted into electrical energy to drive the vehicle. The whole process only discharges pure water, so it is the most ideal energy-saving, environmentally friendly and zero-emission vehicle to replace traditional fossil fuel vehicles in the near future Transportation. [0003] The hydrogen system of a hydrogen fuel cell generally includes multiple hydrogen bottles for storing hydrogen. The hydrogen system a...
