Problems solved by technology

At present, in the prior art, the proportional valve combined with PID is generally used to control the input of hydrogen to the fuel cell, and the actual flow of hydrogen input to the fuel cell is estimated based on the pressure at the back end of the proportional valve, that is, the pressure at the back end of the proportional valve is continuously fed back to the control controller, so that the controller continuously adjusts the amount of hydrogen input to the fuel cell according to the pressure, so the adjustment time is relatively long

Abstract

The invention relates to the technical field of a fuel cell and discloses a hydrogen injector control method and device, and a storage medium. A power demand signal from a vehicle controller is received, an air flow demand value is determined according to the power demand signal, the air flow of an input fuel cell is controlled according to the air flow demand value, a current air flow value of the input fuel cell is detected, a hydrogen flow demand value is matched in real time based on the current air flow value, a hydrogen injector is controlled for injecting the hydrogen according to the hydrogen flow demand value, in the control process, and the hydrogen injection flow is controlled based on the air flow of the input fuel cell. The method is advantaged in that performing PID control based on the back end pressure feedback of a proportional valve in the prior art is avoided, and the control time is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a control method, a control device and a storage medium of a hydrogen injector. Background technique [0002] The fuel cell system can be applied to automobiles. It is a power generation device that directly converts chemical energy into electrical energy through electrochemical reactions. It uses hydrogen as fuel, and makes hydrogen and oxygen react electrochemically to generate electrical energy. At present, in the prior art, a proportional valve combined with PID control is generally used to control the input of hydrogen to the fuel cell, and the actual flow of hydrogen input to the fuel cell is estimated based on the pressure at the back end of the proportional valve, that is, through continuous feedback of the pressure at the back end of the proportional valve to the control The controller makes the controller continuously adjust the amount of hydrogen input to the fuel c...
