Embodiment

[0022] An industrial computer is used as the hardware platform, 16-channel analog-to-digital A / D acquisition card, 16-channel digital-to-analog D / A acquisition card and 32-channel digital I / O board are used as hardware support. The software development platform is Visual C++.

[0023] The fuel cell simulation model of the present invention mainly includes an air supply system, a hydrogen supply system, a cooling water system and a fuel cell stack ( figure 1 ). The fuel cell generates DC power through the electrochemical reaction of hydrogen and oxygen. A pure fuel cell reactor cannot be used directly as a power source. It requires the cooperation of various subsystems and controllers of the fuel cell stack to output power safely and stably: hydrogen supply The system is responsible for continuously providing high-purity hydrogen with a certain pressure and a certain flow rate to the fuel cell stack to ensure the continuous progress of the electrochemical reaction in the fuel ...

Abstract

The invention relates to a fuel cell semi-physical simulation testing system based on VC and a building method. The system comprises an industrial control computer, a 16-path analog-to-digital (A/D) collecting card, a 16-path digital-to-analogy (D/A) collecting card and a 32-path digital I/O board. A VC software development model is used for replacing dynamic operation conditions of a practical air supply system, a hydrogen supply system, a cooling water system and modules of a fuel cell stack. By means of the A/D collecting card, the D/A collecting card and the digital I/O board, relation between a fuel cell stack controller and a simulation model is built, and a whole fuel cell testing system is simulated. Model input and output parameters are transmitted to the fuel cell controller through the A/D collecting card, the D/A collecting card and digital I/O board, an actual controller, various signal conversion boards and the simulation model used for replacing a true fuel cell form a closed loop testing system.

Description

technical field [0001] The invention belongs to the field of electric vehicle testing and testing, in particular to a VC (Visual C++)-based fuel cell semi-physical simulation testing system and an establishment method. Background technique [0002] Fuel cells, especially proton exchange membrane fuel cells, have good performances such as low noise, no pollution, high energy conversion efficiency and low operating temperature, and are especially suitable as power sources for electric vehicles. Governments, enterprises and scientific research institutions of various countries are focusing on the research of proton exchange membrane fuel cell electric vehicles, and the fuel cell system, as the heart of fuel cell electric vehicles, is currently in a new breakthrough period and is becoming a new research and development hotspot. [0003] A large number of tests are required during the development of fuel cell controllers, especially in dynamic environments. At present, the stati...
