Fuel cell power system test platform test method and device

Abstract

The invention discloses a fuel cell power system test platform test method and device. The method comprises steps of extracting electric energy consumption data of a hydrogen fuel cell vehicle runningfor a long time under an actual road condition, and building an electric energy consumption data model according to an existing test model; carrying out data fitting of the electric energy consumption data and the electric energy consumption data model to obtain equal-proportion test duration required by a hydrogen fuel cell vehicle under each test model; building a power system test platform device and the like based on the hydrogen fuel cell electric-electric hybrid power system. The method is advantaged in that a whole vehicle power system platform is built in a laboratory environment as much as possible to simulate a real vehicle use environment, statistics of system energy consumption conditions under different energy distribution strategies tested under a test model is performed, anequivalent minimum power consumption control scheme is obtained, so an optimal energy distribution strategy and an optimal control strategy are screened in the laboratory environment.

Description

technical field [0001] The invention relates to the technical field of performance testing of a hydrogen fuel cell electric-electric hybrid power system, and more specifically relates to a test method and device for a test platform of a fuel cell power system. Background technique [0002] At present, although many research results have been achieved in the field of hydrogen fuel cells at home and abroad, the commercial operation of the hydrogen fuel cell vehicle industry is still in its infancy, and many technical problems need to be solved. In particular, my country's auto industry has a shallow foundation and a weak foundation. As the development direction of new energy technology, hydrogen fuel cell vehicles can achieve overtaking in corners in the international auto industry. [0003] In the prior art, the research on the power system of hydrogen fuel cell vehicles is generally completed through test benches or real road tests. The tests cannot completely simulate the l...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the research on the power system of hydrogen fuel cell vehicles is generally completed through test benches or real road tests. The test cannot completely simulate the long-term operation of hydrogen fuel vehicles on various road conditions, and cannot be systematically considered. Energy consumption of the vehicle for a long time

[0004] It can be seen from the above description that there are certain test defects in the test method for hydrogen fuel cell vehicle power system in the prior art
