Test method and device for fuel cell power system test platform

Abstract

The invention discloses a test method and device for a fuel cell power system test platform, comprising the steps of: extracting a piece of power consumption data of a hydrogen fuel cell vehicle driving for a long time under actual road conditions, and building a power consumption data model according to an existing test model; Fitting the power consumption data with the power consumption data model to obtain the proportional test duration required by the hydrogen fuel cell vehicle under each test model; build a power system test platform device based on the hydrogen fuel cell electric-electric hybrid power system, etc.; With the method and device provided by the invention, a vehicle power system platform is built in a laboratory environment to simulate the real vehicle use environment as much as possible, and the energy consumption of the system under different energy distribution strategies is tested under the test model, and the equivalent minimum power consumption is obtained. control scheme, so as to screen the optimal energy distribution strategy and optimal control strategy 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 particularly, to a test method and device for a fuel cell power system test platform. 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 automobile 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 of the international automobile industry. [0003] In the prior art, the research on the power system of the hydrogen fuel cell vehicle is generally completed through the test bench or real road test. The test cannot completely simulate th...

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
