Dynamic performance testing system for fuel cell automobile power system

Abstract

The invention relates to a dynamic performance testing system for a fuel cell automobile power system. The dynamic performance testing system comprises an environment simulation module, a noise vibration and harshness (NVH) test matching module, an engine hardware-in-loop test matching module for testing, an electric driving system hardware-in-loop test matching module for testing, an automobile power system hardware-in-loop test matching module for testing, an analogue simulation module, a power load parameter observe and control module and a master control management module. The environment simulation module and the NVH test matching module are used for providing actual working conditions. The analogue simulation module is used for simulating operation environment parameters of the actual working conditions under the software environment. The power load parameter observe and control module is used for testing and controlling the power parameters of the engine hardware-in-loop test matching module and load parameters of the electric driving system hardware-in-loop test matching module. The master control management module is connected with the other modules and used for controlling and saving the testing data in real time. Compared with the prior art, the dynamic performance testing system is high in integrity and good in generality, can simulate the actual working conditions, and can comprehensively take the influence of the hot environment and the vibration noise environment on the fuel cell automobile power system into account.

Description

technical field [0001] The invention relates to a vehicle performance testing system, in particular to a dynamic performance testing system for a fuel cell vehicle power system. Background technique [0002] At present, there is no highly integrated special equipment for fuel cell vehicle power system integration, debugging and testing at home and abroad, which cannot meet the tests of fuel cell vehicle power system integration, matching, reliability, durability, environmental adaptability and safety. needs, the specific analysis is as follows: [0003] A. Analysis of domestic and foreign technical status of key instruments and equipment for FC stacks: [0004] At present, there is no test platform for simulating vehicle-mounted variable working conditions of fuel stacks developed for vehicle conditions in China, and only records the actual operating parameters of fuel cells. Many companies in the world have launched their own fuel cell test platforms. Hydrogenics and Nati...

Problems solved by technology

[0019] 1) There is no integrated instrument and equipment at home and abroad that integrates the three systems of fuel cell and auxiliary system hardware-in-the-loop test matching, electric drive system hardware-in-the-loop test matching, and fuel cell vehicle power system hardware in-environment test matching. not tall;

[0020] 2) There is no comprehensive test system at home and abroad that comprehensively considers the dynamic performance of the fuel cell vehicle power system operating under variable working conditions under the matching environment of temperature, humidity and pressure environment and NVH test;

[0021] 3) The domestic fuel cell test system has poor versatility, and the test matching of fuel cell cars and fuel cell buses cannot be considered at the same time;

[0022] 4) Due to the low level of integration, the current domestic and foreign fuel cell test matching system has a single function, and there are few influencing factors for reference
