Test verification rack for passenger car vehicle-mounted fuel cell system

Abstract

The invention provides a test verification rack for a passenger car vehicle-mounted fuel cell system, which belongs to the technical field of fuel cell engines. The technical problem that an existingtest rack of a fuel cell vehicle power system is poor in test working condition and whole vehicle state reduction degree is solved. The test verification rack for the passenger car vehicle-mounted fuel cell system comprises a test verification platform vehicle body framework, an electronic load and a direct-current power supply which is electrically connected with the electronic load, and is characterized in that the fuel cell system is arranged on the test verification platform vehicle body framework through a road surface state simulation system. The fuel cell system is electrically connected with the electronic load, and a vehicle-mounted hydrogen system and a heat dissipation system are arranged on the test verification platform vehicle body framework. The rack has the advantage of high reduction degree of the test working condition and the whole vehicle state.

Description

technical field [0001] The invention belongs to the technical field of fuel cell engines, and relates to a test and verification stand, in particular to a test and verification stand for a fuel cell system mounted on a passenger car. Background technique [0002] A fuel cell system is a power generation device that directly converts chemical energy in externally supplied fuel and oxidant into electrical energy, heat energy, and other reaction products through electrochemical reactions. At this stage, with the rapid development of fuel cell vehicles, especially fuel cell buses, fuel cell systems and fuel cell products continue to increase. At present, the performance, reliability and integration of fuel cell products are difficult to judge, so it is necessary to pass the fuel cell power system testing technology Validation tests are performed on fuel cell products, and existing fuel cell powertrain test benches are not perfect when they are actually built and operated.
