Abstract

The invention provides an automatic test method and system suitable for a vehicle fuel cell. The automatic test method comprises the following steps: S1, acquiring monitoring result information; acquiring state information of a tested fuel cell unit and state information of a fuel cell test unit; S2, confirming that the tested fuel cell unit is in a to-be-tested state, and importing a preset tabulated related test control command and operation parameters after confirming that the fuel cell test unit is in a normal state; S3, the monitoring PC issues an automatic test starting command, all thecontrol commands and the operation parameters operate in sequence, the control commands and the operation parameters determine execution time according to preset control time or preset sensor feedbackparameters, and meanwhile test data are stored; S4, acquiring test result information; S5, when the test unit or the tested unit is abnormal, acquiring automatic fault alarm indication information; according to the method and the system, the interference of manual operation and subjective judgment of testers on the test process and result can be basically eliminated.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to an automatic testing method and system suitable for vehicle fuel cells. Background technique [0002] With the increasingly prominent environmental and energy issues, new energy vehicles are the research hotspots of major automobile manufacturers and R&D institutions in the world. Among them, fuel-cell vehicles (FCV) are known for their high efficiency and near zero emissions It is generally considered to have broad development prospects. In recent years, my country's investment in fuel cells has also continued to increase, and it is an indisputable fact that fuel cell vehicles will occupy an important position in new energy vehicles. The system test of vehicle fuel cell is an important part of the field of fuel cell technology. In the prior art, the accuracy of the test process of the test system in the fuel cell needs to be improved. [0003] Patent document CN104062596A ...
