Problems solved by technology

And only the impact of a change in a certain component under test on the entire fuel cell system can be obtained. When optimizing system energy consumption and improving energy efficiency, there are many repetitive tasks, long rectification cycle, and high risk of project delay
Since the components are tested individually, it is impossible to monitor the energy flow changes of the fuel cell system

Abstract

The invention provides an energy flow test system for a hydrogen fuel cell system, which can perform system-level energy flow test. By synchronously collecting and recording real-time data of the cooling system, the air system and the hydrogen system and sending the data to the upper computer, multiple times of part-level energy flow testing can be reduced. According to the data collected and processed by the upper computer, the energy flow of the hydrogen fuel cell system is monitored, data support is provided for model selection, energy consumption optimization, efficiency improvement and cost reduction of all parts, and the project or rectification period can be greatly shortened.

Description

technical field [0001] The invention belongs to the field of fuel cell testing, in particular to an energy flow testing system for a hydrogen fuel cell system. Background technique [0002] Currently, hydrogen fuel cell energy flow tests are mostly at the component level. For example, individual monitoring of energy consumption of air compressors, expanders, and water pumps cannot reflect the energy flow and distribution of the entire hydrogen fuel cell engine system. Therefore, in the development of energy management and energy consumption optimization of hydrogen fuel cell engine, it is impossible to accurately consider the influence of interaction between various subsystems on the energy consumption of fuel cell engine system. [0003] The prior art mainly uses corresponding sensors to separately collect the energy consumption and energy efficiency of a certain component of interest during system testing. And only the impact of the change of a certain tested component on...
