Problems solved by technology

[0003] In the existing fuel cell test system, the test steps and test execution programs are all executed under the windows system in the industrial computer, but the windows system is a non-real-time system, and the programs executed under the non-real-time system cannot guarantee the real-time performance and performance of the test process. Reliability, so there are lags and time differences in data interaction, logic execution, and fault protection during testing
However, the fuel cell system is a real-time system when running on the vehicle, so the test system designed with a non-real-time system cannot truly restore the environment required for fuel cell system testing, and the data lag and time difference in the non-real-time system will not only affect the test results. Authenticity, but also creates various risks during the testing process

Abstract

The invention relates to a fuel cell test system and method, the fuel cell test system comprises: a lower computer subsystem (10) and an upper computer subsystem (20); the lower computer subsystem (10) comprises: a real-time control module (101), a communication module (102), a calibration module (103) and an input and output module (104); the real-time control module (101) comprises: a real-timeprocessor (1011), a communication interface (1012), a power supply interface (1013) and a control board battery (1014); and the real-time processor (1011) comprises: an ARM core board (10111) and an ARM memory (10112). The upper computer subsystem of the fuel cell test system provided by the invention is only used for generating a configuration file and monitoring test data, while the lower computer subsystem generates a real-time test environment according to the configuration file and performs a real-time test on a fuel cell system to be tested, therefore it can be ensured that data interaction, logic execution and fault protection in the test process are real-time, and the influence of hysteresis and time difference due to the adoption of a non-real-time system by the upper computer subsystem are overcome.

Description

technical field [0001] The invention belongs to the field of battery testing, and in particular relates to a fuel battery testing system and method. Background technique [0002] With the increase of the global demand for energy and the improvement of human requirements for the environment, the research and development of fuel cells in various countries are increasing day by day.
