Development of Internet-Based Distributed Test Platform for Fuel Cell Electric Vehicle Powertrain System With Observer

As a new form of test validation, fuel cell and Internet-based distributed test platform has gained increasing attention during the period of dual carbon strategy in China. The reliability of the test platform is an important research direction for the distributed test platform. Under the condition of a large international delay during vehicle powertrain system validation and test, how to predict and optimize the system and how to evaluate the optimization effect becomes a research hotspot. In this paper, on the Internet-based distributed test platform for the fuel cell electric vehicle powertrain system, theoretical and simulation analysis of data transmission and dynamic and economic performance is carried out using observer with large time delay. The analysis found that the observer had an impact on vehicle velocity, fuel cell output power, battery output power and electric motor output torque over the entire test system. In addition, the observer can improve system transparency, which measures the subjective feelings of remote distributed system operators, in the above four indicators and almost has no impact on hydrogen consumption. The results of this study provide a powerful theoretical basis for the optimal design of Internet-based distributed test platforms.
