A dynamic test method for a vehicle fuel cell engine in a powertrain circuit

Abstract

The invention relates to a dynamic testing method of a vehicle fuel cell engine in a power assembly circuit, comprising: S1, establishing a power system model for the vehicle; S2, using the working condition sequence as the input of the model; S3, combining the real-time computer with the fuel The battery engine, electronic load and data acquisition system are connected for data communication, and the electronic load and data acquisition system are respectively connected to the fuel cell engine; S4, arrange the model and working condition sequence in the real-time computer; S5, load the working condition, and run the real-time computer The model in is used to complete the working cycle; S6 is used to evaluate the dynamic performance of the fuel cell engine based on the collected data. Compared with the prior art, the present invention loads the vehicle power system model on the test platform, and forms a closed loop with the actual fuel cell engine system of the measured object through the connection between the sensor and the electronic load, and can realize the acquisition of the fuel cell engine system on the test platform. The purpose of the performance of the engine in the road test.

Description

technical field [0001] The invention relates to a fuel cell engine test method, in particular to a dynamic test method for a vehicle fuel cell engine in a power assembly circuit. Background technique [0002] Because hydrogen fuel cells have a series of excellent performances such as high efficiency, zero emissions, stable operation, and no noise, they are regarded as the most likely power source for future vehicles. Fuel cell hybrid vehicles are the future development trend of the automotive industry. In the process of developing fuel cell vehicles, in order to verify the design of the fuel cell engine system, it is necessary to test the fuel cell engine, the core of the fuel cell vehicle, based on the corresponding standards, so as to develop a fuel cell engine that meets the requirements of the power system . [0003] In terms of the design of fuel cell engine system test platform, there have been many corresponding researches at home and abroad, and a series of results ...
