Dynamic test method of vehicle fuel cell engine in power assembly loop

Abstract

The invention relates to a dynamic test method of a vehicle fuel cell engine in a power assembly loop. The method comprises the following steps: S1) establishing a power system model for a vehicle; S2) serving a working condition sequence as input of the model; S3) enabling a real-time computer to be in data communication connection with a fuel cell engine, an electronic load and a data acquisition system, and enabling the electronic load and the data acquisition system to be connected with the fuel cell engine; S4) arranging the model and the working condition sequence in the real-time computer; S5) loading the working condition sequence, operating the model in the real-time computer and finishing working condition circulation; and S6) according to the collected data, estimating dynamic performance of the fuel cell engine. Compared with the prior art, by loading the overall power system model to a test platform, and through connection between a sensor and the electronic load, a closedloop is formed with a measured object fuel cell engine system object, and the purpose of obtaining the performance of the fuel cell engine in road test on the test stand can be realized.

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 ...
