Hardware-in-the-loop fuel cell simulation test equipment and method

Abstract

The invention discloses hardware-in-the-loop fuel cell simulation test equipment and a hardware-in-the-loop fuel cell simulation test scheme. The technical scheme is that the equipment comprises a gas supply pipeline, a fuel cell, a cell simulator, a load box and a computer which are sequentially connected, wherein the gas supply pipeline comprises a hydrogen pipeline and an oxygen pipeline. The method comprises the following steps: (1) determining charging and discharging characteristics of a battery simulator through a preset battery model; (2) enabling the fuel cell system to provide source power by simulating an actual power consumption state through the load box; (3) creating a power supply model in which the fuel cell charges the battery and the battery supplies power to the load box; (4) verifying and recording the reliability of the FCU and the BMS according to the continuous change of the power consumption of the terminal. According to the scheme provided by the invention, the scene simulation carried by the fuel cell discharge model is realized through the establishment of the system, so that the research, development and verification of a fuel cell controller (FCU) and a battery controller (BMS) in a fuel cell power generation system are realized earlier in a development link.
