Development of Hardware and Software for On-Board Hydrogen Supply System Controller 2019-01-0377

The fuel cell engine is considered to be the ultimate technical direction for the development of vehicle power. The on-board hydrogen supply system is important in fuel cell system. However, the on-board hydrogen supply system is diversified, and the management is mostly integrated in the engine controller. Thus, the fuel cell engine controller is excessive coupled with design of on-board hydrogen supply system. In order to improve the portability and compatibility of the fuel cell engine controller, an independent on-board hydrogen supply system controller is designed. Meanwhile, the hardware and software are developed to control 35 Mpa gaseous hydrogen storage system. After being tested in a high-pressure environment, the controller can detect the temperature, pressure and ambient hydrogen concentration of the hydrogen supply system. Simultaneously, it can drive and control the hydrogen cylinder valve. Besides, the controller can also communicate with the CAN bus of the fuel cell engine through a specific protocol analysis platform software. In addition, it has been verified that the infrared signal waveform, which is emitted by the infrared transmitting module, complies with the software and hardware standards of the hydrogen fuel vehicle supply station. It indicates that the real-time infrared communication between the hydrogen refueling station and the controller are realized. At the same time, the controller can process and report system errors in time. Based on the results, the designed controller has met the needs of the hydrogen supply system applications in the bus fuel cell system, which improves the portability and compatibility of the hydrogen supply system.
