Development of the Diagnostic System for Fuel Cell Vehicle Using LabVIEW

摘要

Electric vehicles have long held the promise of zero emission vehicles. A hydrogen-based, fuel cell could provide the power required by an electric vehicle equal to modern gasoline powered vehicle. In this study, the real fuel-cell vehicle system was developing using 500W of proton exchange membrane fuel cell (PEMFC) to power the motor. To measure the performance of the fuel cell system, the operation parameters are necessary to collect. To make a real-time diagnostic system of fuel cell vehicle become more efficient, this study made a monitoring system and Graphical User Interface (GUI). By using GUI, integrated with the hardware (microcontroller, sensors, and communication data) then the data will be easily observed, recorded continuously, and real-time by using developed GUI. Microcontroller that used in this study are National Instruments product LabVIEW and myRIO. myRIO embedded system can obtain the real-time data acquisition of voltage and current as well as data transmission, processing, and monitoring. From observation and data processing performed during the fuel cell vehicles testing using myRIO and GUI, it can be known that from the four measuring points showed almost the same result and the similar tendencies.
