On road evaluation of three Hyundai ix35 Fuel Cell Electric Vehicles

摘要

In order to get an improved insight into the capabilities of fuel cell powered vehicles, three Hyundai ix35 vehicles were monitored during 1.5 years and a large number of variables were logged during more than 1500 trips, totalling more than 40.000 km. This paper presents the data collection procedure, data storage methods and some of the measurement results. Single trip data shows the use of the fuel cell stack and its cooling system. Purging loss for the trip is analysed. Aggregated results for all trips not only cover fuel consumption and electric energy use, but also the internal resistance values for fuel cell stack and high power battery. The fraction of time that the stack is used above a given power level is shown, as well as the average stack power per vchicle. The average electric fuel efficiency for the three vehicles is presented and a comparison is made with state of the art battery electric vehicles. The data presented may be valuable for modelling purposes. The paper closes by discussing the implications of the findings, drawing some conclusions and presenting an outlook for further work.
