Experimental Study on Fuel Economy of Fuel Cell Truck Under Different Driving Cycle

Fuel economy is an important indicator to evaluate vehicle performance as it is directly associated with fuel costs. This paper introduces a method to evaluate the fuel economy of fuel cell vehicles (FCVs). A fuel cell truck (FCT) was tested under a 40 km/h constant speed and a China heavy-duty commercial vehicle test cycle-heavy truck (CHTC-HT) driving cycle scenarios to determine the FCV energy consumption, driving range, and hydrogen emissions in different driving cycles and analyze the influences of these driving cycles on fuel economy evaluation. The test results demonstrated that compared with its performance under the 40 km/h constant speed scenario, when the FCT was tested under the CHTC-HT scenario, the electricity consumption per 100 km and the hydrogen consumption per 100 km were increased by 60.35% and 52.02%, respectively; the driving range was reduced by 43.49%; the hydrogen emission per 100 km rose by 171.17%, and the hydrogen emission rate grew by 26.96%.
