Abstract
Optimal component sizing and hybridization play vital task in reducing fuel utilization, increasing fuel cell system longevity and fuel economy of fuel cell electric vehicles. This paper proposes a fuel cell-battery powered vehicle is modeled and analyzed in MATLAB/Simulink tool known as Advanced Vehicle Simulator (ADVISOR). In addition to the optimal component sizing of power source components, the new World harmonized Light Vehicle Test Cycle (WLTC) is introduced and embedded into the ADVISOR software to estimate the driving behavior of the proposed fuel cell electric vehicle (FCEV). Approximately 10.5 % more gradeability performance achieved for the proposed powertrain against benchmark fuel cell powered vehicle Moreover, the world light-duty test cycle exhibit 18.5 % more fuel cell cut–off time and 29 % less run on time when compared with new european driving cycle (NEDC) cycle. The results of this study showed better fuel cell energy efficiency in terms of Wh/mile, fuel cell on–off strategy, cold start ability, acceleration and gradeability performance over the world light-duty test cycle drive cycle against new european driving cycle.
