Abstract:

Electric vehicles (EVs) include battery electric vehicles (BEVs), fuel-cell vehicles (FCVs) and fuel-cell hybrid electric vehicles (FCHEVs). BEVs and FCEVs have many different modeling methods, depending on the purposes of simulation and degree of accuracy. The performance of vehicles is usually evaluated using standardized driving cycle tests; however, the results from standardized driving cycle tests deviate from the real-world driving cycle. In this paper, the authors mainly use reverse simulation to calculate FCVs and BEVs.  In order to test the adaptability of EVs to real-world driving cycles, conditions of three typical routes in Tianjin are collected and their characteristics analyzed; then BEV and FCV models are created based on a type of FCHEV to simulate 0–100 km/h acceleration and cruising performance under a real-world driving cycle; finally, a motor bench is used to test the performance of FCHEV under the NEDC (New European Driving Cycle). Following a comparison of the three models' adaptability to a real-world driving cycle based on simulation and test results, it was discovered that FCHEV can recycle braking energy and has a quick dynamic response, making it well suited to a real-world driving cycle.
