Modelling %26 Analysis of a Fuel Cell Hybrid Electric Vehicle using Real-World %26 Standard Driving Conditions

Abstract

This paper presents an acausal model-based system-level simulation of a fuel cell plug-in hybrid electric vehicle (FCPHEV) (also known as the H2EV) in Dymola. The modelling part includes the development of a full vehicle and its subcomponents. The simulation (analysis) part involves investigation of the vehicle performance, fuel economy (Wh/km or gH2/km) and carbon footprint (Cf) using both standard & real-world (UK) and homologation (Japan) driving conditions. The effect of the addition of auxiliary load on vehicle range is also explored based on these two countries in conjunction with corresponding drive cycles. Comparing to a commercial FCEV, the well-to-wheel (WTW) analysis results show that by adopting the proposed H2EV during Japan Olympics 2020, Cf can be reduced and fuel economy improved with an assumption that Japan produces hydrogen fuel from renewable energy resources only.
