In order to reduce local emissions caused by combustion engines, much effort has been put into developing electric vehicles. In this respect, recent developments show a strong trend towards battery electric vehicles (BEVs). However, as-yet-unresolved disadvantages such as high battery costs and limited driving ranges have prevented customers from buying BEVs. Another potential vehicle concept with zero local emissions are fuel cell electric vehicles (FCEVs) or alternatively, due to their battery which is used as a second power source, better called fuel cell hybrid vehicles (FCHVs). In order to efficiently compare BEVs and FCHVs for different potential deployment scenarios, accurate simulation models are needed. Based on a previously published model for BEVs, this paper presents a longitudinal simulation model for FCHVs. In this context, the focus lies on the power supply for the drivetrain containing the fuel cell (as its main power source), the battery (as a buffer storage), and the operating strategy (managing the power splitting during a load request). In order to enable the parametrization and validation of the simulation model, a particular fuel cell production car, a Hyundai ix35 FC, is extensively examined on a chassis dynamometer and in real driving tests. With this publication we make a large part of the experimental data available on https://mediatum.ub.tum.de (Research Data-Mechanical Engineering).     «
