Battery electric vehicles that would be suitable for urban traffic as well as for longer distances will be equipped with a range extender (REX). In this range extender vehicle concept, the powertrain is driven mainly by the high performance li-ion battery added by a HT-PEFC (Polymer Electrolyte Membrane Fuel Cell). The on-board fuel cell range extender serves as an additional energy source, which charges the high performance battery during the trip especially in a long distance trip. On the basis of existing system models, such as fuel cell and battery, a complete vehicle model is been developed with the help of the AlternativeVehicles library [1], especially the thermal model has been extended and parameterized. For the thermal coupling between the high-temperature fuel cell and the hydrogen storage, a high temperature cooling circuit is modeled. The battery temperature control is represented in the model by means of a low-temperature cooling circuit. Considered the challenges that are now placed on modern cars, several scenarios such as cold start and warm-up phase are been created. For these scenarios, suitable operating strategies can be developed and integrated into the overall vehicle model. Based on various driving cycles, the thermal and electrical behavior of the overall system is investigated.
