Abstract
In the development of alternatively powered rail vehicles, determining the appropriate sizes for fuel cells and batteries poses significant risks and challenges for manufacturers and operators. This study focuses on establishing a standardized approach for sizing components of alternative drivetrains within a modular energy system. The objective thereby is to increase production volume, lower costs, and streamline the customization of energy systems for optimized usage.
To define these component sizes, an analysis of German regional rail transport routes was conducted. Based on this analysis, battery and fuel cell powered drivetrains were automatically designed using a simplified operational strategy. Subsequently, the calculated sizes of batteries and fuel cells were statistically analysed. The obtained results were compared with existing initiatives for modular fuel cell and battery component sizes. Based on this a Modular Power Pack was concluded, which should serve the suitability for future rail application.
