Evaluation of powertrain and energy supply systems for rail vehicles

Requirements analyses

Which requirements are relevant for vehicles and vehicle components and what are the resulting requirements for the refuelling and recharging infrastructure? Our analyses range from the component and subsystem level to the overall train level both for rail and freight transport. To do this, we define the areas under consideration and describe the use cases. From these, the requirements are systematically collected, documented in specifications and implemented on a project-specific basis.

Refuelling and recharging infrastructures

Adjustments to the operating programme, the required refuelling and recharging infrastructures and the resulting costs are part of our research portfolio.

To do this, we apply simulation tools and tool chains developed at the DLR.

Optimization of operating strategies and system configurations

We work on the optimization of component operating strategies to reduce energy demand and component ageing. Another focus of the researchers is the investigation of suitable system configurations and strategies for the optimized interaction between on-board energy storage systems and trackside recharging infrastructure.
