Electric trucks that use fuel cells to generate on-board power are seen as the cornerstone of zero-carbon, zero-emission long-haul heavy-duty transportation. Modularization of fuel cell stacks, components and systems is critical for rapid market entry and lower total cost of ownership. To achieve this, efficient development processes must be utilized to handle the large variety of applications and use cases with reduced engineering effort. The goals can be achieved with model-based development across the entire development chain. This publication presents such a holistic model-based process that extends from the fuel cell powertrain level through the system level to the component level. This process is closely interlinked to the thermal integration, the function development of the hybrid system as well as the fuel cell system of the vehicle via the use of model-in-the-loop approaches.
