The project is focused on the research of validation methods and validation environments for the development of electric drive concepts such as fuel cell vehicles and is oriented towards the following question: How much battery does the fuel cell need for a planned application and how do adapted simulation, validation and test methods for components and systems of electromobility look like? To this end, existing approaches for the validation and development of electrified drives will be transferred to fuel cell drives and, in cooperation with the chinese partner, a system up to hardware demonstrator realisation in the vehicle will be implemented. The design takes the different boundary conditions of the two markets in Germany and China into account. The result of this project is a methodical framework (operation system) for resource-efficient and knowledge-based planning, control and derivation of spatially distributed, mixed virtual-physical validation activities depending on maturity, test case and validation objective. This should support the early, efficient and continuous evaluation of a sufficient validity of the hybridisation concepts of H2 fuel cell vehicles under the market-specific boundary conditions.
