Work packages (WP)

WP0: Project management

Responsible: Mercedes-Benz AG

Objectives: To support the project partners so that the project objectives are fully achieved within the project duration with the available resources.

WP1: Sustainability

Responsible: iPoint-systems GmbH

Objectives: Development of a sustainability-oriented product development process (NEP) as a generic framework that enables the specification and optimization of the life cycle assessment at the component and overall vehicle level along the product development process. In future, selected sustainability indicators can therefore be used as additional optimization parameters in product development.

WP2: Digital methods and models

Responsible: DYNAmore GmbH

Objectives: The new methods in spatial discretization (advanced classical finite elements and IGA) are intended to improve efficiency, robustness and predictive capability in the respective load case configurations and enable faster and more sustainable CAE design in the future due to reduced simulation effort. The aim is to achieve a level of maturity for the developed methods that will enable them to be used in virtual homologation with predictive capability.

WP3: Digital certification

Responsible: SGS-TÜV Saar GmbH

Objectives: A process methodology for the digital certification of mechanical and ecological legislation is to be developed. The standardized simulation environments, methods and models developed for this purpose can be used in the future in the area of legal homologation, among others, in such a way that a resource-saving virtual certification process can be used.

WP4: Digital complete vehicle

Responsible: Mercedes-Benz AG

Goals: A digital overall vehicle model that includes the HV battery, fuel cell, hydrogen tank and electric axle components while complying with road safety laws and regulations. An ecologically sustainable solution shows the development possibilities for future vehicle models.

WP5: Fuel cell

Responsible: Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW)

Objectives: Development and demonstration of a sustainable fuel cell system with regard to the use of resources, recycling,_{CO2 emissions} and service life. In order to optimize the latter, the operation and ageing of the cells used are modelled and tested experimentally. The data will be used to draw conclusions about optimized operational management in terms of efficiency and service life.

WP6: Hydrogen refueling system

Responsible: Hexagon Purus GmbH

Objectives: Development of a new tank design for 700 bar H2 _flat storage tanks and system weight reduction by means of linerless tanks and secondary lightweight construction with regard to force transmission and integration into the vehicle structure. Development of sustainable and economical material and manufacturing concepts for tank and liner technologies as well as the digital representation of the tank system in the form of validated tank component models.

AP7: HV battery system

Responsible: BMW AG

Objectives: Holistic development, implementation and validation of innovative HV battery systems based on existing systems, taking into account mechanical, thermal and electrical behavior as well as selected sustainability indicators.

AP8: Electric axis

Responsible: ZF Friedrichshafen AG

Objectives: Development of axially scalable physically and virtually validated electric axles and improvement of the ecological balance through consistent lightweight construction, structural improvements and the use of a new mix of materials for subsystem architectures, rotor shafts and hybrid lightweight housing components.

WP9: Technology carrier

Responsible: EDAG Engineering GmbH

Objectives: Prototype approval of the vehicle, which allows approved test drivers to test defined driving maneuvers on public roads. The aim is also to test charging and refueling scenarios close to the customer. The data collected during the basic application and testing will be used to validate and optimize the model

WP10: Knowledge transfer and dissemination

Responsible: ARENA2036 e.V.

Objectives: To ensure that the results and tools generated are also utilized outside of the consortium and to facilitate an interdisciplinary scientific exchange. At the same time, this work package forms the interface to society in order to sensitize the general public to technological developments in terms of sustainability.
