Work packages (WP)

WP0: Project management

Responsible: Mercedes-Benz AG

Objective: 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 concretization and optimization of the LCA at the component and overall vehicle level along the product development process. Thus, selected sustainability indicators can be used as additional optimization variables in product development in the future.

WP2: Digital methods and models

Responsible: DYNAmore GmbH

Objectives: The new methods in spatial discretization (further developed classical finite elements and IGA) are intended to improve efficiency, robustness and predictive capability in the respective load case configurations and to enable a faster and more sustainable CAE design in the future due to lower simulation efforts. For the developed methods, a level of maturity is to be reached that enables a prognosis-capable application in virtual homologation.

WP3: Digital certification

Responsible: SGS-TÜV Saar GmbH

Objectives: A procedural 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 other things, in such a way that a resource-saving virtual certification process can be used.

WP4: Digital complete vehicle

Responsible: Mercedes-Benz AG

Objectives: A digital complete 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 system

Responsible: Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW)

Objectives: Development and demonstration of a sustainable fuel cell system with regard to resource use, recycling, CO2 emissions and service life. To optimize the latter, the operation and aging of the cells used will be modeled and tested experimentally. The data will be used to draw conclusions on optimized operation with regard to efficiency and service life.

WP6: Hydrogen tank system

Responsible: Hexagon Purus GmbH

Objectives: Development of a new tank design for 700 bar H2 flat storage and system weight savings 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.

WP7: 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.

WP8: Electric axis

Responsible: ZF Friedrichshafen AG

Objectives: Development of axially scalable physically and virtually validated electric axes as well as improvement of the life cycle assessment through consistent lightweight construction, structural improvements and use of novel material mix in subsystem architectures, rotor shafts and hybrid lightweight housing components.

WP9: Technology carrier

Responsible: EDAG Engineering GmbH

Objectives: Prototype approval of a vehicle that allows approved test drivers to test defined driving maneuvers on public roads. In addition, the aim is to test charging and refueling scenarios close to the market. 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 the utilization of the generated results and tools also beyond the consortium and to enable the 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 the sense of sustainability.
