Beschreibung

'The battery system design is a cross-sectional issue that relates to natural sciences as well as engineering. This collaboration between various fields of research and the number of components defining the battery system can lead to difficulties during the development process. State of the art methodological approaches for electric vehicle battery systems can be used during the conceptual phase of the development process to shorten development time. This automation could be for example CAD-based in order to process the geometrical or mass specific characteristics of the components of a battery system. A major drawback of this approach is to leave out requirements of the following manufacturing and assembly processes. The approach described within this paper is associated with the methodology of simultaneous engineering as well as design for assembly. The objective is to shrink the overall development and manufacturing time of a battery system through parallelization of engineering design (i.e. the conceptual development of the battery system) and manufacturing (i.e. the assembly process design).To solve the problem of parallelization, this work focuses upon the analyses of assembly process characteristics. In addition to these the boundary conditions referring to the battery system design are taken into account. These two sets of boundary conditions are processed in a software-based tool in order to give recommendations for the battery system design and/ or the assembly line design. A starting point for this approach is done by an analysis of the battery system. This is done by splitting it into three (sub-) systems which are at the cell, module and system levels. The next step after the completion of the requirement analysis for battery systems will be the analyses of existing assembly strategies, handling and gripping technologies and the connection of derived parameters via mathematical functions.'
