A methodology has been presented that generates and evaluates modular and easy to assemble battery systems in a short period of time that are structurally integrated into the Body in White (BIW) using profile intensive designs. Based upon user requirements regarding electrical and geometrical boundary conditions system topologies for different design spaces are calculated. The user of this methodology is supported by the Design for Automated Battery Assembly tool (DABA) in order to select system concepts that guarantee an easy assembly. The lightweight potential of battery cells, modules and systems can be explored through the use of Design for Lightweighting (DfL), an evaluation tool that combines design methodologies for functional integration within hybrid components. Through the iterative procedure a continuous refinement of the battery system design is possible. The System Structure Design is used to automate the design of a profile intensive structure that supports the battery module topology within the vehicle structure. It is applied subsequent to the design of the battery module topology. Through the use of the methodology it is possible to identify optimal system configurations for specific design spaces, identify optimization potentials regarding module and cell designs and locate bottlenecks within the system assembly. However a refinement of the single parts of the methodology is necessary. In particular an experimental analysis of key assembly steps to consolidate the DABA criteria is necessary.
