A systematic comparison of the packing density of battery cell-to-pack concepts at different degrees of implementation

Abstract

This microarticle shows the potential of battery cell-to-pack design approaches by means of a systematic investigation at different depths of implementation. For this purpose, battery concepts are created under cell-to-pack aspects based on a conventional concept and investigated with regard to the geometric layout and the packaging density at pack level. Implementation options range from simply omitting the module housing while keeping the subdivision of the original modules up to a pure block design. For the studies, an object-oriented tool was developed that models the components of battery systems as class objects and provides various functions for calculating parameters and generating graphics for layout visualization.
