Domain based product architecture approach for innovative battery system design

Abstract

Battery engineering faces several challenges in product development process. Due to wide variety of components and functional correlations in a battery system, a novel approach is needed to structure and simplify the product architecture. The aim is to present an abstract product architecture as a tool for further product specific evaluations and developments. State of the art batteries in automotive industry are structured into a breakdown of three levels from battery pack, battery module and battery cell. This publication provides a new approach based on the deficits of consisting product and functional structures to enable a generic method for future battery design approaches. These could be cell-to-x architectures where battery modules might be substituted and their functions are overtaken by other components.
