Material selection and assembly method as well as component design are very important to determine the cost-effectiveness of battery modules and battery packs. Therefore, this work presents Decision Matrix, which can aid in the decision-making process of component materials and assembly methods for a battery module design and a battery pack design.
Through the application of RDM a major technological limitation of battery packs' design is revealed. It is discovered that the mechanical design and the thermal design of battery packs are essentially interrelated; meaning that neglecting either of the two would compromise reliability of the battery pack.
Compactness of packaging design can also have an appreciable influence on thermal performance of a battery pack. Research shows that increasing the cell-to-cell spacing for a battery pack from 1 mm to 10 mm can lead to a loss of approximately 1 °C in the steady state cell core temperature, for all the three physical formats .
