Introduction
An optimal design concept of air-cooled battery pack has been proposed. The cooling strategy to improve battery temperature uniformity has been studied. This paper describes a cooling strategy development method for an air cooled battery pack with lithium-ion pouch cells used in a hybrid electric vehicle (HEV).
Below is the flow of a study on battery pack which was used as input for design & selection of the battery pack for a vehicle. To start with the first step is to study the battery pack at the assembly level and generate a detailed Layout/schematic to understand the setup and design philosophy.
Accordingly, a cooling system is typically employed with the battery cells in the battery pack. A typical air cooled battery pack includes single or multiple strings of battery cells, a plurality of spaced apart battery cooling plates, cooling ducts, and control modules.
Here, a multiscale method combining a pseudo-two-dimensional model of individual battery and three-dimensional computational fluid dynamics is employed to describe heat generation and transfer in a battery pack. The effect of battery arrangement on the thermal performance of battery packs is investigated.

battery pack. The sequential order of the individual process steps and the subordinate partial disassembly tasks can vary depending on the system design [13–15]. In most system concepts, such as that of the Audi e-tron 50, the battery pack cover has to first be removed before the electrochemical state of the battery pack can be determined
Adding a part to a vehicle means it must be assembled as well as disassembled which results in a need for a product that is optimal for an assembly-line. A literature study is therefore conducted in this project to improve the understanding of methods including modularisation as well as Design for Assembly and Design for Disassembly.

Abstract. The Li-ion battery operation life is strongly dependent on the operating temperature and the temperature variation that occurs within each individual cell. Liquid-cooling is very effective in removing substantial amounts of heat with relatively low flow rates. On the other hand, air-cooling is simpler, lighter, and easier to maintain. However, for achieving similar …

Saw et al. [43] introduced an air-cooled battery pack with porous aluminum foam wedged between li-ion pouch cells to function as cooling plates as displayed in Fig. 12. A limitation of traditional air cooled BTMSs is that the air medium absorbs heat as it flows along the battery pack leading to the outflow air being hotter than the inflow air which reduces cooling …
