Abstract
Thermal management of lithiumion battery modules needs to be an integral part of the design process to guarantee that temperatures remain within a narrow optimal range Also it is important to minimize uneven distribution of temperature throughout a battery module so as to enhance the battery life cycle and charge and discharge performances This paper explores by simulation the benefits of attaching thin surfaces extended into the nearwake of cylindrical lithiumion cells here termed integral wake splitters and of placing flow guidevane in the vicinity of the near wake regarding thermal management When using the integral splitters it is found that the local Nusselt numbers in the very near wake of a single cylindrical cell are depressed and the temperature distribution within the cell was found to be reasonably constant Similar results were found when the cells are in formation Use of guidevanes also show promise in maintaining constant temperature distributions throughout the module
