As Today, conventional engines are being replaced by electric vehicles due to environmental concerns and concern about the exhaustion of fossil fuels. Li-ion cells are often used in EV’s because of their high energy density. The thermal behaviour of the batteries is crucial not only for safety operation but also for their capacity and life. This article focusses primarily on the effect of inclusion of conductive material and conditioned air on the battery module. A three-dimensional flow and thermal analysis of an air-cooled module that contains prismatic lithium-ion cells fitted in aluminum structure. The flow and thermal simulation is carried out at the peak discharge of the batteries i.e. 2C rating [17] using a commercial CFD package. The results are compared with the base line model analysis which is performed with same parameters. The temperature is decreased by 7.2oC on average for the addition of fins to the battery module. The increased load on the AC unit is calculated as well when the air is directed to battery module and sufficient modifications for the system are suggested.
