Abstract

Battery is one of a very important element for electric vehicle. Battery thermal management should be emphasized to ensure the use of extended batteries and to avoid the catastrophic destruction .To identify the behaviour of the heat flow that occur on the battery, analysis of thermal convection flow had been made along the heat sink at batteries . Convection is a mode of heat transfer which includes the movement of the molecules of the material. The fluid motion enhance the heat transfer, since it brings wanner and cooler chunks of fluid into contact, initiating higher rates of conduction at a greater number of sites in a fluid. The application software of Computational Fluid Dynamic (CFD) had been used to show the graphical heat distribution along the flow of air that passes the battery duct. In addition, this study also examines the relationship between vehicle speeds with the rate of heat transfer by using existing data. The result shows the changes of heat for air from inlet to outlet flow for the heat sink batteries. The value of heat transfer is positive means that the heat from the batteries had distributes along the air flow. To find out whether computerized analysis is wrong or not, confirmation had been made by comparing the data with the data from theoretical calculation. Validation results show only slight differences between the data of both analysis and can be assuming that the analysis is valid.
