Abstract

For an electric vehicle, the battery pack is the energy storage, and it may be overheated due to its usage and other factors such as surroundings. Cooling for battery pack is needed to overcome this issue and one type is liquid cooling. It has numerous configurations of cooling line layouts and liquid coolants used where the most optimum configuration is preferable to optimize battery cooling which can be utilized by numerous manufacturers to provide the best performing liquid cooled batteries. In this project, the analysis of the effect of liquid coolant and cooling line layout used was done using computational fluid dynamics to determine the optimum liquid coolant and cooling line layout by observing battery temperature, coolant temperature and coolant pressure. The result of this research project is the optimum cooling line layout has the greatest contact area of liquid coolant with the least layout complexity, and the optimum liquid coolant has the greatest thermal conductivity with the least viscosity & density.
