Abstract

In this study, a battery pack is under consideration for its thermal management because during operational conditions, heat is produced as a byproduct, and if not removed, the heat will damage the battery pack. That is why, we have used CFD simulations for this task. The battery cells are exposed to air in an inlet and outlet arrangement. Variable inlet velocity conditions have been employed to analyze its impact on the heat swept. The operating parameters is the inlet velocity for a fixed heat generation rate of 4,20,000 W/m³ in the battery cells, while the target parameters are the heat transfer coefficient, battery temperature and the inlet pressure. The flow model is the 3D- Navier-Stokes equations along with the Standard k-ϵ turbulence model. The simulations are conducted on ANSYS Workbench, while the solver is Fluent.
