This analytical work was performed to reveal the effect of inlet geometry of battery pack on the temperature distributions and flow stream line for a electric vehicle. To achieve this, standard k-ε model with wall function was applied and the working conditions of battery pack under different air flow rate and inlet area according to the geometry were estimated. It was revealed that as inlet area was smaller, the flow velocity was faster, and it can't cover the whole area of battery module. In case of two inlet case, the cooling efficiency of air flow is less than that of one inlet case because of low flow rate.
