These sub- systems play a major role in determining the overall electric vehicle performances. In this study, a novel cooling system with fluid in the battery cell is proposed, by which the energy storage system can be optimized through control of the temperature of the batteries. A sensitivity analysis is conducted considering the maximum tempera- ture, the heat rate, the coolant temperature, and the geometry of the cavities. The numerical simulations show that the parameters for the trapezoidal compartment have an impact on the thermal performance of battery. An opti- mal geometry is proposed accordingly. It is concluded that for high values of Reynolds number for which the flow becomes turbulent, a decrease in the battery temperature can be obtained thereby avoiding thermal stresses.

One of these components is a disk or plate that receives heat from a source such as a computer processor. The second component is a set of metal blades that help keep excess heat away from the plate or disc [1]. The last part, and in fact the most vital part of the coolers, is a fan that works by eliminating and dissipating heat around the metal blades and expelling the heat (Like the process you see behind the case of a home computer) [2–5].
