Similar to the cooling plate, the region cooled closest to the outlet would also have the worst cooling performance as the liquid coolant would absorb most of the battery pack’s heat at that point. Hence, a larger number of parallel tubes are preferred over a serpentine configuration.
With prismatic and pouch cells, the utilization of cooling plates allows a greater area of the battery pack to be cooled. Notably, the weight of the aluminum or copper cooling plate would dramatically increase the weight of the EV due to the large surface area of the battery pack that has to be cooled.
The battery used in the model is a li-ion battery with a length of 65 mm, width of 18 mm and a height of 140 mm as displayed in Fig. 8 (b). The heat generation model of the li-ion battery is based on discharge rates between 0.5C to 2.5C with 0.5C increments while the air inlet velocity was set at 3.0 m/s and 3.5 m/s to ensure results accuracy.
Electric vehicle battery cooling plates mounted on battery modules bring cooled liquid near the module. The working fluid absorbs heat conducted into the cold plate from the module as it passes through. Heat is carried in the pumped liquid away from the battery pack for dissipation with a heat exchanger or radiator.
The author examined the cooling system when utilizing two different cooling materials, at first the system was designed using copper foam filled with paraffin, whereas the other one only contained a commercial PCM, RT 25HC from Rubitherm, with a melting point of 25 °C.
Most cooling methods are only able to cool the cell at the surface level as cooling the li-ion cell from the core would involve altering the composition of the cell itself which in turn would reduce the compactness and efficiency of the battery.

This article by Srinivas Burla, Project Manager (Battery and Powertrain) at PURE EV, discusses the types of battery thermal management systems and the advantages of using phase change materials for battery cooling.
A phase change material used as a thermal storage unit is made up of a material (e.g., wax) within a metal housing with a heat source attached so that, as the source conducts heat to the enclosure, the phase change material within absorbs the energy as it changes phase (usually from solid to liquid). Then, as the heat source energy output reduces, the phase …
