The cooling system is capable of providing the required cooling for the battery pack. It is important that the temperature difference between the top and bottom surfaces of the batteries within the module is less than or equal to 5 °C. The cooling plate must be maintained at a temperature less than or equal to 30 °C.
Gel batteries are a type of rechargeable battery that uses an electrolyte in gel form instead of liquid. This gel is composed of sulfuric acid, water and silica, and is thicker than the liquid electrolyte used in conventional lead-acid batteries. The gel acts as a medium to transport electrical charges between the battery's electrodes.
Zhoujian et al. studied a battery thermal management system with direct liquid cooling using NOVEC 7000 coolant. The proposed cooling system provides outstanding thermal management efficiency for battery, with further maximum temperature of the battery’s surface, reducing as the flow rate of coolant increases.
Wu et al. immersed Li-ion batteries in silicone oil, which is flowing, to improve safety and performance. Direct liquid cooling has the mass and volume integration ratio of the battery pack as high as 91% and 72%, respectively; 1.1 and 1.5 times that of indirect liquid cooling with the same envelope space.
Therefore, despite significant research being conducted on phase change material cooling, the question arises as to its practical feasibility for commercial battery thermal management systems. To find a solution to this question, increasing research has been reported on direct liquid cooling for battery thermal management. 4.2.
Anisha et al. analyzed liquid cooling methods, namely direct/immersive liquid cooling and indirect liquid cooling, to improve the efficiency of battery thermal management systems in EVs.
