“…However, in the reverse and cross-flow layouts, T max occurs in the middle region of battery pack, and T min . occurs on the side with the greatest number of coolant inlets, which is consistent with the results of Amrut et al, [69] within the maximum temperature difference range of 3.5-5 °C. The temperature distributions of the batteries in the three flow pattern layouts were greatly correlated with theistribution of the AVVF inside the tubes in the corresponding location, which also indicates that the different boiling intensities in each zone of tubes affect the battery temperature characteristics on corresponding zone.…”

In this study, a novel indirect boiling cooling battery thermal management system with two‐phase coolant R141b is proposed for the commercial cylindrical lithium‐ion battery pack. The heat conduction blocks are used to enlarge the heat transfer area between batteries and straight round tubes, and the R141b coolant flows and boils inside tubes to remove heat generated from batteries. Three‐dimensional simulation models are built and used to study the influence of partial structural parameters (height of heat conduction blocks, number and diameter of round tubes), the flow pattern layout, the coolant flow rate, and the battery discharge rate on the cooling performance of BTMS. The results show that the cross‐flow layout significantly improves the temperature uniformity of the batteries, with the maximum temperature difference reduced by 30% compared to the concurrent flow. Meanwhile, the appropriate geometrical parameters can further improve both cooling capacity of the BTMS and the temperature uniformity of the batteries. When the optimized structure with a coolant flow rate of 0.1 L min−1 under the cross‐flow layout, the maximum temperature and maximum temperature difference of batteries discharged at 2C reduced to 38.6 and 3.81°C, which are 97% and 64% of those in the concurrent flow, respectively.This article is protected by copyright.

“…There are many ways in which battery pack cooling can be done, such as liquid cooling, [1][2][3][4] air cooling, [5][6][7] and PCM cooling. [8][9][10][11] The passive cooling system relies on heat transfer by natural convection and radiation.…”

Now-a-days almost all the electric cars are fitted with Lithium-ion batteries due to their self discharge characteristics and high energy density. The major drawback concerning Lithium-ion batteries is that, when a certain temperature is achieved, it could lead to the explosion of the battery. Therefore, Battery Thermal Management System (BTMS) is introduced which helps in the distribution of heat. In this work, a prismatic battery with a mini-channel tube design is used to study the characteristics at different discharge rates and flow rates. The characteristics of the battery are stimulated with ANSYS19.2 tool, at discharge rates of 1-C, 1.5-C, and 2-C with water flow rates of 0.05, 0.5, and 5 LPM. Mesh and time-independent study was performed to validate and find the optimal element size, time step, and the number of iterations. The results obtained indicate a better uniform temperature distribution due to the constructive aluminum mini channels around the lithium-ion battery.
