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.

“…Therefore, HPs are promising passive systems for BTMS applications. [ 190 ] The amount of PCM used determines its heat storage capacity, the BTMS performance, and the overall weight of the battery pack. The use of PCMs for high‐capacity batteries requires additional space, which is a limited commodity in EVs.…”

“…In order to optimize the battery radiator more efficiently, Chen et al, 15 combined with the resistance flow resistance network model, used the optimization strategy to study the spacing of the battery unit. After the optimization of the battery unit, the temperature can be reduced by up to 4 K. At the same time, scholars have developed a series of optimization methods, for example, multi-objective optimization, 16 artificial neural network (ANN) model, 17,18 topology optimization, 19 machine learning approach, 20 and particle Swarm optimization algorithm. 21 Depending on the heat transfer medium, heat dissipation in batteries is divided into liquid cooling 22 and air cooling.…”

To solve the high heat dissipation problem of lithium ion battery, the air‐cooled heat dissipation with fins is adopted for the thermal management. Heat dissipation characteristics of two types of air inlets and outlets (single air inlet and outlet, and double air inlet and outlet) and two types of surfaces (smooth and fin structure) were simulated and compared. When the air inlet and outlet are single inlet and single outlet, compared with smooth battery packs, finned construction packs can increase the Nusselt number by 24.9%. When the air inlet and outlet are double inlet and double outlet, compared with smooth battery packs, finned construction packs can increase the Nusselt number by 13.3%. The double‐air inlet and outlet battery pack can significantly reduce the average temperature of the battery pack compared with the single‐air inlet and outlet battery pack. Compared with the single‐inlet and single‐outlet solar smooth battery pack, it can increase the Nu by 131.6%, and the comprehensive performance index can reach 1.66.
