For lithium-ion batteries (LIBs) used in electric vehicles (EVs), their performance is greatly affected by temperature. To ensure the safety and reliability of EVs, a reliable and efficient battery thermal management system (BTMS) is essential. This paper mainly analyzes air cooling BTMS. First, we propose an air-cooling heat dissipation method for battery modules with herringbone fins and long sleeves, and prove the effectiveness of the program by comparing it with the finless and sleeveless schemes. Second, parametric modeling of the scheme is carried out, the response surface methodology (RSM), radial basis function (RBF), and Kriging surrogate model of the scheme are constructed through design experiments. Then, the Kriging model is determined by the model evaluation index to be well adapted to the problem. We build a multiobjective optimization model (MOOM) and optimize it by multi-objective genetic algorithm (MOGA). Finally, it is found that the maximum temperature (T max ) and the maximum temperature difference (ΔT max ) decrease by 1.5 K and 36.79% without considering the cooling cost. When considering the cooling cost, T max and ΔT max dropped by 0.69 K and 17.92%, respectively. The optimization result improves the heat dissipation effect of the battery module and controls the cooling cost within the required range. Besides, optimization analysis can be carried out according to different actual cost requirements, which provide corresponding guidance for large-scale air-cooling heat dissipation analysis of LIBs.

A balanced structural optimization on the strength of the response surface method is conducted for the battery module with a single-layer sleeved heat spreader plate (SHSP). The module contains 4 Â 5 cylindrical batteries, connected with the SHSP through the tubular sleeve structure. The SHSP structure, simple yet reliable in construction, not only enlarges the heat dissipation area of module but also facilitates temperature uniformity across the batteries through on-plate heat spreading. First, the numerical model is constructed to examine the thermal performance of module. The sensitivity of the structure parameters, including the SHSP thickness, sleeve structure height, caudal length of SHSP, and central distance of batteries, are examined. A balanced optimization is then conducted by varying the structural parameters to obtain the objective functions based on central composite design. Besides the temperature maxima and temperature nonuniformity, the nonthermal metrics such as the pressure differential and the mass of SHSP are also taken as the design objectives to obtain an optimal configuration between performance and energy efficiency. Moreover, the effect of inlet velocity on the module performance is studied. The results indicate that with the optimal SHSP configuration, the temperature nonuniformity of module can be minimized even under lower fan power consumption.

In recent years, with the influence of the current energy shortage and massive environmental pollution, the development of new energy electric vehicles has become a global focus. Lithiumion battery pack is one of the vital components of electric vehicles (EVs). Compared with other types of battery, with the advantages of high energy density, low self-discharge, and long cycle life, lithium-ion battery is extensively used in electric vehicles. [1][2][3][4] However, there is a phenomenon of heat accumulation in the process of the charge and discharge of lithium-ion batteries. The accumulated heat will have a significant impact on the performance and safety of the module of the battery pack, so it is necessary to take appropriate cooling measures. [5,6] Generally, the temperature range that lithium-ion batteries can work effectively is 10-50 C, and the maximum temperature difference of the battery module ought to be controlled within 5 C. To make the battery have a better working environment, the operating temperature of the battery pack ought to be limited between 20 and 40 C. [7,8] Consequently, to ensure it works in a suitable temperature environment, the design of a battery thermal management system is particularly important.At present, the common battery thermal management strategies include liquid cooling, [9,10] air cooling, [11,12] phase change materials (PCM) cooling, [13,14] heat pipe cooling, [15,16] hybrid cooling, [17,18] etc. Compared with other battery thermal management strategies, the air cooling system has been widely used on account of its advantages of lightweight, simple structure, and low cost. [19] However, in the existing air-cooled system, large temperature difference often occurs inside the battery pack. Therefore, for enhancing the heat dissipation performance of air-cooled battery thermal management system (BTMS) and making the temperature distribution of the battery more uniform, scholars have done depth research on the structural design, battery arrangement, adding spoiler, and airflow control.In terms of structural design, Chen et al. [20] researched the symmetrical and asymmetrical air-cooled BTMS system, it was found that the symmetrical system had better heat dissipation performance than the asymmetrical system. And with a small number of batteries in BTMS, the temperature distribution of the batteries was more uniform. Liu et al. [21] proposed a new and original battery thermal management system of J-type, which had one more outlet than the traditional U-type and Z-type BTMS. With different operating conditions, the control valve was used to adjust the opening of the two outlets, which greatly improved the controllability and flexibility of battery thermal management. In terms of battery arrangement, Zhu et al. [22] considered three typical battery arrangements in the same battery module: equal arrangement, increasing arrangement, and decreasing arrangement. Then the study found that the temperature uniformity of the battery module in decreasing
