“…Under the dual pressure of energy crisis and environmental problems, countries all over the world have begun to formulate energy development strategies and develop new and renewable energy sources for the purpose of energy conservation and environmental protection. [1][2][3] The development of electric vehicles (EV) and hybrid electric vehicles (HEV) is considered to be one of the effective measures to alleviate the increasing pressure of environmental and energy crisis. [4][5][6] With the rapid development of electric vehicles, the demand for high energy density power batteries has also grown rapidly.…”

Summary To balance the temperature uniformity and the compactness of the battery module, the heat transfer performance of spray cooling technology is theoretically analyzed in this article. The main factors affecting the heat transfer performance of spray cooling are discussed. Through the experiments, the influence of spray cooling on the thermal management of the battery thermal management system under high discharge rate is studied. The results show that, in spray‐cooling 4 + 2.5 m/s cooling mode, the total heat transfer coefficient K reaches 201.0 W/(m2 K), which is 409.3% higher than the heat transfer coefficient of the forced air cooling. In addition, the difference between the spray concentration of the heat source surface and the spray concentration of the mainstream area during steady‐state heat dissipation is an important factor affecting the heat transfer performance of spray cooling. Moreover, spray cooling can provide a lower temperature rise and a more uniform temperature distribution for the battery module. For the spray‐cooling 4 + 4 m/s case, the maximum temperature rise is only 10.3°C, and the temperature difference among the battery module is stably maintained within 5°C. Therefore, the proposed spray cooling battery thermal management system shows to be efficient approach in handling the heat accumulation of battery module.

“…Secondly, the cooling performance of BTMS was further improved by constructing the structure integrated with hybrid staggered arrangement and longitudinal spoilers. The results respectively revealed that T max and ΔT max were decreased by 13.06 C (25.6%) and 8.45 C (96.35%). Finally, the influences of the length, thickness, and number of spoilers were discussed.…”

“…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.…”

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

“…For example, reasonable structure design could accelerate the heat conduction of the PCM. 16 Adding heat conduction media and flexible skeleton into the PCM could enhance its thermal conductivity and even reduce the contact thermal resistance. 17,18 If multiple methods are used together to dissipate heat from the target, it can be called hybrid cooling.…”
