摘要：

选择以某型集装箱储能系统电池单元模块为研究对象，基于CFD仿真技术对其热性能特性进行分析，获得了储能电池单元内部的气流组织特性及电池表面的温度分布。在此基础上，研究了导流板的尺寸和布置角度对气体流动和传热特性的影响。研究结果表明：随着导流板宽度的增加，电池散热面的最高温度和平均温度都呈现下降的趋势；随着导流板布置角度的增加，电池散热面的最高温度和平均温度也呈现下降的趋势。通过导流板的合理布置可以使得电池散热面的温度降低到60 ℃以下，符合一般电池的合理工作环境。该研究结果对集装箱储能系统的广泛应用提供了技术参考。

Abstract:

The container energy storage system is an effective means of solving the energy waste problem caused by the mismatch between the generation and consumption peaks. The development of the container energy storage system is limited by the reason that the life of the lithium battery (hereinafter referred to as the battery) is affected by the batch battery consistency and the heating characteristics. The thermal performance of the battery module of a container energy storage system is analyzed based on the computational fluid dynamics simulation technology. The air distribution characteristics and the temperature distribution of the battery surface are then obtained. Moreover, the influence of the size and the arrangement angle of the guide plate on the gas flow and heat transfer characteristics is studied. The results show that the maximum and average temperatures of the cooling surface of the battery have a downward trend with the increases of the guide plate width and layout angle of the guide plate. The reasonable arrangement of the guide plate can reduce the temperature of the cooling surface of the battery to below 60 ℃, which is in line with the reasonable working environment of the general battery. The research results provide a technical reference for the wide application of the container energy storage system.

Key words: flow guide plate, angle arrangement, Fluent, air cooling, lithium-ion batteries, single factor analysis
