摘要：

随着工商业储能电池能量密度的持续提升、多场景应用范围的不断拓展，加之高温高湿工况对电池热管理提出的严苛要求，系统热失控风险隐患更加凸显。然而，在高温高湿环境下，液冷系统的性能缺乏实验研究。本工作基于高温/高湿环境和电池连续充放电情形，测试分析了冷源侧设备运行和能耗特性、输配系统的供回液温度、末端侧冷板表面以及电池温度。实验结果表明：对比30 ℃、RH=30%工况，高温40 ℃、RH=30%工况下压缩机、风机的启停频率降低了52%，冷却系统总能耗增加了39%，电池的纵向平均温差从2.82 ℃升高到3.14 ℃；在高湿环境(30 ℃、RH=70%)下，供液温度由20~25 ℃提高至24~28 ℃后，系统能耗降低了22%，电芯最大温度为40 ℃，相较之前提高了3 ℃，平均极差降低了22.56%，电池纵向平均温差从2.89 ℃降低到2.80 ℃。环境温度、湿度，以及供液温度对电池包内电池侧各界面的纵向温差无明显影响。

Abstract:

With the continuous improvement in the energy density of commercial and industrial energy storage systems and the expanding range of applications, coupled with stringent thermal management requirements under high-temperature and high-humidity conditions, the potential risk of thermal runaway has become increasingly significant. However, experimental research on liquid cooling system performance in such thermo-humidity environments remains limited. This study investigates the operational characteristics and energy consumption of cooling source equipment, supply-return liquid temperatures in distribution systems, as well as cold plate surface and battery temperatures under continuous charge-discharge conditions in high-temperature/high-humidity environments (40 ℃/30% RH, 30 ℃/30% RH, and 30 ℃/70% RH). Results demonstrate that, compared with 40 ℃/30% RH and 30 ℃/30% RH conditions, the start-stop frequency of compressors and fans decreased by 52%, total cooling system energy consumption increased by 28%, and the longitudinal weighted average battery temperature difference was reduced from 3.14 ℃ to 2.82 ℃. Under high-humidity conditions (30 ℃/70% RH), when the supply liquid temperature was increased from 20—25 ℃ to 24—28 ℃, system energy consumption decreased by 22%, with the maximum battery cell temperature rising by 3 ℃. The average maximum temperature difference decreased by 22.56%, and the longitudinal average temperature difference was reduced from 2.89 ℃ to 2.80 ℃. Ambient temperature, humidity, and supply liquid temperature showed no significant impact on the longitudinal temperature difference across battery cells within the pack.
