摘要

相变材料（PCM）在电力存储和电力管理应用中具有吸引力。在本文中，PCM用于电池组的热管理。使用熔融温度为58°C的石蜡、熔融温度为35°C的OM35、两种PCM（石蜡和OM35）作为两种不同比例（50:50和60:40）的混合物进行研究。计算和实验用于估计锂离子电池模块中使用的PCM的传热、固化和熔融特性。由于PCM具有低导热性，因此研究了通过将铜板插入PCM混合物中来提高导热性的热改进技术。与PCM组合60:40相比，PCM组合50:50能够保持电池运行温度。PCM组合50:50证明是理想的，并将电池组的工作温度降低到47°C。

Experimental study of lithium-ion battery cooling using mixture of phase change materials

Phase change materials (PCM) are of attractive interest in electricity storage and power management applications. In this paper, PCMs are used for thermal management of an electric battery pack. Paraffin with a melting temperature of 58°C, OM35 with melting temperature of 35°C, two PCMs (paraffin and OM 35) were used for the study, as mixtures at two different ratios (50 : 50 and 60 : 40). Computations and experiments were allotted to estimate the heat transfer, solidifying and melting characteristics of the PCM utilised in the Li-ion cell battery module. Since PCM has low thermal conduction, thermal improvement techniques were investigated by inserting the copper plate into the PCM mixtures to boost the thermal conduction. PCM combination 50 : 50 is capable of holding battery running temperature compared to PCM combination 60 : 40. PCM combination 50 : 50 evidences to be ideal and lowered the operating temperature of the battery pack to 47°C.
