为了降低锂离子电池的最高温度和最大温差，本文以方形磷酸铁锂电池为研究对象，采用相变微胶囊悬浮液浸没式冷却方式，对不同放电倍率下的电池的散热性能进行了研究。结果表明：对于单体电池在质量分数为12.5%、浸没量为0.6时，散热效果最佳。在此条件下，对电池组在环境温度为35℃、3 C放电倍率下进行实验，电池组的平均最高温度和最大温度不均匀性分别约为38℃、3℃，可以满足电池组正常工作温度要求。
Abstract：To reduce the maximum temperature and temperature difference of lithium-ion batteries, square lithium-iron phosphate batteries are focused on as the research subject in this paper. By using a phase change microcapsule suspension liquid immersion cooling method, the thermal management performance of batteries under different discharge rates is studied. The research indicates that the optimal cooling effect for individual cells is achieved at a mass fraction of 12.5% and an immersion ratio of 0.6. Under these conditions, experiments on battery packs at an ambient temperature of 35 °C and a discharge rate of 3 C show that the average maximum temperature of the pack is approximately 38 °C, with a maximum temperature non-uniformity of about 3 °C, which meets the normal operating temperature requirements of the battery pack.
