摘要

电池组热管理系统是保障高功率锂离子电池安全稳定运行的核心关键技术，其中基于相变材料（PCM）的相变-对流耦合热管理系统是目前重点研发方向之一。建立了锂离子电池组PCM-空气和PCM-水耦合冷却系统的仿真模型，并对比了这些热管理系统与传统空气和水冷却系统的性能差异。模拟结果显示，相较于传统空气冷却系统，PCM-空气耦合冷却系统的平均温度和最高温度在4 C高放电倍率下，分别降低40.8 ℃和49.7 ℃；对比传统水冷系统，PCM-水耦合冷却系统在4 C下，也能使电池平均温度与最高温度降低11.9 ℃和24.0 ℃。针对PCM-空气和PCM-水耦合冷却系统，进一步研究了流体流速、放电倍率等操作条件，以及PCM厚度、形状、流道设计等结构参数对冷却性能的影响，获得了较优的操作条件和结构参数。这些研究结果可为锂离子电池组热管理系统的设计开发提供强大的模型工具和实用的理论基础。

Abstract

Battery thermal management systems represent core technologies for ensuring the safe and stable operation of high-power lithium-ion batteries. Among these

phase change-convection coupled thermal management systems utilizing phase change materials (PCM) are currently a key research focus. This paper establishes simulation models for PCM-air and PCM-water coupled cooling systems in lithium-ion battery packs

comparing their performance against conventional air and water cooling systems. Simulation results indicate that compared to conventional air cooling systems

the PCM-air coupled cooling system reduces average and peak temperatures by 40.8 ℃ and 49.7 ℃

respectively

at a 4 C high discharge rate. When compared to traditional water cooling systems

the PCM-water coupled cooling system also lowers battery average and peak temperatures by 11.9 ℃ and 24.0 ℃ at 4 C. For both PCM-air and PCM-water coupled cooling systems

further investigations examine the influence of operational conditions—such as fluid flow rate and discharge rate—along with structural parameters including PCM thickness

shape

and flow channel design on cooling performance. Optimal operational conditions and structural parameters are identified. These findings provide robust modeling tools and practical theoretical foundations for the design and development of thermal management systems for lithium-ion battery packs.
