Thermal management of large‐scale Li‐ion battery packs is of great significance to their safety and life cycle, which would impact their applicability in electric vehicles. Of the many strategies developed for this purpose, indirect liquid cooling has already demonstrated quite high potentials in thermal regulation of such battery systems. In this study, a compact lightweight serpentine wavy channel configuration was chosen to construct an indirect liquid cooling system for a battery module of cylindrical Li‐ion cells. The serpentine channel has a number of six internal minichannels. Experimental test data were used to conduct a comprehensive thermal analysis to examine the highest temperature, the maximum temperature difference, and the heat accumulation percentages, and so forth within the battery pack. Results have revealed the ability of the cooling system to maintain the module temperature within appropriate working conditions for electric vehicle applications for most cycling tests including two driving cycles. Furthermore, the analysis insights raised by this study could be useful in understanding the cooling performance of the liquid‐based thermal management systems for electric vehicles.

基于蛇形通道的锂离子电池热管理系统的性能:实验研究
大型锂离子电池组的热管理对其安全性和生命周期至关重要,这将影响其在电动汽车中的适用性。在为此目的开发的许多策略中,间接液体冷却已经显示出在这种电池系统的热调节中的相当高的潜力。在这项研究中,选择了紧凑的轻型蛇形波浪通道配置,以构造用于圆柱形锂离子电池的电池模块的间接液体冷却系统。蛇形通道具有六个内部微型通道。实验测试数据用于进行全面的热分析,以检查电池组中的最高温度,最大温差和热量累积百分比等。结果表明,对于包括两个行驶循环在内的大多数循环测试,冷却系统都能将模块温度保持在电动汽车应用的适当工作条件内。此外,本研究提出的分析见解可能有助于理解电动汽车基于液体的热管理系统的冷却性能。
