摘要
由于锂离子动力电池对环境温度敏感,电池液体热管理技术对温度的控制效果良好,针对液体热管理技术在电池热管理中的应用及其效果进行综述。以液体冷却技术和液体加热技术为研究切入点,通过综述这两种技术在锂离子动力电池热管理中的应用现状,深入分析其对电池温度控制的效果。研究表明,液冷板式冷却效果好但系统复杂,未来需优化轻量化和安全性设计;液冷管道冷却轻量但应用受限,需进一步探索;浸没式液体冷却能显著降低电池温度并提升均匀性,但需解决密封及动态行驶中的散热问题;滴落式液体散热精度高、质量轻,是未来研究热点;液体加热可快速预热电池包,一体化设计可提升效率并降低成本。
Since lithium-ion power batteries are sensitive to environmental temperature,and the battery liquid thermal management technology has a good effect on temperature control,this paper aims to review the application of liquid thermal management technology in battery thermal management and its effect.Taking liquid cooling technology and liquid heating technology as the research starting point,by reviewing the current status of the application of these two technologies in the thermal management of lithium-ion power batteries,in-depth analysis of its effect on battery temperature control.The study shows that liquid cooling plate cooling is effective,but the system is complex,and needs to optimize the lightweight and safety design in the future;liquid cooling pipe cooling is lightweight,but the application is limited,and needs to be further explored;Submerged liquid cooling can significantly reduce the battery temperature and improve the uniformity,but it needs to solve the sealing and heat dissipation in dynamic driving;drop liquid cooling is highly accurate and lightweight,and is a hotspot of future research;liquid heating can quickly preheat the liquid heating can quickly warm up the battery pack,and the integrated design can improve the efficiency and reduce the cost.
