摘　　要：锂离子电池在工作过程中会放出大量的热,长时间工作会导致电池长期处于高温环境中,对电池的性能和寿命造成严重影响。文章设计了一种基于液冷板和相变材料结合的动力锂电池散热系统,对比分析了不同的介质、不同的初始温度、不同的水流速对电池散热的影响。结果表明,在初始温度为25℃,水的流速为0.2m/s时,采用水+相变材料的方式对电池进行散热效果最佳。Lithium-ion batteries will release a lot of heat during the working process,and long-term work will cause the battery to be in a high temperature environment for a long time,which will seriously affect the performance and life of the battery.In this paper,a battery thermal management system based on liquid and phase change material cooled is designed.The infl uence of different media,different initial temperature and different water fl ow rate on the heat dissipation of battery is compared and analyzed.The results show that when the initial temperature is 25℃and the fl ow rate of water is 0.2m/s,the method of water+phase change material is the best for heat dissipation of the battery.
