摘要
锂离子动力电池液冷热管理系统中,间接液基体系具有更广泛的应用,而其保证温度控制的关键部件是冷却板。本文所设计的铜管/铝板复合液冷板,研究了LiFePO_(4)锂离子动力电池模组液冷热管理系统的冷却效果。电池分别在3 C、4 C倍率下充放电;选取水作为冷却流体,冷却流体的进出口模式分别为二进二出、四进四出、六进六出模式;冷却流体入口流量分别为2 mL/s、4 mL/s、6 mL/s、8 mL/s、10 mL/s。实验结果表明,四进四出模式下、冷却流体流量为6 mL/s时,该液冷系统实现了在上述不同参数组合下的最优性能。该结果为进一步提高电池热管理系统的性能提供了重要的参考价值。
In the thermal management system of lithium-ion power battery,the indirect liquid-based system has a wider application.The major component in this system to ensure that temperature is controlled is the cooling plate.In this paper,the cooling effect of LiFePO_(4) lithium-ion liquid battery thermal management system using copper tube/aluminum plate composite liquid cooling plate is explored.The LiFePO_(4) lithium-ion battery module is at 3 C and 4 C charged-discharged rate,water is selected as coolant,and the import and export mode of coolant are two in/two out,four in/four out,six in/six out mode respectively.The inlet flow rate of the cooling water are 2 mL/s,4 mL/s,6 mL/s,8 mL/s and 10 mL/s,respectively.As shown in the experimental results,in four in/four out mode,when the flow rate of the cooling liquid is 6 mL/s,an optimum effect can be achieved under the above different parameter combinations,which provides an important reference for battery thermal management to further improving the working performance.
