摘要
以某车用锂离子电池组为研究对象,主要研究了爬坡工况、90km/h匀速工况和NEDC三种工况下动力电池组的温升情况。利用STAR-CCM+和Amesim软件联合对液冷电池包进行热管理仿真,分析流场和温度场的分布情况,预测综合工况下电池包模组的最高温度和模组间温差分布,并通过热管理试验验证三种工况下试验结果与仿真结果是否吻合,以提高仿真精度。
A lithium-ion battery pack for a vehicle is taken as the research object,and the temperature rise of the power battery pack under three driving cycles(called climbing cycle,constant speed of 90 km/h cycle and NEDC cycle)is studied.By using STAR-CCM + and Amesim software co-simulation,thermal performance of liquid-cooled battery pack,the distribution of flow field and temperature field are evaluated,and the maximum temperature of the battery pack and the temperature difference between modules under comprehensive driving cycles are predicted.Furthermore, the actual performance results are obtained through thermal management test to improve the simulation accuracy.
