摘　　要：建立了锂离子电池的热特性模型,将电池内部复杂的层状结构当作一种均质的各向异性材料,求得电池的平均热特性参数.利用ANSYS ICE-PAK计算流体动力学软件对强迫风冷电池箱内的流场和温度场进行了仿真分析,并且对通风冷却方案进行了优化.同时研究了放电倍率、风扇风量和风道尺寸等因素对电池箱温度场的影响.A lithium-ion battery thermal model was established.The complicated layered structure within the battery was considered as a homogeneous and anisotropic material,and the average thermal characteristics were calculated.The fluid field and temperature field in the battery chassis cooled by forced air were simulated numerically by using the CFD software ANSYS ICEPAK,and then the ventilation cooling system was optimized.The paper also demostrated the effect of battery discharge rate,fan flow rate and duck dimension on the temperature distribution in the chassis.
