摘要
从三维非稳态导热微分方程出发,利用无量纲分析法推导了锂离子电池内部温度场相似所应满足的相似准则,并确定了实物对象与模拟对象之间的温度场相似关系。利用ANASYS软件进行了单层结构和多层结构锂离子电池温度场的有限元建模与计算,验证了所建立相似准则和相似关系的正确性。
From the three dimensional transient temperature differential equation,the dimen- sional analysis method is used to derive similarity criterions and the similarity coefficients of battery in- terior temperature fields. To validate the similarity criterions and the similarity coefficients,three di- mensional finite element models of battery temperature field are established,on the assumption that the battery has single-layer structure and multi-layers structure. The simulation results show that the simi- larity criterions and the similarity coefficients are certified correct.
