摘要: 为了解决电动汽车用锂电池单元形状选择问题,通过依次分析锂电池单元性能评价指标、锂电池装配工艺评价指标和锂电池包性能评价指标等一系列影响因素;并以此为基础,应用层次分析法首先建立其评价模型,然后确定其主要的影响因素指标,最后以3种常用的不同形状的锂电池单元为例进行了说明。结果表明:相对于棱柱罐状锂电池单元和圆柱形锂电池单元而言,棱柱袋状锂电池单元具有更大的优势。Abstract: In order to address the shape choice of lithium battery cells for electric vehicle,according to analyzing orderly a series of evaluation index of the performance of lithium battery cell and lithium battery assembly process and lithium battery pack,and firstly AHP（analytic hierarchy process） algorithm is applied to establish the evaluation model,secondly the main factors were determined,finally three lithium battery with common and different shapes were used as an example,and the results show that comparing with prismatic tank-type cells and cylindrical type cells,the prismatic pouch-type cells have a greater advantage which provides a theoretical basis for the shape choice of electric vehicle with lithium battery cell.
