摘　　要：为实现混合式电池热管理系统质量最小化,并满足电池散热性能要求,建立由电池生热模型和相变材料传热模型组成的电池系统仿真模型,利用中心复合有界设计法建立试验设计表,使用响应曲面法和Screening优化算法得到电池系统最优设计,并考察复合相变材料厚度和组成对系统性能的影响。结果表明:最优方案与原方案相比,可使系统质量减少62.7%,体积减少33.3%,最高温度降低10.8%,最大温差低于5℃。In order to make minimize the mass of a designed hybrid battery thermal management system(BTMS),and meet the requirements of battery heat dissipation performance,a coupled numerical simulation model for BTMS was established,which consists of a single cell heat production model and a composite phase change material(CPCM)heat transfer model.Secondly,the table of DOE was established using center composite inscribed design,and then the optimal design was obtained by response surface method and screening optimization algorithm.In the meantime,the effects of the thickness and composition of the expanded graphite/paraffin on the system performance were investigated.The results indicate that compared with the original design,the optimized design can reduce the system mass by 62.7%,the volume by 33.3%,the maximum temperature by 10.8%,and the maximum temperature difference is less than 5℃.
