基于动力电池热效应模型，通过Flotherm热仿真软件和SolidWorks结构建模软件，针对退役电池子模块、退役电池模组、退役电池储能系统(退役电池箱)，分析研究了影响退役电池箱散热性能的若干因素———电池单体摆放方式、电池间距、风道结构等。仿真结果表明，采用电池单体卧式摆放、电池间距6 mm的布局方式，且采用下部并行进风、上部并行出风风道结构的退役电池箱具有优异的散热性能，箱内各电池单体间隙最高工作温度小于45℃，温差小于5℃，符合工程化应用需求。

The effects of the laying styles of single cel s, spacing between cel s, air duct structure on the heat dissipation of retired battery box were investigated based on thermal model of battery by the Flotherm and SolidWorks software. The research subject includes sub-module of retired battery, module of retired battery and retired battery energy storage system (retired battery box). The simulation results show that the structure of retired battery box with horizontal arrangement of single cel s, 6 mm spacing between cel s, paral el route of air duct structure is the structure of more reasonable, which makes the maximum working temperature of the space between al single cel s in the retired battery box is less than 45 ℃, the temperature difference is less than 5 ℃, the requirements of practical engineering use is met.
