在电池单体间及电池与电池仓体间填充泡沫铝,建立电动汽车锂离子电池模块散热的多孔介质三维模型,并对其温度场和多孔介质处的速度场分别进行了仿真,在此基础上提出了锂离子电池模块的结构优化方案,优化后锂离子电池模块的最高温度下降4.4℃、温差下降3.2℃的同时,电池模块的体积减小了12.95%。
Foam aluminum is filled between the battery cells and between the battery and the battery compartment to establish a three-dimensional porous media model for the cooling of the lithium-ion battery module of the electric vehicle. The temperature field and the velocity field at the porous media are respectively simulated. Based on this, Proposed lithium-ion battery module structure optimization program, optimized lithium-ion battery module maximum temperature dropped 4.4 ℃, the temperature drop of 3.2 ℃ at the same time, the battery module size decreased by 12.95%.
