摘要:

基于Ansys/Fluent有限元分析软件,对电网储能系统的磷酸铁锂储能电池进行建模,并对电池模块进行温度场和流场的仿真。仿真结果表明,电池机柜顶层与底层流体流量存在较大差异,导致不同电池模块层间温度分布不均匀,温差较大。对电池机柜前、后门进行改进,优化了前、后主风道,降低了电池机柜内的最高温度;在机柜门上增加导流板,改善了电池机柜内温度场和流场分布的均匀性,有效降低了不同电池模块间的温差。

关键词: 磷酸铁锂电池模块, 热仿真, 温度场, 流场, 挡风板

Abstract:

Based on the finite element analysis software of Ansys/Fluent,this paper built the model of lithium iron phosphate batteries and simulated the temperature field and flow field of the battery modules used in the power grid energy storage system.The simulation results show that there is a large difference in the fluid flow between the top layer and the bottom layer of the battery modules,leading a large uneven temperature difference between different layers of the battery module.By improving the front and rear doors of the battery cabinet,the front and rear main air passages were optimized to reduce the maximum temperature in the battery cabinet.Then,by adding deflector plates on the cabinet door,the uniformity of temperature field and flow field distribution in the battery cabinet was improved,and the temperature difference between different battery modules was effectively reduced.

Key words: lithium iron phosphate battery module, thermal simulation, temperature field, flow field, deflector plate
