Numerical Investigation of Parallel Airflow-Cooled Lithium-Ion Battery Pack

  • 摘要: 合理有效的电池组热管理系统是提高电动汽车安全性能与工作寿命的关键。本文采用计算流体动力学(CFD)方法研究了锂离子电池组并行风冷热管理系统的冷却效果。考察了来流空气速度、温度对电池组最高温度(Tmax)和最大温差(ΔT)的影响,并从速度场结果解释了温度场的分布。在对原始模型温度场分析的基础上,本文对该模型进一步进行了几何优化,以提高电池组的空间利用率。结果显示:随着单体间距(S)的增大,Tmax及ΔT均逐渐增大;改变偏移角θ,电池组Tmax出现显著降低,且增大楔形风道角度(ω),ΔT不断减小。优化后的模型经证明温度场分布更加合理。
