基于280A·h方块电池组风冷热管理单元的仿真研究
Simulation of air-cooling thermal management unit based on 280A·h prismatic energy storage battery packs
摘要
Abstract
A novel air-cooling thermal management unit based on 280A·h high-capacity battery with micro-porous plate was developed and simulated by ANSYS Fluent.The"U"-type air duct was selected to investigate the temperature and velocity distributions of the battery packs with or without porous plate,and with different porous plate thicknesses,air velocities,ambient temperatures and discharge rates.The results showed that the addition of porous plate effectively improved the velocity distribution and enhanced the temperature uniformity of battery packs,and increasing the thickness significantly reduced the maximum temperature.Increasing air velocity could reduce the maximum temperature and balance the inside temperature difference of the battery packs.In addition,when the thickness was 6mm,the discharge rate was 1C,the air speed was 10m/s and the ambient temperature was 25℃,the maximum temperature was 36.51℃ and the maximum temperature difference was only 1.55℃.This novel micro-porous plate type air-cooled thermal management unit was able to quickly remove the heat generated in battery packs operated under high current,thus significantly improving the service life and the safety and reliability of the energy storage battery packs.关键词
