主 题:Lithium ion battery thermal management system air-cooling temperature rise
摘 要:The heat generation model and three-dimensional computational fluid dynamics model for lithium ion cells were established with boundary conditions *** order to provide a better insight about the behaviors of high-power lithium ion cells under realistic discharge conditions,the temperature difference of the cells and an active thermal management system with a pure air-cooling mode were analyzed and predicted with the factors affecting the unevenness of temperature field *** results show a significant effect of the cooling flow rate on the temperature rise of the cells for all discharge *** surface temperatures are relatively uniform at lower discharge rate that makes it easier to control the temperature of the *** temperatures are expected to rise significantly toward the end of discharge and they show non-uniformity at higher discharge *** air flow rate of active cooling is required at high discharge rate and high ambient temperature for practical pack thermal management system.
