Comparison of heat transfer characteristics between air-cooled and liquid-cooled energy storage battery modules
摘要
Abstract
[Objective]During the operation of lithium-ion energy storage batteries,a large amount of heat is generated,and high temperatures can lead to thermal runaway,affecting battery safety.The thermal management system is a key factor affecting the stability and efficiency of lithium-ion energy storage batteries.[Methods]Using numerical simulation methods,the heat transfer characteristics of parallel air-cooled and liquid-cooled battery modules are quantitatively compared and discussed,including heat transfer performance,flow resistance performance,overall flow heat transfer performance,and the influence of ambient temperature.[Results]The results show that when considering the maximum temperature and maximum temperature difference of the battery module,there is a threshold for the temperature difference between the inlet and outlet of the cooling medium in the selection between air-cooled and liquid-cooled methods.The overall temperature uniformity of the liquid-cooled method is better than that of air-cooled,with a temperature difference of only 0.5℃between each cell,while air-cooled shows 6.1℃.The heat transfer performance of the liquid-cooled method is better than that of air-cooled,while the flow resistance performance of the liquid-cooled method is inferior to that of air-cooled.However,overall,the comprehensive flow heat transfer performance of the liquid-cooled method is better than that of air-cooled,and the performance advantage gradually increases with the increase in cooling medium flow rate.In the environment temperature range of 0℃to 30℃,the liquid-cooled method has a stronger ability to adapt to environmental temperature changes than air-cooled,with its heat transfer performance beingless affected by environmental temperature,resulting in a maximum temperature increase of only 1.1℃.[Conclusion]The research methods and results described in this paper can provide references for related research,which is conducive to the further optimization of energy storage cooling methods.关键词
