集装箱式储能电站两相冷板液冷系统的温控效果研究
Study on the temperature control effect of a two-phase cold plate liquid cooling system in a container energy storage power station
摘要
Abstract
Long-term high temperatures and temperature differences can damage battery performance and lifespan.Therefore,a novel two-phase cold plate liquid cooling system has been developed for large-scale energy storage,and its temperature control effect has been measured at an energy storage power station in Xiangtan City,Hunan Province.First,the control effect of the two-phase cold plate on battery temperature variation and temperature consistency across the entire cabin and each box during the entire charging and discharging process is examined.Subsequently,the temperature variation in the battery after charging and discharging is analyzed.The results indicate that two-phase cold plate cooling can effectively mitigate temperature increases and improve the temperature consistency of the battery,reducing the maximum temperature difference from the traditional liquid cooling system range of 4.17℃to within 3℃during charging and discharging.Under identical conditions,the heat dissipation of the battery during charging exceeds that during discharging.If the cooling system is not turned on during the static phase,the phenomenon of elevated battery temperatures inside the power station will persist for 80 minutes or longer.关键词
