Abstract：A thermal management system with dual air-liquid circulation was proposed based on the temperature homogeneitycontroland thedynamic temperature diferenceregulation toenhance the temperature uniformityin lithium-ion batterysystems for energy storage power stations.The systemutilizedair cooling under low-to-medium temperature conditions to combined air-liquid cooling in high-temperature environments. Simulationexperiments investigated 4controlparameters including theair volume，theair temperature，the coolant temperature，and thecoolant flowrate.The heat exchange structure wasoptimized through 1D-3D cosimulations toanalyzing the significanceof temperature riseand theuniformityof performance parameters. Theresults show that under twicethe rated high-power discharge，the proposed system reduces theend-ofdischarge temperature difference by 18% compared to the conventional bottom cold plate structures.A300 sairsupplycycleachievesa 31% reduction in the temperature difference （of 1.18∘C） versusa100scycle. Parametersensitivitydecreases in theorderas theair temperature，theairvolume，thecoolant temperature，and the coolant flowrate.Therefore，thedualair-liquid circulation designenhances dynamic temperature diference control with extending the service life of energy storage battery systems.
