Abstract

With the rapid development of China’s economy and the continuous rise in social electricity consumption, traditional distribution networks face the contradiction of peak-valley difference and the difficulties of dispatching management. Energy storage systems have become an important direction to solve this problem. This study systematically investigates liquid-cooled energy storage systems, demonstrating the feasibility of liquid cooling technology in large-capacity applications through theoretical modeling and thermal analysis. Using a 280Ah lithium iron phosphate battery assembled into a 1.066MWh liquid-cooled system, precise thermal modeling and optimized configuration enabled effective temperature control within the optimal range of 25℃±3℃ during 1C-rate discharge, with total heat generation of approximately 28kW. The research reveals that liquid-cooled systems exhibit significant advantages in heat dissipation efficiency, temperature control precision, and space utilization, providing reliable technical support for the safe and stable operation of large-capacity energy storage systems.
