Research progress in liquid cooling and heat dissipation technologies for electrochemical energy storage systems
摘要
Abstract
With advancements in lithium-ion battery technology and decreasing costs,large-scale lithium-ion battery energy storage systems are transitioning from demonstration phases to commercial applications.Optimizing the design of battery thermal management systems is crucial for enhancing the overall performance of energy storage systems.Effective temperature control not only extends the lifespan and discharge capacity of energy storage batteries but also plays a vital role in ensuring the safe operation of power plants.As large-scale electrochemical energy storage power stations increasingly rely on lithium-ion batteries,addressing thermal safety concerns has become urgent.The study compares four cooling technologies—air cooling,liquid cooling,phase change material cooling,and heat pipe cooling—assessing their effectiveness in terms of temperature reduction,temperature uniformity,system structure,and technology maturity.The findings indicate that liquid cooling systems offer significant advantages for large-capacity lithium-ion battery energy storage systems.Key design considerations for liquid cooling heat dissipation systems include parameters such as coolant channels,cold plate shapes,and types of coolant used.Furthermore,the liquid cooling system can be optimized in conjunction with other cooling methods to enhance the thermal performance of the system.By refining control targets and algorithms,intelligent and precise management of battery module temperature can be achieved,thereby improving the overall efficiency of the thermal management system.Liquid cooling technology requires ongoing optimization in several areas,including key system parameter design,control strategy development,and application requirements,to achieve effective temperature control and meet economic and efficiency goals.关键词
