Research on discharge performance and capacity changes of lithium-ion batteries in wind farm energy storage systems
摘要
Abstract
This paper studies the discharge performance and capacity changes of lithium-ion batteries in wind farm energy storage systems.Through a well-designed experimental scheme and advanced testing technology,the performance and capacity and temperature changes of lithium-ion batteries at different discharge rates are systematically discussed.In the state of natural heat dissipation,the maximum temperature of the battery center is 69.87℃.After adding liquid cooling heat dissipation method,the maximum temperature of the battery center is 63.25℃,the temperature drops by 9.475%,the required heat dissipation time is reduced from 45 min to 25 min,and correspondingly,the temperature is reduced from 48.87℃to 35.00℃.Compared with natural heat dissipation,liquid cooling heat dissipation has a significant effect in the process of high-rate discharge,which not only reduces the temperature rise but also shortens the time required to reduce the temperature.The research results show that lithium-ion batteries exhibit good discharge performance in wind farm energy storage system applications under high discharge rate,but the discharge capacity will decrease to a certain extent as the rate increases.The research results of this paper not only provide theoretical support for the application of lithium-ion batteries in wind farm energy storage systems,but also provide practical guidance for optimizing their use and heat dissipation technology.关键词
