摘　　要：为改善光伏电站储能热效率,提高系统安全和稳定性,对电储能散热问题进行研究,设计了一套完善的热管理方案,并采用有限元分析软件对电池、电池簇及集装箱整体进行建模和热性能仿真评估。数据结果表明,采用四级管路结构设计和板换式水冷机组降温,可以有效降低集装箱内部电池间温差,保证电芯温差控制在5℃以内,集装箱内温控范围控制在15-35℃,延长整个系统的使用寿命以及运行的安全可靠。本文提高的光伏电站储能系统热管理方案,从电池包到电池簇,再到集装箱系统,每一个环节均安全可靠,性能表现良好。In order to improve the thermal efficiency of the photovoltaic power station energy storage system and enhance its safety and stability,this study investigates the heat dissipation issues of energy storage,designs a comprehensive thermal management scheme,and utilizes finite element analysis software to model and simulate the thermal performance of the batteries,battery clusters,and the entire container.The data results indicate that the use of a four-level pipeline structure design and plate heat exchanger-based water cooling system can effectively reduce the temperature difference between the batteries inside the container,ensuring that the temperature difference of the battery core is controlled within 5℃ and the temperature within the container is maintained within the range of 15 to 35℃.This approach extends the overall system's service life and ensures safe and reliable operation.The enhanced thermal management scheme for the photovoltaic power station energy storage system demonstrates excellent performance,with each component from the battery pack to the battery cluster and the container system being safe and reliable.
