电池舱热管理方案的优化设计

Optimization Design of Thermal Management Scheme for Battery Container

针对目前大容量储能电池集装箱存在的电池工作温度高、电芯温度不均匀问题,从电池集装箱的结构设计、风道设计入手,利用有限元软件进行辅助分析,验证集装箱内各电池模组间温度分布的合理性。试验验证发现,经优化设计后的电池舱实现了舱内不同模组间温差小于8 K的设计目标,为功率型电池舱的大规模推广应用提供了良好的案例。

In order to solve the problems of high and uneven temperature of battery cell in large capacity energy storage battery container at present,starting with the structural design and air duct design of battery container,the finite element software is used for analysis to verify the rationality of temperature distribution between battery modules in the container.According to the experimental verification,the optimized battery compartment has achieved the design goal that the temperature difference between different modules is less than 8K.It provides a good case for the promotion and application of power battery compartment.
