百兆瓦（MW）级大规模储能电站日益增多，对储能大容量化技术的需求更加迫切。电网对大容量储能系统的并网友好性有更高要求。就储能系统而言，电池簇精细化管理的内部需求凸显，同时储能集成系统成本压力增加，也需要整体管控。从仿真角度分析发现，储能Pack的液冷板存在降本空间，故本文采用尺寸优化的方法，以液冷板质量最小为优化目标，截面厚度尺寸为设计变量，Pack静强度为约束条件，使液冷板的整体质量下降25.2%。根据减重优化后的尺寸结果构建新的储能Pack模型，发现减重后的液冷板可使Pack内的电芯温度更加均一，静强度均小于材料的屈服强度，道路运输分析的最大置信应力均小于材料屈服强度，满足设计强度要求。

The number of large-scale energy storage stations with a capacity of over 100 MW is increasing, leading to a more urgent need for large-capacity energy storage technology. The power grid has higher requirements for the grid-connection friendliness of large-capacity energy storage systems. In terms of energy storage systems themselves, the internal demand for refined management of battery clusters has become prominent. At the same time, the cost pressure on energy storage integrated systems necessitates overall control. Through simulation analysis, the author found potential cost reduction in the liquid-cooled plate of the energy storage Pack. Therefore, this paper adopts a size optimization method, aiming to minimize the mass of the liquid-cooled plate, with the cross-sectional thickness as the design variable and the static strength of the Pack as the constraint condition, achieving an overall 25.2% reduction in the weight of the liquid-cooled plate. Based on the optimized size results, a new energy storage Pack model was constructed. It was found that the liquidcooled plate with optimized size made the cell temperatures within the Pack more uniform, with static strengths all below the yield strength of the material. Road transport analysis showed that the maximum confidence stress was also below the material's yield strength.
