梯次利用电池在储能电站中应用的可行性分析

Application Feasibility Study of Cascade Utilization Battery in Energy Storage Power Station

通过对比分析梯次利用电池与新电池的全生命周期成本差异,建立了考虑电池寿命和运行特性的度电成本分析模型,用该模型分析了梯次利用电池与新电池以及铅炭电池的度电成本,探讨了梯次利用电池度电成本的影响因素,对退役电池梯次应用于储能电站的技术路线和应用方向给出了建议。

The differences between the whole life cycle cost of the cascade utilization battery and the new battery are compared and analyzed, and KWH cost analys model is established based on a consideration of the battery life and operating characteristics.Then the model is applied to case analyze the KWH cost among the cascade utilization batteries and new batteries and lead carbon batteries. The influencing factors on the KWH cost of cascade utilization batteries are discussed and some suggestions are put forward on the technical routes and application direction of the cascade utilization of returned batteries in energy storage power stations.
