摘要
电动汽车动力电池的退役潮来临,大量退役动力电池的处理成为当前的一大难题,将其规模化应用于储能系统是解决该问题的有效途径,研究梯次储能的经济性对促进规模化应用具有重大现实意义。首先分析了梯次储能系统的成本构成,并采用平准化成本模型分析了梯次储能的成本参数敏感性。其次,分析了退役电池梯次利用现状,探讨了梯次利用关键技术发展趋势;最后分析了梯次储能规模化应用时在实现盈利和优于新电池情况下的边界值,为梯次利用提供参考。
The tide of electric vehicle power battery decommissioning is approaching, and the disposal of numerous retired power batteries has currently become a major problem. An effective way to solve this problem is by applying them to energy storage systems on a large scale.Research on the economics of cascaded energy storage will promote scale. The application has significant practical importance. First, the cost types of the cascade energy storage system are analyzed, and its cost sensitivity parameters are analyzed using the levelized cost model. Second, it analyzes the current state of echelon usage of decommissioned batteries and discusses the development trend of key echelon usage technologies. Finally, it analyzes the boundary values of profitability and superiority over new batteries in the large-scale application of echelon energy storage to guide echelon usage.
