Literature explores the reuse potential and cost analysis of retired electric vehicle batteries in green energy power systems, yet it lacks a long-term evaluation of the impact of performance degradation across different usage scenarios, potentially leading to an underestimation of the economic potential of the batteries.
The evaluation of retired batteries mainly focuses on the current state of the battery pack, which is used to decide whether the battery pack can be reused or further dismantled. The evaluation of the battery pack is divided into three parts: appearance inspection, electrical performance testing and final inspection.
In addition, retired batteries can not only be used to consume renewable energy, but also provide services such as frequency regulation for the grid to better utilize its performance. This paper analyzes the economics of retired batteries from EVs for use in PV-containing grids.
