动力电池梯次利用研究概况

Review on echelon utilization of power battery

随着电动汽车产业的快速发展,退役动力电池数量将越来越大。推动动力电池梯次利用,从经济、资源安全、节能环保等多个角度来看,都具有十分重要的现实意义。总结了近年来国内外建设的梯次利用电池储能示范电站,阐述了铅酸、锂电池等主要梯次电池储能系统的应用场景及安全性,对比分析了铅酸电池和磷酸铁锂电池梯次利用的经济性,对动力电池梯次利用的工程应用进行了探讨并提出建设性意见。

With the rapid development of the electric vehicle industry,the scale of decommissioning of power batteries will become larger and larger.Promoting the use of power battery ladders is of great practical significance from the perspectives of economy,resource security,energy conservation and environmental protection.This paper summarizes the use of battery energy storage demonstration power stations built in recent years at home and abroad,and expounds the application scenarios and safety of lead-acid battery storage systems such as lead-acid,lithium battery,and compares and analyzes the utilization of lead-acid and lithium elevators.Economics,and finally discussed the engineering application of power battery ladder utilization and put forward constructive opinions.
