Abstract
The echelon use of power batteries is considered as an efficient recycling method which can effectively extend the service life of power batteries and reduce costs. The echelon use of power batteries is encouraged by national policies and widely concerned in the industry so it has quickly became a hot spot among the issue about industry development. This article compares and analyzes the battery standard requirements for power batteries and the intended application fields of echelon use and the economics of using lead-acid batteries and decommissioned power batteries in different application fields. This article initially draws the conclusions about the technical and economic feasibility of echelon use of power batteries.
Highlights
OverviewThe number of new energy vehicles (NEVs) promoted and used in China has risen rapidly, while some power batteries have begun to enter into a period of scrap
Many relevant entities in the upstream and downstream of the industrial chain, such as power battery manufacturers including CATL and Hefei Guoxuan, automobile manufacturers including SAIC, BAIC and BYD, third-party echelon use companies including ZTDL, GEM and Huayou, echelon use user companies including China Tower and State Grid, colleges and universities as well as scientific research institutions, have begun to carry out relevant research, construct demonstration projects and explore business models in the field of echelon use of power batteries
China's power battery echelon use applications have been concentrated in related fields, such as backup power supply used in communication base station, energy storage of power system and low-speed electric vehicles etc
Summary
The number of new energy vehicles (NEVs) promoted and used in China has risen rapidly, while some power batteries have begun to enter into a period of scrap. The subsequent recycling and utilization of power batteries has attracted great attention from the society and relevant government authorities, which have gradually begun to formulate and improve the policies and standards related to recycling of power batteries. Echelon use of power batteries is encouraged by national policies and widely concerned in the industry, so it has quickly became a hot spot among the issue about industry development. China's power battery echelon use applications have been concentrated in related fields, such as backup power supply used in communication base station, energy storage of power system and low-speed electric vehicles etc
