[Objective]To trace an electric vehicle battery effectively,a battery tracing system for electric vehicles based on the alliance chain is built.[Methods]This paper analyzes the strength and weakness of the existing domestic electric vehicle battery tracing scheme and proposes an electric car battery tracing system with privacy protection,which deploys alliance chain nodes on all traceable links where terminals are presented by radio frequency tags.[Results]Specifically,this paper gives the design of the system including the overall architecture,core node functionality,system cooperative traceability process and data process.[Limitations]The cost of data storage is relatively high and further optimization is needed to improve system efficiency.[Conclusions]The electric car battery tracing system realizes comprehensive supervision and traceability for six links in battery production,assembly,sales,maintenance,scrapping and logistics.
