Evaluation and recovery of power batteries based on trusted blockchain traceability

Abstract In order to solve the new threats to human health and the earth environment brought by the large number of discarded power batteries in the future, we propose a method of power battery evaluation and recovery. We use trusted block chain technology to build a scientific, efficient and reliable power battery evaluation and recovery platform, through the power battery production, sales, use and recovery process, contact the manufacturers, dealers, users, charging stations, and other nodes. At the same time, through the battery built-in BMS system and wireless communication terminal, real-time access to the battery usage and performance parameters. When it is detected that the power battery meets the recycling standard, the battery can be transported to the waste battery treatment center through the logistics network established by the manufacturer. The treatment center uses alkaline precipitation and biocatalysis to centrally process the recycled materials and realize the recycling of the recycled materials. The method breaks down the technical barriers in the field of power battery evaluation and recovery, and provides scientific, efficient and advanced support for environmental protection.
