Decision Study on Blockchain-Based Closed-Loop Supply Chain for New Energy Vehicle Power Batteries

Abstract: In the closed-loop supply chain management of power batteries for new energy vehicles, there are problems such as insufficient data transparency and traceability, inconsistent data, data tampering or leakage, difficulty in recycling and reusing power batteries, and low efficiency in supply chain management. The purpose of this article is to study how to optimize the management of the closed-loop supply chain of new energy vehicle power batteries based on blockchain technology. The specific goals include improving data transparency and traceability, solving the problem of information silos, enhancing data security, optimizing recycling and reuse mechanisms, and improving management efficiency. It proposed a solution based on blockchain technology, which improved the deficiencies in existing supply chain management through distributed ledgers and smart contracts. After the experiment, it was found that the blockchain-based solution achieved a data consistency of up to 98%, while the processing time also decreased. The research results indicate that blockchain-based supply chain management solutions significantly improve management efficiency and data security, promoting the efficient, secure, and sustainable development of the supply chain.
