Aiming at the problems such as lagging standards, easy data tampering, and difficulty in multi-party collaboration in the field of on-site inspection and testing of new energy charging facilities, combined with the pain points of low efficiency and easy tampering of electronic reports in the traditional inspection and testing mode, this paper proposes a detection and traceability system for new energy charging facilities based on the Hyperledger Fabric consortium chain. The system adopts a four-layer architecture of user layer, application layer, blockchain layer and data layer, integrates technologies such as smart contract and JSON Web Token (JWT) authentication, and realizes trusted evidence storage of detection data. Innovate the hierarchical storage strategy of "storing business data on the chain MySQL+storing file hashes on the chain" to break through the performance bottleneck of blockchain. Through modules such as user management, inspection application, and result on-chain, a collaborative network among the owner, inspection party, and regulatory party is constructed, compressing the traditional inspection process from several days to the hour level. This fills the application gap of blockchain in this field, provides technical support for the quality assurance of charging facilities, and has positive significance for promoting the implementation of the "dual carbon" strategy.
