基于区块链技术的充电桩运维系统研究

面对电动汽车大规模推广应用对充电桩高效运维管理的需求，首先在介绍区块链技术基本原理的基础上，分析了充电桩运维系统的高分布性、多主体性和高可信性特征，归纳了区块链技术在充电桩运维系统上的应用价值，然后构建了基于联盟链式结构、采用PBFT共识机制、包含完全和不完全两类节点的区块链充电桩运维系统。最后，结合具体应用场景给出了系统在服务层、管理层和数据结构层各个层面的详细功能。为充电桩、配电站、运维机构、检定机构和监管部门等多边利益主体构思了一种基于区块链的端到端透明化、高可信性的去中心化管理模式，为区块链技术在充电桩运维系统的落地实施提供了参考。

Research on a blockchain-based charging pile maintenance system

Given the demands of high efficiency maintenance of charging piles in large-scale electric vehicle application, this paper, based on the basic principle of the blockchain, analyses the high distributive, multi-agent, and highly reliable features of the charging piles maintenance system first. Then it continues with the application value of a blockchain in a charging piles maintenance system. Thirdly, a blockchain-based charging piles maintenance system is proposed by using alliance chain style, adopting a PBFT consensus mechanism, and including complete & incomplete nodes. Finally, according to specific application scenarios, the functions of the proposed blockchain-based charging piles maintenance system are analyzed from the aspects of service, management and data structure levels. The proposed blockchain-based charging piles maintenance system is able to provide an end-to-end transparent and high reliability management mode for multi-agents including the charging pile, power distribution station, maintenance, calibration and supervision institutions. This provides an example of the implementation of blockchain technology in a charging pile maintenance system.
