摘　　要： 充电桩共享是解决充电难的创新服务模式。分析了中心化共享平台在信用体系、信息安全、收益分配以及数据共享等方面的弊端,指出具有分布式点对点、去中心化、共识信任机制和信息不可篡改等特点的区块链技术是实现共享系统的理想选择。由于单项技术难以满足复杂应用系统的多样化需求,所以需要多项技术相互作用,互为补充。提出基于区块链、闪电网络和智能合约技术,形成区块链生态系统,构建安全、高效和自动化的共享平台。结合电动汽车充电场景,说明基于闪电网络的支付网络的建立和基于哈希密钥逐级验证的智能合约的实现过程。最后,展望了该方案在售电管理、需求响应管理及新能源消纳等方面构建能源区块链的应用可能性。 Charge pile sharing is an innovative service mode to solve charging problems. This paper analyzes the drawbacks of the centralized sharing platform in credit system, information security, revenue distribution and data sharing, and points out that the block chain technology, which has the characteristics of distributed point-to-point, de-centralization, consensus trust mechanism and information immutability, is the ideal choice for implementing sharing system. Since individual technology is difficult to meet the diverse needs of complex application systems, a number of technical interactions need to be used to complement each other. Based on block chain, lightning network and smart contract technology, this paper proposes a block chain ecosystem to build a secure, efficient and automated sharing platform. Combining electric vehicle charging scenarios, this paper presents the establishment of the payment network based on the lightning network and the realization of the smart contract based on the hash key verification. Finally, the application possibility of energy block chain in the aspects of electricity sales management, demand response management and new energy accommodation is discussed.
