基于区块链技术的电动汽车充电链

Electric Vehicle Charging Chain Based on Blockchain Technology

近年来,为了降低对石油能源的消耗、对环境的污染,中国积极推动新能源汽车的发展,取得了很好的成效,电动汽车保有量连年激增。但是针对电动汽车的配套基础设施(充电桩)的发展却严重落后,电动汽车与充电桩的布局极不均衡,充电难已经逐渐成为制约电动汽车发展的主要因素。区块链技术具有去中心化、可追溯、不可篡改等技术优势,被广泛应用到金融、地产、医疗、物联网、教育等各个领域。针对电动汽车面临的“有车无桩,有桩无车”的现象,对电动汽车充电联盟链的可行性与创新性进行了深入的分析。系统阐述了区块链的技术背景,在此基础上提出了基于区块链技术的充电桩共享方案。详细阐述了充电桩共享系统的各个模块,包括底层区块链类型、区块链节点类型以及系统所采用的共识机制。最后提出系统实现的整个系统架构,系统动态模型。充电联盟链的建设,有利于消除电动汽车企业与充电桩运营商之间的信任壁垒,实现电动汽车车主与充电桩运营商之间的公平的价值转移,有效缓解现阶段电动汽车充电难的困境。

In recent years,in order to reduce the consumption of petroleum energy and pollution to the environment,China has actively promoted the development of new energy vehicles and achieved ideal results.The number of electric vehicles has increased dramatically year after year.However,the development of supporting infrastructure(charging piles)for electric vehicles is seriously backward.The layout of electric vehicles and charging piles is extremely uneven.The difficulty of charging has gradually become a major factor restricting the development of electric vehicles.Blockchain technology has the technical advantages of decentralization,traceability and non-tampering,which is widely used in various fields such as finance,real estate,medical care,Internet of Things and education.In view of the phenomenon of“no car,no pile,no car”,the electric vehicle has a deep analysis of the feasibility and innovation of the electric vehicle charging alliance chain.The technical background of blockchain is expounded systematically.Based on this,a charging pile sharing scheme based on blockchain technology is proposed.The modules of the charging pile sharing system are elaborated,including the underlying blockchain type,the blockchain node type and the consensus mechanism adopted by the system.Finally,the whole system architecture,system dynamic model realized by the system are proposed.The construction of the charging alliance chain is conducive to eliminating the trust barrier between the electric vehicle enterprise and the charging pile operator,realizing the fair value transfer between the electric vehicle owner and the charging pile operator,effectively alleviating the difficulty of charging the electric vehicle at this stage.
