摘要:

针对电动汽车充电困难与私有充电桩闲置率高的问题,以区域内的电动汽车和私有充电桩为研究对象,设计了基于区块链的私有充电桩共享机制。对电动汽车的出行路线、充电时刻及用户心理进行建模,计算电动汽车对充电桩的综合评价指标,以真实反映电动汽车对充电桩的偏好程度;建立了共享平台的充电交易机制,以求取计及区域内充电压力的动态电价。通过区块链技术和代理权益证明共识机制,保障交易的安全性。仿真结果表明:所提策略能为电动汽车用户提供额外的充电选择,缓解充电压力,同时可为私有充电桩所有者带来一定收益;所设计共识机制能对虚假信息进行有效防范。

Abstract:

Aiming at the charging difficulty of electric vehicles and the high idle rate of private charging piles, this paper took electric vehicles and private charging piles as the research objects, and designed the sharing strategy mechanism of private charging piles based on blockchain. To truly reflect the preference degree of electric vehicles to charging piles, the travel route, charging time and user psychology of electric vehicles were modeled, and the comprehensive evaluation index of electric vehicles to charging piles was calculated. The charging trading mechanism of the sharing platform was established to obtain the dynamic electricity price that takes into account the charging pressure in the region. The blockchain and delegated proof of stake consensus mechanisms were used to ensure the security of transactions. The simulation results show that the proposed strategy can provide additional charging options for electric vehicle users to relieve charging pressure and bring certain benefits to the owners of private charging piles. The designed consensus mechanism can effectively prevent false information.

Key words: blockchain, electric vehicle, charging pile, sharing mechanism
