随着插电式混合动力汽车的发展，大多数插电式混合动力汽车都配备了双向充电器。然而，在能量交易过程中，集中式方案暴露出许多缺陷，如能量传输损耗高，不能抵抗单点故障。因此，采用分散的方式来保证AHEV之间的安全能量交易就显得尤为重要。在本文中，我们提出了一个分散的能源交易架构中，AHEV可以广播他们的要求，邻居和其他AHEV的传输参数没有交易服务器进行协商。智能合约（SC）部署在RSU之间，可以在协商过程后自动执行。为了促进AHEV在道路上的诚实行为，我们将AHEV的信任值与充电价格相关联。我们使用概念验证，从理论上证明了发展的SC和安全性能的建议计划的可行性。仿真结果表明，所提出的协商方案在效率方面优于非协商方案。
With the development of the autonomous hybrid plug-in electric vehicles (AHEVs), majority of AHEVs are equipped with bidirectional chargers. However, during the energy trading process, the centralized schemes are exposed to many flaws like the high energy transmission loss and cannot resist the single-point failure. Therefore, it is more important to use the decentralized manner to keep the safety energy trading between AHEVs. In this paper, we propose a decentralized energy trading architecture in which AHEVs can broadcast their requirements to neighbors and negotiate with other AHEVs on the transmission parameters without a transaction server. The smart contract (SC) is deployed among RSUs which can be automatically executed after the negotiation process. To promote AHEVs to behave honestly on the road, we associate the trust value of AHEVs with the charging price. We use proof-of-concept to theoretically demonstrate the feasibility of the development of the SC and the security properties of the proposed scheme. The simulation results demonstrate the proposed negotiation scheme outperforms the non-negotiation scheme in the aspect of efficiency.
