Abstract

The popularity of electric vehicles depends on convenient and efficient charging services. At present, none of existing charging services allow users to reach charging stations at desirable time and charge immediately when they arrive without waiting. This paper proposes a charging reservation service approach based on the consortium blockchain and smart contract technology. Users can choose the charging station and charging time period with no charging congestion, which is based on the charging information recorded in the consortium blockchain composed of stations located in distributed regions in a city. To ensure a user arrives at the charging station on time and charge within due time as he/she has reserved, a personalized pricing scheme for reward and punishment by utilizing smart contract is proposed. We take the past charging behavior into consideration when deciding current charging price of each user, which can provide individualized prices for different users. This approach can not only greatly reduce the user’s waiting time, but also offer high cost-effective charging services for good behavior users. We carry out experimental verification under multiple sets of parameter settings, illustrate the variations in three aspects including user’s initial score, violation rate and intensity of reward and punishment, thus the feasibility of our approach is proved. Our work is a credible charging paradigm based on trust mechanism via blockchain, which has the potential to become an industry service standard for electric vehicle charging.
基于b区块链的电动汽车充电预约方法
电动汽车的普及有赖于便捷高效的充电服务。目前,现有的充电服务都不允许用户在理想的时间到达充电站,并在到达后立即充电,而无需等待。本文提出了一种基于联盟区块链和智能合约技术的收费预约服务方法。用户可以根据位于城市分布式区域的充电站组成的联盟区块链中记录的充电信息,选择不存在充电拥堵的充电站和充电时间段。为保证用户按时到达充电站并按预定时间充电,提出了一种基于智能合约的个性化奖罚定价方案。在确定每个用户当前的收费价格时,我们考虑了过去的收费行为,可以为不同的用户提供个性化的价格。这种方式不仅可以大大减少用户的等待时间,还可以为行为良好的用户提供高性价比的收费服务。我们在多组参数设置下进行了实验验证,说明了用户初始得分、违规率和奖惩力度三个方面的变化,从而证明了我们方法的可行性。我们的工作是通过区块链建立基于信任机制的可信充电范式,有可能成为电动汽车充电的行业服务标准。
