基于联盟区块链的新能源企业智能电动汽车充电系统

Intelligent Electric Vehicle Charging System for New Energy Enterprises Based on Alliance Block Chain

新能源电动车需求的日益扩增进一步提升了电动车充电的需求,然而各运营公司之间的间隙导致充电桩信息无法全面并切实地面向需求大众。针对上述问题,介绍了一种基于联盟区块链的新型智能电动汽车充电系统。首先,通过联盟区块链使得系统具备防篡改、多中心化等特点;之后,提出了生物目标混合整数规划模型(BOMILP)来平衡企业和电动汽车用户之间的利益,并在此基础上,引入一种支持智能合约实现的有限领域记忆搜索算法(LNSM),以进一步提升智能合约运行速度及性能;最后,以天津地区的电动车充电数据为例,验证了所提出系统的有效性和可行性。

The growing demand for new energy electric vehicles(EVs)has further boosted the demand for electric car charging.However,the gap between operating companies results in that the information of charging piles cannot be fully and effectively presented to the demanding public.Aiming at the above problems,a new intelligent EV charging system based on alliance block chain was introduced.Firstly,the system was tamper-proof and multicentralized through the alliance block chain.Then,a bio-objective mixed-integer programming model(BOMILP)was proposed to balance the interests between enterprises and electric vehicle users.A limited neighborhood search method with memory(LNSM)algorithm supporting the implementation of smart contract was introduced to further improve the speed and performance of smart contract.Finally,the charging data of electric vehicles in Tianjin area was taken as an example to verify the proposed system,the results show that the method is feasible.
