摘　　要：随着电动汽车保有量的不断增加,充电桩的集群控制面临着挑战,而充电桩集群控制在一定程度上取决于充电桩的通信组网性能。为满足充电桩集群控制的需求,解决零散充电桩通信组网困难的问题,提出一种基于信道预测技术的充电桩自适应通信组网方法。利用基于改进回声状态网络的信道技术预测充电桩间的信道状态信息,评估充电桩间的通信环境,选择最优的充电桩通信主节点构建充电桩通信组网。仿真结果表明,所提出的信道预测技术可以准确地预测充电桩间的信道状态信息,具有良好的单步预测和多步预测性能,可以实现充电桩的有效通信组网。With the increasing numbers of electric vehicles,the cluster control of charging piles,which depends on the communication network performance of charging piles to a certain extent,is facing challenges.To meet the demand of charging pile cluster control,especially to solve the problem of scattered charging pile communication networking,this paper proposes a charging pile adaptive communication networking method based on channel prediction technology.It uses the channel technology based on improved echo state network to predict the channel state information between charging piles,further evaluate the communication environment,and construct the charging pile communication network by selecting the optimal charging pile communication master node.The simulation results show that the channel prediction technology proposed in this paper can accurately predict the channel state information between charging piles,has good performance of single step prediction and multi-step prediction,and can realize effective communication networking of charging piles.
