Abstract

The invention discloses a communication method and system for orderly charging scheduling of an electric vehicle cluster in a residential area. Comprising the following steps: S1, integrating electric vehicle charging resources in a residential area, and constructing a multi-stage charging communication system; s2, a cluster communication terminal in each residential area cluster distributes and issues a charging command with a timestamp, and whether time delay exists or not is judged according to the timestamp fed back by the charging pile; if the time delay exists, a charging command is transmitted through the adjacent charging pile; and S3, the trunking communication terminal in each residential area cluster polls upwards at a fixed frequency, and if the polling feedback time exceeds the set polling feedback threshold time, the trunking communication terminal requests the cloud server to receive a charging command in the next polling period. And for different links with delay, different data interaction modes are switched, so that the method is more targeted, and timely and accurate communication is guaranteed.

本发明公开了一种居住区电动汽车集群有序充电调度的通信方法及系统。包括：S1：整合居住区电动汽车充电资源，构建多级充电通信系统；S2：每个居住区集群中的集群通信终端分配下发带时间戳的充电命令，根据充电桩反馈的时间戳判断是否存在延时；若存在延时，则通过相邻充电桩传递充电命令；S3：每个居住区集群中的集群通信终端以固定频率向上轮询，若轮询反馈时间超过设定的轮询反馈阈值时间，则该集群通信终端在下一轮询周期内向云端服务器请求接收充电命令。对于存在延时的不同环节，切换不同的数据交互方式，更具有针对性，保障通信的及时准确。
