The invention discloses an electric automobile intelligent orderly charging system which is suitable for a community distribution transformer and comprises a data acquisition unit and a data server. The data acquisition unit is installed on a gateway of the community distribution transformer and used for acquiring voltage and current data of the community distribution transformer in real time andthen sending the voltage and current data to the data server; the data server is used for receiving the voltage and current data of the community distribution transformer in real time, obtaining the real-time load rate of the community distribution transformer, and cutting off a charging loop of a resident personal charging pile in real time when the real-time load rate of the community distribution transformer is greater than a preset community distribution transformer load rate threshold value; and when the difference value is smaller than the threshold value, a charging loop of the residentpersonal charging pile is controlled and turned on in a preset valley period. According to the invention, the charging requirement of residents on electric vehicles can be safely and reliably met byutilizing the existing distribution transformer of the community without adding a transformer substation, and the economic operation efficiency of distribution transformers of a community is improved.
本发明公开了一种电动汽车智能有序充电系统,适用于小区配电变压器,包括数据采集单元和数据服务器,其中:数据采集单元,安装在小区配电变压器的关口上,用于实时采集小区配电变压器的电压和电流数据,然后发送给数据服务器;数据服务器,实时接收小区配电变压器的电压和电流数据,获得小区配电变压器的实时负载率,当小区配电变压器的实时负载率大于预设小区配电变压器负载率阈值时,实时切断居民个人充电桩的充电回路;而当小于该阈值时,在预设低谷时段内控制导通居民个人充电桩的充电回路。本发明无需增加变电站,利用小区现有的配电变压器,即可安全、可靠地满足居民对电动汽车的充电需求,提高小区的配电变压器的经济运行效率。
