The invention discloses a power management method for multiple charging devices, the charging devices and a charging station, and belongs to the technical field of charging. A plurality of charging devices are in communication connection to form a local area network, one charging device in the local area network is a host, the other charging devices are slaves, and the method comprises the steps that the host obtains power information of the slaves and power information of the host, and power information of the plurality of charging devices is obtained; the host acquires power information of charging stations where the plurality of charging devices are located; and the host performs power adjustment on the plurality of charging devices based on the power information of the plurality of charging devices and the power information of the charging station. According to the method, one charging device in the station is used as a host to carry out power adjustment on all charging devices in the station, an extra energy management and control terminal does not need to be arranged, overload of a transformer can be effectively prevented, the station building cost cannot be increased, meanwhile, all charging devices in the station can achieve the power management function, and the operation stability of the charging station is guaranteed.
本申请公开了一种多个充电设备的功率管理方法、充电设备及充电站,属于充电技术领域。多个充电设备通信连接组成局域网,局域网中一个充电设备为主机,其余的充电设备为从机,该方法包括:主机获取从机的功率信息以及主机自身的功率信息,得到多个充电设备的功率信息;主机获取多个充电设备所在的充电站的功率信息;主机基于多个充电设备的功率信息和充电站的功率信息,对多个充电设备进行功率调节。该方法通过将站内一个充电设备作为主机对站内所有充电设备进行功率调节,无需设置额外的能量管控终端,可以有效防止变压器过载,不会增加建站成本,同时站内所有充电设备都可实现功率管理功能,保证充电站运行的稳定性。
