Systems and methods for charging management of charging devices

A charging management method executed by a computer device for controlling a charging schedule of an electric vehicle charging device, wherein the power consumption for the electric vehicle charging device and the power consumption for a facility are cumulatively added to a same power meter for calculating utility bill during a billing period, the method comprising:

• monitoring the power consumption for the facility to obtain facility power consumption data;
• and
• obtaining the facility power consumption data and time-variant electricity pricing data applied to the power meter and controlling the charging schedule of at least one electric vehicle by the electric vehicle charging device based on the facility power consumption data and the time-variant electricity pricing data,
• wherein the facility power consumption data includes present power consumption for the facility and a historical power consumption record for the facility, and the method further comprises determining whether the present power consumption of the facility is higher than a first predetermined value, and when the present power consumption of the facility is higher than the first predetermined value, controlling the electric vehicle charging device to start the charging procedure in the time period during which the facility power consumption in the historical power consumption record is lower than a second predetermined value according to the historical power consumption record.
