Embodiment Construction

[0044] figure 1 It is a flow chart of Embodiment 1 of the power monitoring method of the charging station of the present invention. The power monitoring method of this embodiment is used to monitor the power of multiple charging terminals on the low-voltage side of the transformer, and the following steps are performed in each monitoring cycle:

[0045] S101. Obtain the current total charging power of multiple charging terminals in the current monitoring period.

[0046] In this step, the total charging power of multiple charging terminals subordinate to the low-voltage side of the transformer can be collected through the electric energy meter.

[0047] S102. Obtain the maximum available power of multiple charging terminals in the current monitoring period.

[0048] S103. Determine whether the current total charging power is greater than the maximum available power, if yes, execute step S104; if not, execute step S106.

[0049] S104. Set the monitoring cycle to a first prese...

Abstract

The present invention relates to a power monitoring method, device and system for a charging station. In each monitoring period, the power monitoring method includes the following steps that: the current charging total power of a plurality of charging terminals in a current monitoring period is acquired; the maximum available power of the plurality of charging terminals in the current monitoring period is acquired; whether the current total charging power is greater than the maximum available power is judged; if the current total charging power is greater than the maximum available power, the monitoring period is set to be a first preset value according to a preset high-level monitoring policy; and a first power control parameter is calculated according to the current charging total power and the maximum available power, and sends the first power control parameter to the plurality of charging terminals. With the power monitoring method, device and system for the charging station of the invention adopted, the power utilization of the charging station can be maximized under the premise of the normal power usage of users of residential communities is ensured or the charging station does not operate in an overloaded manner.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a power monitoring method, device and system for a charging station. Background technique [0002] In recent years, the electric vehicle industry has developed rapidly and has been widely used in the field of public transportation. With the gradual maturity of technology and market, it is gradually being promoted and applied in the fields of logistics and private cars, and its popularity is getting higher and higher. The number of charging facilities is one of the key factors for the widespread development and promotion of electric vehicles. At present, charging facilities include independent charging stations and charging stations set up in residential areas. [0003] For an independent charging station, it is connected to a dedicated power distribution system. During the peak period of use, the charging module of the charging station is fully loaded and the amount of us...
