Embodiment 1

[0026] Such as figure 1 As shown, in Embodiment 1, the charging pile based on the electric vehicle charging cluster specifically includes several charging subsystems and several communication modules, and the charging subsystem realizes two-way communication with the server through the communication module. The communication module realizes two-way data communication, and then confirms the main charging subsystem and the secondary charging subsystem.

[0027] Further, several charging subsystems are connected to the same distribution transformer, and the charging subsystem includes a main charging subsystem and a slave charging subsystem that adjust the output power according to the rated power of different electric vehicles, and the main charging subsystem receives each charging subsystem. The power consumption information of the middle charging gun and the real-time electric load information of the charging pile area sent by the server, and then control the start-stop workin...

Embodiment 2

[0033] This embodiment has the same inventive concept as Embodiment 1. On the basis of Embodiment 1, a charging pile server based on an electric vehicle charging cluster is provided. The server includes a first information sending unit, a second information sending unit, and a second information sending unit. An information receiving unit, a second information receiving unit, a judging unit and a data storage unit. Specifically, the first information sending unit is used to send the real-time electric load information of the area where the charging pile belongs to the main charging subsystem; the second information sending unit is used to send status confirmation information, main charging subsystem confirmation information and slave charging subsystem Confirm the information. Among them, the status confirmation information is used to confirm whether each charging subsystem is online, so as to confirm whether the charging subsystem is faulty, and to repair it in time by techni...

Embodiment 3

[0036] This embodiment has the same inventive concept as Embodiment 1 and Embodiment 2, and on the basis of Embodiment 1, a method for controlling a charging pile based on an electric vehicle charging cluster is provided. Such as figure 2 As shown, the methods specifically include:

[0037] S01: Regularly update the rated power data information corresponding to different brands and models of electric vehicles in each charging subsystem; specifically, the charging subsystem regularly receives data update packets sent from the server to update the data stored in the database unit The car's power rating information. As a preference, the server sends a data update packet to the charging subsystem during idle hours, so as to avoid affecting the communication between the server and the charging subsystem, and between the charging subsystem and the charging subsystem during peak periods of network usage.

[0038] S02: Confirm the main charging subsystem and the secondary charging ...

Abstract

The invention discloses a charging pile based on an electric vehicle charging cluster and a server, and belongs to the technical field of charging pile control, the charging pile comprises a pluralityof charging subsystems and a communication module, the plurality of charging subsystems are connected to the same distribution transformer, and the charging subsystems realize bidirectional communication with the server through the communication module, wherein the charging subsystem comprises a main charging subsystem and a slave charging subsystem which are used for adjusting output power according to rated power of different electric vehicles; and the main charging subsystem receives the charging information of a charging gun in each charging subsystem and the real-time electrical load information of an area to which the charging pile belongs sent by the server, and controls the start-stop working state and the output power of each charging gun. According to the invention, the load ofthe power grid in the peak period of power utilization can be reduced, the rated powers of different electric vehicles can be adjusted to adjust the output power of the charging guns, the charging efficiency is high, the unified allocation of the charging guns under the same distribution transformer is realized, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of charging pile control, in particular to a charging pile and a server based on an electric vehicle charging cluster. Background technique [0002] Low-carbon travel is a highly recommended travel mode at present. Electric vehicles are favored by more and more people because of their high efficiency and low pollution. With the popularization of electric vehicles, various charging piles are gradually put into use, and a large number of charging piles are installed, which requires corresponding power distribution capacity for support. At present, each charging pile cannot adjust the output power according to the rated power information of different electric vehicles, and cannot charge electric vehicles efficiently and quickly; secondly, there is no information interaction between charging piles, and it is impossible to obtain all charging piles in a certain distribution transformer area The real-time output ...
