A multi-charging-pile networking control system and method based on power coordination

Abstract

The invention discloses a multi-charging-pile networking control system and method based on power coordination. The system comprises a charging pile host, a plurality of charging pile slaves, a charging control device, a wireless communication device and a background server. The method comprises the steps that the charging pile host uploads load information to the background server, the backgroundserver calculates the load rate, and if the load rate exceeds the specified range, the charging pile host controls the charging pile slave to adjust the charging power; if the range does not exceed the specified range, whether a charging pile slave changes or not is judged, if yes, change information is uploaded to a charging pile host, and the charging pile host uploads load information in an area to a background server; if not, the charging pile host directly uploads load information in the area to a background server; And the background server sends heartbeat packets to the charging pile host regularly, and network disconnection networking is carried out again when a fault occurs. The networking method is simple and convenient, the data exchange efficiency is high, and power control over multiple charging piles in an area can be achieved.

Description

technical field [0001] The invention relates to the technical field of charging piles for electric vehicles, in particular to a control system and method for networking of multiple charging piles based on power coordination. Background technique [0002] Due to the increasing popularity of electric vehicles, more and more charging piles have been installed in residential areas, parking lots and other public places. However, most of the currently installed charging piles do not have networking functions. There is no information interaction between multiple charging piles in the area. Each pile is just an independent pile. If too many charging piles are connected to the grid, the capacity limit of the transformer may be exceeded, causing harm. [0003] Most of the existing charging pile power control only controls a single charging pile, and does not network charging load information for all charging piles in the area. There are some charging pile networking technologies that...

However, most of the currently installed charging piles do not have the function of networking. There is no information interaction between multiple charging piles in the area. Each pile is just an independent pile. Too many charging piles connected to the grid may exceed the transformer capacity limit, causing harm

[0003] Most of the existing charging pile power control only controls a single charging pile, and does not network charging load information for all charging piles in the area. There are some charging pile networking technologies that upload charging information to the server for background data storage. and monitoring, but the load information and control instructions are not effectively applied to the overall power control of charging piles
