Distributed type alternating-current charging system

Abstract

The invention discloses a distributed type alternating-current charging system. The system comprises a centralized controller used for acquiring charging information and payment information, a power distribution cabinet, charging piles and a cloud platform, wherein the charging information at least comprises user identity information, selected charging pile codes, the charging power and charging time; the charging information and the payment information are sent to the cloud platform; after a charging permission instruction sent by the cloud platform is acquired, a control instruction is sentto metering and billing modules in the power distribution cabinet according to the charging information; the power distribution cabinet comprises the metering and billing modules corresponding to thecharging piles one to one; the metering and billing modules are connected between an external power supply and the charging piles, the metering and billing modules receive control instructions sent bythe centralized controller and control the on-off state between the corresponding charging piles and the external power supply; the charging piles are used for charging when the external power supplyis connected; the cloud platform is used for sending the charging permission instruction after confirming the charging information and the payment information. The system is used for solving the problems of centralized configuration and centralized management.

Description

technical field [0001] The invention relates to the technical field of AC charging, in particular to a distributed AC charging system. Background technique [0002] With the popularization of electric equipment, especially electric vehicles, AC charging systems suitable for charging electric equipment have been widely used accordingly. [0003] At present, the AC charging system mostly adopts an independent structure, such as figure 1 As shown, one set of charging system corresponds to one vehicle charging interface. [0004] see figure 1 , the existing charging system appears in the form of charging piles, each charging pile is an independent charging system, including vehicle interaction module, metering and billing module, human-computer interaction module, background communication module and other parts, each charging pile Both are independently connected to the cloud platform. [0005] Since the current AC charging system uses such as figure 1 The structure shown i...

AI Technical Summary

Problems solved by technology

[0006] 1. A single charging pile adopts an independent configuration, and the hardware cost is too high;

[0007] 2. A single charging pile is directly connected to the cloud platform, and the wiring in the station is complicated;

[0008] 3. A single charging pile is connected to the Internet independently, and each charging pile needs to be equipped with a 4G / WIFI module, and the communication cost is relatively high;

[0009] The above disadvantages lead to high initial investment and construction costs of AC charging stations. As the simplest charging method, it is not suitable for mass promotion
