Identification device for electric automobile charging interfaces and charging device, system and method

Abstract

The invention discloses an identification device for electric automobile charging interfaces and charging device, system and method. The automatic identification device comprises a radio frequency identification device (RFID) and a wireless transmission device, wherein the RFID is used for reading electronic tags on the charging interfaces; the wireless transmission device is used for transmitting user identity information and electronic tag information to a centralized controller of the charging device; the centralized controller detects that an electric automobile is connected with the charging interfaces, receives the user identity information and the electronic tag information and then transmits the information to a server for identification; the server issues a charging instruction to the centralized controller after the identification is passed; and the centralized controller is communicated with charging branches which are connected with the charging interfaces. According to the identification device, the functions of not electrifying the charging interfaces before the charging interfaces are connected with the electric automobile, and carrying out identification and automatically beginning to charge after the charging interfaces are connected with the electric automobile are achieved; flow of beginning to charge the electric automobile is greatly simplified; and the method is a safe, reliable and rapid method for beginning to charge the electric automobile.

Description

AI Technical Summary

Problems solved by technology

This method generally uses smart terminals such as mobile phones to scan the QR code, and has the following disadvantages: 1. When the wireless signal is not good, smart terminals such as mobile phones cannot transmit user information and charging interface information to the server, and the server cannot send charging commands. Electric cars can't be charged

2. Smart terminals such as mobile phones are frequently used, consume a lot of power, and are prone to power outages. When the smart terminal is out of power, it is impossible to scan the QR code

3. When the external environment is relatively dark, the smart terminal cannot scan the QR code

4. The two-dimensional code is set on the charging interface by printing, which is easy to be defaced. After being defaced, the smart terminal cannot scan the two-dimensional code
