Electric vehicle, charging device, charging system and method

Abstract

The invention discloses an electric vehicle, a charging device, a charging system and a method. An automatic identifying device of the electric vehicle comprises a RFID radio frequency identifying device for reading an electronic label on a charging gun, and a wireless transmission device for transmitting user identity information and electronic label information to an integrated controller of the charging device. After the integrated controller detects the connection between the electric vehicle and the charging gun and receives the user identity information and the electronic label information, the information is sent to a server for authentication; and after the server authentication is qualified, a charging instruction is given to the integrated controller, and the integrated controller is connected with a charging branch connected with the charging gun. Before the charging gun is connected with the electric vehicle, the charging gun is not electrified; after the charging gun is connected with the electric vehicle, the functions of identity identification and automatic charging can be performed; the charging process of the electric vehicle is largely simplified; and the charging method of the electric vehicle is safe, reliable and fast.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle, a charging device, a charging system and a charging method. Background technique [0002] With the increasing awareness of environmental protection and energy saving, electric vehicles are gradually favored because they are powered by on-board power supplies, which can solve the problems of fuel vehicle exhaust emissions polluting the environment and high energy consumption. And the charging problem of electric vehicle is the problem that people pay close attention to very much, and it is related to popularization and promotion of electric vehicle. [0003] The electric vehicle group charging device in the prior art includes a centralized controller, several charging branches and charging guns connected to the charging branches, wherein the charging gun is set on the parking space, and after the charging gun is connected to the electric vehi...

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 gun information to the server, and the server cannot send charging instructions. Electric cars can't be charged

2. Smart terminals such as mobile phones are fre...
