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.
