The invention provides an electric vehicle charging control method comprising the following steps: when a charging gun of the charging facility inserts into a charging port of to-be charged electric vehicle, a vehicle intelligent charging communication terminal arranged on the to-be charged electric vehicle can determine whether the to-be charged electric vehicle and the charging facility have set up physical connection or not; if yes, the vehicle intelligent charging communication terminal controls square wave signals on a charging cable; a charging facility intelligent charging communication terminal arranged on the charging facility collects the square wave signals on the charging cable, and determines whether the to-be charged electric vehicle and the charging facility have set up physical connection or not according to the square wave signal on the charging cable; if yes, the charging facility charges the to-be charged electric vehicle. The method can improve safety in the charging process; in addition, the invention also provides an electric vehicle intelligent charging system and the communication terminal.
