New energy vehicle charging port cover control method and device

The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle charging port cover control method and device. After the charging gun is pulled out, through radio frequency communication between the charging gun and a vehicle, a gun pulling signal of the charging gun is transmitted, the radio frequency communication module transmits the gun pulling signal to the vehicle body controller, the vehicle body controller drives the electric charging port cover to be opened and sends the state of the charging port cover to the vehicle machine system, and the vehicle machine system displays the state through an instrument large screen.
