The method of an electric vehicle network, device and system

The present invention discloses a method of an electric vehicle network, devices and systems. The method comprising: receiving a network access request Network Control Center transmitted; forwards the network access request to the user terminal; electric vehicles receiving information sent by the UE for the network access request generated feedback information and the car terminal, wherein the feedback information comprises: agrees network, not agrees network; based on feedback information, information of the electric vehicle, the charge and discharge the collected information generating device discharge strategy; policy charging and discharging control center is fed back to the grid. The invention solves the existing network technologies lack of interaction of electric vehicle users and the center of the grid, resulting in electric vehicle users not flexible implementation problems electric car network.
