ABSTRACT:
A system for network-controlled charging of electric vehicles comprises charge transfer devices networked as follows: charge transfer devices and electric vehicle operators communicate via wireless communication links; charge transfer devices are connected by a local area network to a data control unit, which is connected to a server via a wide area network. The server stores consumer profiles and utility company power grid load data. A charge transfer devices comprises: an electrical receptacle for receiving an electrical connector for recharging an electric vehicle; an electric power line connecting the receptacle to a local power grid; a control device on the electric power line, for switching the receptacle on and off; a current measuring device on the electric power line, for measuring current flowing through the receptacle; a controller for operating the control device and monitoring the output from the current measuring device; a local area network transceiver connected to the controller, for connecting the controller to the data control unit; and a communication device connected to the controller, for wireless communication between the operator of the electric vehicle and the controller.
