Networked electric vehicle charging stations for charging electric vehicles are coupled with an electric vehicle charging station network server that performs authorization for charging session requests while the communication connection between the charging stations and the server are operating correctly. When the communication connection is not operating correctly, the networked electric vehicle charging stations enter into a local authorization mode to perform a local authorization process for incoming charging session requests.

Authorization in a networked electric vehicle charging system

An electric vehicle charging station that is installed in a residence is coupled with a main circuit breaker in an electrical service panel. The charging station includes a charging point connection that couples an electric vehicle to a set of service drop power lines that provide electricity from a power grid to the residence; a current control device coupled to control the amount of electric current that can be drawn from the set of service drop power lines by an the electric vehicle through the charging point connection; a receiver to receive energy readings from one or more current monitors that indicate an amount of current is being drawn from the set of service drop power lines; and a set of control modules to cause the current control device to control the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings to avoid tripping the main circuit breaker.

Method and apparatus for management of current load to an electric vehicle charging station in a residence

An electric vehicle charging station network server that manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) that indicate one or more events of interest for which the subscriber wishes to receive notification messages. A set of one or more contact points associated with the subscriber is also received. The server receives data associated with the subscriber that indicates that a charging session at one of the charging stations has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

Transmitting notification messages for an electric vehicle charging network

A network-controlled charge transfer device for electric vehicles includes a control device to turn electric supply on and off to enable and disable charge transfer for electric vehicles, a transceiver to communicate requests for charge transfer with a remote server and receive communications from the remote server, and a controller, coupled with the control device and the transceiver, to cause the control device to turn the electric supply on based on communication from the remote server.

Network-controlled charging system for electric vehicles

A server of a network-controlled charging system for electric vehicles receives a request for charge transfer for an electric vehicle at a network-controlled charge transfer , determines whether to enable charge transfer, and responsive to determining to enable charge transfer, transmits a communication to the network-controlled charge transfer that indicates to the network-controlled charge transfer to enable charge transfer.

A charge transfer device for transferring charge between a local power grid and an electric vehicle is mounted to a street light. The charge transfer device includes a control device to control application of charge transfer between the local power grid and the electric vehicle. The charge transfer device is coupled to the local power grid through a wiring box that also couples the street light to the local power grid. The charge transfer device includes a current measuring device to measure an amount of current flowing for charge transfer. The charge transfer device includes a controller to cause the control device to control application of charge transfer and monitor output from the current measuring device.

Transferring charge between a local power grid and electric vehicles

An electric vehicle charging station network server which manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) which indicate one or more events of interest that the subscriber wishes to receive notification messages for. A set of one or more contact points associated with the subscriber is also received. The server authorizes the subscriber to use one of the plurality of charging stations. The server receives data associated with the subscriber from that one of the charging stations which indicates that a charging session has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

A network-controlled charge transfer device for transferring charge between a local power grid and an electric vehicle is mounted to a street light. The charge transfer device includes the following: an electrical receptacle to receive an electrical connector for connection to the electric vehicle; an electric power line that couples the power grid to the electrical receptacle through a wiring box; a control device to switch the receptacle on and off; a current measuring device to measure current flowing through the electric power line; and a controller to operate the control device and to monitor output from the current measuring device.
