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

A plurality of charging equipment share a current capacity. A message is received that indicates a request for allocation of electric current through a first charging equipment of the plurality of charging equipment. Responsive to determining that granting the request would exceed the current capacity, the electric current is dynamically allocated among the plurality of charging equipment such that the first charging equipment is allocated electric current without exceeding the current capacity shared by the plurality of charging equipment.

Managing electric current allocation between charging equipment for charging electric vehicles

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 system and method for managing a plurality of electric vehicles with a fleet management portal is described herein. In one embodiment, a machine implemented method for managing one or more fleets of electric vehicles includes monitoring one or more fleets of electric vehicles using a fleet management portal associated with a server. Next, the method includes monitoring a plurality of charge transfer devices using the fleet management portal. Next, the method includes receiving charging information from the charge transfer devices. Next, the method includes determining a charging status for each electric vehicle based on the charging information. Next, the method includes generating one or more reports having the charging status for each electric vehicle.

System and method for managing electric vehicles

An electric vehicle charging station network includes multiple electric vehicle charging stations belonging to multiple charging station hosts. Each host controls one or more charging stations. A charging station network server provides an interface that allows each of the hosts to define one or more pricing specifications for charging electric vehicles on one or more of their electric vehicle charging stations belonging to that host. The pricing specifications are applied to the charging stations such that a cost of charging electric vehicles using those charging stations is calculated according to the pricing specifications.

Electric vehicle charging station host definable pricing

A plurality of charging equipment for charging electric vehicles share a current capacity. A first charging equipment of the plurality dynamically allocates electric current among the plurality of charging equipment such that the maximum amount of electric current capacity is prevented from being exceeded while permitting each of the plurality of charging equipment to charge an electric vehicle.

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

Electric vehicle charging station

A first and second charging equipment for charging electric vehicles share a current capacity. A controller coupled with the first and second charging equipment limits a total amount of current drawn through the first charging equipment and the second charging equipment to not exceed the current capacity. A first and second current limit is communicated to a first and second electric vehicle respectively to limit the current draw of first and second electric vehicle to the first and second current limit respectively. A sum of the current drawn at the first and second current limit does not exceed the current capacity.
