Patent application number | Description | Published |
20100207588 | Detecting and Responding to Unexpected Electric Vehicle Charging Disconnections - An electrical vehicle charging station establishes a charging session with an electric vehicle which includes energizing a power receptacle in the charging station and receiving a charging cord at the power receptacle. While the charging session is established and responsive to detecting that a charging connection between the electric vehicle and the electric vehicle charging station has been unexpectedly disconnected, the power receptacle is de-energized to prevent electricity from flowing through the charging cord. | 08-19-2010 |
20100211340 | SYSTEM AND METHOD FOR MANAGING ELECTRIC VEHICLES - 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. | 08-19-2010 |
20100211643 | Transmitting Notification Messages for an Electric Vehicle Charging Network - 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. | 08-19-2010 |
20100301809 | OVERCURRENT AND GROUND FAULT PROTECTION IN A NETWORKED CHARGING STATION FOR ELECTRIC VEHICLES - A networked charging station for electric vehicles protects against overcurrent and ground fault conditions. Upon detecting an overcurrent condition or a ground fault condition, the networked charging station for electric vehicles de-energizes a charging point connection to prevent electric current from flowing between an electric vehicle and the networked charging station and suspends the charging session. The networked charging station clears the overcurrent condition or the ground fault condition upon receipt of an authorized request which is transmitted remotely. The authorized request can be received from the vehicle operator that is associated with the charging session or from an administrator of the charging station through a radio-frequency identifier (RFID) tag enabled device or through a text message or an email message. The networked charging station clears the overcurrent condition or the ground fault condition without a manual reset of a circuit breaker or a GFCI device respectively. | 12-02-2010 |
20100315197 | AUTHORIZATION IN A NETWORKED ELECTRIC VEHICLE CHARGING SYSTEM - 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. | 12-16-2010 |
20110095723 | OVERCURRENT AND GROUND FAULT PROTECTION IN A NETWORKED CHARGING STATION FOR ELECTRIC VEHICLES - A networked charging station for electric vehicles protects against overcurrent and ground fault conditions. Upon detecting an overcurrent condition or a ground fault condition, the networked charging station for electric vehicles de-energizes a charging point connection to prevent electric current from flowing between an electric vehicle and the networked charging station and suspends the charging session. The networked charging station clears the overcurrent condition or the ground fault condition upon receipt of an authorized request which is transmitted remotely. The authorized request can be received from the vehicle operator that is associated with the charging session or from an administrator of the charging station through a radio-frequency identifier (RFID) tag enabled device or through a text message or an email message.

20110191265 | ELECTRIC VEHICLE CHARGING STATION HOST DEFINABLE PRICING - 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. | 08-04-2011 |
20130090936 | Configurable Visibility of Electric Vehicle Charging Stations - In one embodiment, an electric vehicle charging network server provides an interface for electric vehicle charging station owners to selectively configure whether their electric vehicle charging station(s) are displayable on a charging station locator application to a specific set of one or more electric vehicle operators. For example, the interface may allow an electric vehicle charging station owner to specify that one or more of its charging stations are capable of being displayed on a charging station locator application to only a group of one or more electric vehicle operators (those charging station(s) will not be displayed on a charging station locator application used by other electric vehicle operators). | 04-11-2013 |
