  • Patent number: 8278875
    Abstract: A safety supervisory module (SSM) of an electric vehicle charging station that controls flow of current from the electric vehicle charging station to an electric vehicle. The SSM includes a set of two or more processors to control operation of a contactor control circuitry of the SSM to open and close a set of contacts of a set of power supply lines to control flow of current from the charging station to an electric vehicle. Each processor independently determines whether an unsafe condition exists and asserts a relay enable signal to the contactor control circuitry only when an unsafe condition does not exist.

  • Publication number: 20120135626
    Abstract: A self powered electric vehicle charging connector locking system for locking and unlocking a charging connector of an electric vehicle charging cord includes an electric vehicle charging station and an electric vehicle charging connector locking holster. The charging station includes an electricity control device to energize and de-energize the charging cord to control a supply of electricity available to flow through the charging cord. Current does not flow through the charging cord when it is de-energized and some amount of current is capable of flowing through the charging cord when it is energized. The locking holster includes a charging connector locking holster inlet to receive the charging connector of the charging cord and a locking unit to lock the charging connector in the locking holster when it is inserted into the locking holster inlet and unlock the charging connector from the locking holster responsive to the charging cord becoming energized.

  • Patent number: 8129425
    Abstract: The present invention makes available methods and reagents for modulating proliferation or differentiation in a cell or tissue comprising contacting the cell with a hedgehog agonist, such as the compounds depicted in FIGS. 32 and 33. In certain embodiments, the methods and reagents may be employed to correct or inhibit an aberrant or unwanted growth state, e.g., by antagonizing a normal ptc pathway or agonizing smoothened or hedgehog activity.

  • Publication number: 20110316482
    Abstract: Electric vehicle charging stations are coupled with a circuit sharing controller. Multiple electric vehicle charging stations are wired on the same electrical circuit. The circuit sharing controller implements a circuit sharing process that dynamically allocates electric current to charging stations on the same electrical circuit such that the capacity of the electrical circuit is not exceeded while permitting each of those charging stations to draw electric current through that electrical circuit for at least some amount of time.

  • Publication number: 20110316478
    Abstract: 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.

  • Publication number: 20110316479
    Abstract: A vehicle charging station that includes a power receptacle compartment that includes a power receptacle to receive an electrical plug. The vehicle charging station also includes a door that is hingedly coupled with the power receptacle compartment to cover the power receptacle when the door is closed. The vehicle charging station includes a first locking means for locking and unlocking the door from a closed position without consuming power to control access to the power receptacle compartment such that the door remains locked in the closed position if the vehicle charging station loses power. The vehicle charging station also includes a second locking means for locking and unlocking the door from a charging position to control access to the electrical plug. The second locking means allows the door to be unlocked from the charging position if the vehicle charging station loses power.

  • Patent number: 8072184
    Abstract: 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.

  • Publication number: 20110133693
    Abstract: 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.
