  • Patent number: 9201408
    Abstract: A total amount of current drawn through a first charging equipment and a second charging equipment that wired on a same electrical circuit is limited to not exceed a maximum amount of electric current supported by the electrical circuit to prevent the electrical circuit from being overloaded, where limiting includes communicating a first current limit to a first electric vehicle connected to the first charging equipment to cause the first electric vehicle to limit its current draw to not exceed the first current limit, and communicating a second current limit to a second electric vehicle connected to the second charging equipment to cause the second electric vehicle to limit its current draw to not exceed the second current limit, where a sum of current being drawn at the first current limit and the second current limit does not exceed the maximum amount of electric current supported by the electrical circuit.

  • Patent number: 9201407
    Abstract: A message is received that indicates a request for an allocation of electric current at a first electric vehicle charging station that is connected to a same main electrical circuit breaker as a second electric vehicle charging station that is presently allocated electric current. Responsive to determining that granting the request would exceed a maximum amount of electric current supported by the main electrical circuit breaker, the electric current allocation of at least the second electric vehicle charging station is adjusted such that the request for allocation can be granted and the request is granted and electric current is allocated to the first electric vehicle charging station.

  • Patent number: 8852937
    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: 20140210412
    Abstract: 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.

  • Publication number: 20130310999
    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.

  • Patent number: 8460028
    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.
