  • Patent number: 10005371
    Abstract: System and methods for electric vehicle charging are described. A preferred charging rate associated with an electric vehicle is determined. The preferred charging rate is compared with a first charging rate associated with a utility service current source and a second charging rate associated with an electrical energy storage device. The utility service current source supports the first charging rate and the electrical energy storage device supports the second charging rate, where the second charging rate is greater than the first charging rate. A transfer switch is instructed to select one of the utility service current source and the electrical energy storage device based on the comparison. The transfer switch is coupled to an electric vehicle charger and supplies current to the electric vehicle charger via the selected current source. The electric vehicle is charged at the preferred charging rate using at least the selected current source.

  • Patent number: 9912160
    Abstract: Power control circuitry, power systems, and related methods are disclosed. A power system includes power control circuitry including a first power switch configured to couple a supplemental grid-synchronized power generator to a main grid power source, and a second power switch configured to couple the supplemental grid-synchronized power generator to a distribution unit configured to distribute electrical power to loads. The power control circuitry also includes time delay circuitry configured to control the first power switch and the second power switch. A method includes maintaining a supplemental grid-synchronized power generator coupled to a main grid power source while main electrical power is provided thereby, and decoupling the supplemental grid-synchronized power generator therefrom responsive to a cease in the main electrical power.

  • Patent number: 9333871
    Abstract: Systems, methods, and devices for refueling a vehicle are discussed herein. A vehicle charging station includes a power distribution interface, a receiver component, and an authorization component. The power distribution interface is configured to provide electrical power to a power receiving interface of a vehicle. The receiver component determines identification information that uniquely identifies the vehicle. The receiver component is positioned to determine the identification information corresponding to the vehicle when the power receiving interface is in electrical communication with the power distribution interface. The authorization component is configured to allow flow of electrical power to the vehicle in response to authorization based on the received identification information.

  • Publication number: 20160012657
    Abstract: Systems, methods, and devices for authorizing a vehicle for refueling are discussed herein. A method for authorizing a vehicle includes maintaining a list of preauthorized vehicles. The list of preauthorized vehicles includes entries uniquely corresponding to specific preauthorized vehicles. The list is maintained at a geographical charging site remote from one or more geographical charging locations. The method also includes transmitting to the geographical charging sites an update to the list of preauthorized vehicles. Each geographical charging site may include one or more charging stations. The method further includes receiving usage updates for the one or more geographical charging sites.

  • Patent number: 4107675
    Abstract: A transponder-responder system is provided which comprises a home station and at least one remote station. A transmitter at the home station periodically generates interrogation pulses by means of a directional sweep antenna across a search area. Each remote station includes a receiver and transmitter. Upon receipt of an interrogation pulse by the remote station receiver and while enabled, the remote station transmitter transmits a digitally encoded response signal which is received by a receiver at the home station. Upon receipt of the response signal by the home station receiver, timing circuitry at the home station determines the distance between the home and remote station by measuring the elapsed time between the transmission of the last interrogation pulse and the receipt of the response signal. Additionally, the home station includes circuitry which determines the rotational position of the sweep antenna and circuitry which decodes the response signal.
