  • 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.

  • Patent number: 8967466
    Abstract: Systems, methods, and devices for refueling a vehicle are discussed herein. According to one embodiment, a vehicle charging station includes a power distribution interface, a receiver component, and an authorization component. The power distribution interface is configured to electrically couple with and provide electrical power to a power receiving interface of a vehicle. The power distribution interface includes a power cable extending from the vehicle charging station and the power cable includes an outlet plug. The receiver component is located within the power cable and is configured to receive identification information that uniquely identifies the vehicle from an identification component of the vehicle. The receiver component is positioned to align with the identification component to allow electrical communication between the identification component and the receiver component when the power receiving interface is electrically coupled to the power distribution interface.
