Abstract: An adaptive electric vehicle supply equipment (EVSE) unit provides intelligent control to vary the EVSE load placed upon the local electric connection based upon real time load measurements of both the overall premises load and the specific capacities and requirements of the EVSE. The EVSE unit includes a current power transformer at the main service entry point to capture real time power level at the meter. Additional real time current measurements are available within unit to measure the real time output power on the AC legs going to a vehicle. The unit is configured to a controller module which measure and controls the pilot signal output based on a comparison of the power level at the meter with the power level at the EVSE unit against the desired or required power output to the vehicle.

Abstract: A power generation allocation and measurement device has an inverter assignment matrix fed by one or more inverter load controllers, the controllers connected to respective inverters. The device includes multiple unit controllers associated with respective metered distribution panels of a multi-unit or multi-panel power installation. A group controller is in communication with each unit controller and the inverter assignment matrix. The device is fed by a power generator such as a photovoltaic panel. The device allocates power to the metered distribution panels via the group controller, based on feedback from the discrete unit controllers.

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.

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.

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.
