Abstract

Apparatuses including utility meter, power electronics, and communications circuitry are provided. The utility meter circuitry is configured to measure usage of electricity supplied by an electric utility to a premise of a customer of the electric utility. The power electronics circuitry is configured to regulate a voltage level supplied to the premise of the customer. Moreover, the communications circuitry is configured to provide communications with a first electronic device of the customer at the premise of the customer and to provide communications with a second electronic device that is upstream from the apparatus. Related methods of operating an apparatus including utility meter, power electronics, and communications circuitry are also provided.

First claim

What is claimed is:

1. A premise energy router comprising:
electric utility meter circuitry in the premise energy router and configured to measure usage of electricity supplied by an electric utility to a premise of a customer of the electric utility;
power electronics circuitry in the premise energy router and configured to regulate a voltage level supplied to the premise of the customer; and
communications circuitry in the premise energy router and configured to provide communications with a first electronic device of the customer at the premise of the customer and to provide communications with a second electronic device that is upstream from the premise energy router,
wherein the premise energy router is no larger than twenty inches wide, twelve inches deep, and twenty-four inches long,
wherein a utility secondary service connection of the electric utility is input to the premise energy router, and
wherein the premise energy router is connected to a wiring connection of the customer at the premise of the customer.

2. The premise energy router of claim 1 ,
wherein the voltage level that the power electronics circuitry is configured to regulate comprises 120 Volts and/or 240 Volts, and
wherein the premise energy router is mountable on a side of the premise of the customer.

3. The premise energy router of claim 2 , wherein the electric utility meter circuitry is configured to operate with a load from the premise of the customer between 0 Volt-Amperes and 15,000 Volt-Amperes.

4. The premise energy router of claim 1 , wherein the power electronics circuitry comprises a Direct Current (DC) bus configured to interface with a DC load and/or a DC power source at the premise of the customer.

5. The premise energy router of claim 4 ,
wherein the power electronics circuitry comprises power inverter circuitry that is configured to convert DC power received from the DC power source via the DC bus into Alternating Current (AC) power, and
wherein the DC bus comprises a 400-Volt DC input port or higher.

6. The premise energy router of claim 4 ,
wherein the DC bus comprises a DC output port of a 400-Volt or higher DC power source that is configured to provide DC power to the DC load, and
wherein the power electronics circuitry comprises power inverter circuitry that is configured to convert Alternating Current (AC) power into DC power for the DC output port.

7. The premise energy router of claim 1 , wherein the communications circuitry comprises:
a first communications interface configured to provide first communications with the first electronic device of the customer; and
a second communications interface configured to provide second communications with the second electronic device that is upstream from the premise energy router.

8. The premise energy router of claim 1 ,
wherein the power electronics circuitry is configured to adjust the voltage level by up to +/−10%,
wherein the premise energy router is spaced apart from a distribution transformer that serves the premise of the customer, and
wherein the power electronics circuitry is configured to automatically hold the voltage level constant as long as the voltage level is within up to +/−10% of an incoming voltage from the distribution transformer.

9. The premise energy router of claim 8 , wherein the voltage level is derived from a user input that is provided to the premise energy router remotely via the communications circuitry.

10. The premise energy router of claim 1 , further comprising bypass circuitry in the premise energy router and configured to bypass the power electronics circuitry and the communications circuitry, wherein the premise energy router is spaced apart from a circuit breaker box.

11. The premise energy router of claim 1 , wherein the power electronics circuitry is configured to hold the voltage level within a predetermined voltage range.

12. The premise energy router of claim 1 , further comprising a bus bar that is in the premise energy router and is connected to the electric utility meter circuitry and to the power electronics circuitry,
wherein the electric utility meter circuitry and the power electronics circuitry are downstream from the bus bar, and
wherein the bus bar is downstream from a distribution transformer that serves the premise of the customer.

13. The premise energy router of claim 1 , wherein the electric utility meter circuitry, the power electronics circuitry, and/or the communications circuitry comprise integrated circuits on respective plug-and-play cards in the premise energy router.

14. A method of operating a premise energy router connected between a utility secondary service of an electric utility and a wiring connection of a customer at a premise of the customer, the method comprising:
measuring, using electric utility meter circuitry of the premise energy router connected between the utility secondary service of the electric utility and the wiring connection of the customer at the premise of the customer, usage of electricity supplied by the electric utility to the premise of the customer of the electric utility;
regulating, using power electronics circuitry of the premise energy router connected between the utility secondary service of the electric utility and the wiring connection of the customer at the premise of the customer, a voltage level supplied to the premise of the customer; and
providing communications, using communications circuitry of the premise energy router connected between the utility secondary service of the electric utility and the wiring connection of the customer at the premise of the customer, with a first electronic device of the customer that is at the premise of the customer and with a second electronic device that is upstream from the premise energy router connected between the utility secondary service of the electric utility and the wiring connection of the customer at the premise of the customer.

15. The method of claim 14 , wherein providing the communications comprises:
providing first communications, via a first communications interface, with the first electronic device of the customer; and
providing second communications, via a second communications interface, with the second electronic device that is upstream from the premise energy router connected between the utility secondary service of the electric utility and the wiring connection of the customer at the premise of the customer.

16. The method of claim 14 , further comprising:
receiving, via the communications circuitry, a user input providing a command to hold the voltage level constant,
wherein the power electronics circuitry is downstream from a distribution transformer that serves the premise of the customer,
wherein the distribution transformer is downstream from a substation of the electric utility, and
wherein regulating the voltage level comprises holding the voltage level constant as long as the voltage level is within up to +/−10% of an incoming voltage from the distribution transformer, in response to receiving the user input.

17. The method of claim 14 , further comprising:
receiving, via the communications circuitry, a user input providing a command to hold the voltage level within a predetermined voltage range,
wherein the power electronics circuitry is downstream from a distribution transformer that serves the premise of the customer,
