Abstract

Interconnection meter socket adapters are provided. An interconnection meter socket adapter comprises a housing enclosing a set of electrical connections. The interconnection meter socket adapter may be configured to be coupled to a standard distribution panel and a standard electric meter, thereby establishing connections between a distribution panel and a user such that electrical power may be delivered to the user while an electrical meter measures the power consumption of the user. A power regulation module is disposed between the interconnection meter socket adapter, and configured to selectively connect one or more energy sources or energy sinks.

Claims

1. A method of managing power consumption by an electrical vehicle through an interconnect socket adapter, comprising:

measuring, by a measurement module of a power regulation module, a user load power consumption amount consumed by a plurality of user loads;

measuring, by the measurement module, an electrical vehicle power consumption amount consumed by the electrical vehicle connected to the power regulation module of the interconnect socket adapter;

determining, by the measurement module, a threshold power consumption value; and

comparing an overall power consumption amount with the determined threshold power consumption value;

wherein, if the overall power consumption amount exceeds the threshold power consumption value, reducing the overall power consumption;

wherein determining the threshold power consumption comprises;

identifying a panel rating from a meter to which the interconnect socket adapter is connected; and

calculating a threshold power consumption value comprising a power amount within 70% and 90% of the panel rating.

2. The method of claim 1, wherein the measurement module comprises a voltage meter.

3. The method of claim 1, wherein the measurement module comprises a communications module comprising electronic circuitry configured to enable wireless communication.

4. The method of claim 1, wherein the power regulation module comprises a disconnect switch.

5. The method of claim 4, reducing overall power consumption comprising disconnecting the electrical vehicle such that the electrical vehicle no longer consumes electrical power.

6. The method of claim 1, wherein the power regulation module comprises a current limiter.

7. The method of claim 6, reducing overall power consumption comprising limiting, by the current limiter, an amount of electrical power available to the electrical vehicle connected to the power regulation module.

8. The method of claim 1, wherein the threshold power consumption value comprises a power amount about 80% of the panel rating.
