Abstract

A method for determining a power source using a digital breakout box between a first and a second power source to power a plurality of circuits by setting at least one first and a second limit, determining the state of charge of the power source, determining an available discharge energy, and classifying each circuit into categories. When the second power source is de-energized, the circuits to be powered by the first power source are determined by comparing the available discharge energy with the first and second limits. When the second power source is powered, the circuits to be powered by the first power source and the circuits to be powered by the second power source are determined by comparing the current state of charge with the first and second limits.

Description

INTRODUCTION The present disclosure relates generally to wallbox units and in particular to systems and methods for individual adaptation and management which circuits receive power from an external power source by means of a digital break-out box. Breakout boxes are located in buildings, including homes and offices, and connect one or more power sources to one or more circuits connected to the building. The power source typically includes the electrical grid and its associated infrastructure. However, with the advent of electric vehicles, it is possible to connect an electric vehicle with a battery to the building via the breakout box. Using the electric vehicle as a separate power source by connecting it to a breakout box allows the building to be powered during a grid outage. Although wallbox units fulfill their intended purpose, there is a need for a new and improved system and procedure for individually adapting a configuration of electrical loads based on user optimization and other extrinsic factors. SUMMARY A method for individually adjusting a multitude of circuits connected to a first and a second power source using a digital breakout box is provided according to several aspects. The method can include determining the state of the second power source, which may be one of the following: a powered state or a de-energized state. The second power source is considered to be powered when the digital breakout box is drawing power from the second power source. The second power source is considered to be de-energized when the digital breakout box is not drawing power from the second power source. If the state is de-energized, the method can further include determining the first power source. If the state is de-energized, the method can further include determining the current state of charge of the first power source. If the state is de-energized, the method can further include setting at least one first discharge limit and one second discharge limit of the first power source. If the state is de-energized, the method may further include classifying the circuits of the plurality of circuits into at least a first category and a second category. If the state is de-energized, the method may further include determining a maximum energy requirement based on the current consumed by the plurality of circuits over a specific period. If the state is de-energized, the method may further include determining a minimum energy requirement based on the current consumed by the plurality of circuits in the first category over the same period. If the state is de-energized, the method may further include determining an available discharge energy based on the sum of the individual limit values subtracted from the current state of charge, multiplied by a battery energy capacity. If the state is the no-current state, the procedure may further include comparing the available discharge energy with the first discharge limit and the second discharge limit to determine which of the plurality of circuits is powered by the first energy source when the available discharge energy is less than the minimum energy requirement and the available discharge energy is greater than the maximum energy requirement. In another aspect of the present disclosure, setting the first discharge limit and the second discharge limit may further comprise setting the first discharge limit to a first calibrated value based on the discharge energy and setting the second discharge limit to a second calibrated value based on the discharge energy, wherein the first calibrated value is greater than the second calibrated value. In another aspect of the present disclosure, classifying the circuits of the plurality of circuits into at least a first category and a second category may further include classifying the circuits of the plurality of circuits into the first category based on the arbitrary preferences of a user and classifying the circuits of the plurality of circuits into the second category based on the arbitrary preferences of the user. In another aspect of the present disclosure, the determination of the maximum energy requirement may further involve taking the total value of the current consumed by the plurality of circuits in the first category. and the total value is multiplied by a calibrated time value. In another aspect of the present disclosure, the determination of the maximum energy requirement may further include the greater of the two values: the power consumed by the multitude of circuits in the first category multiplied by a storm duration and the power consumed by the multitude of circuits in the first category multiplied by a power outage duration. In another aspect of the present disclosure, the determination of the minimum energy requirement may further involve taking the total amount of current consumed by the plurality of circuits in the second category and multiplying the total value by a calibrated time value.
