METHOD AND APPARATUS FOR ELECTRIC VEHICLE CHARGING STATION LOAD MANAGEMENT IN A RESIDENCE
First Claim
1. An electric vehicle charging station for charging electric vehicles to be installed in a residence, wherein the electric vehicle charging station is to be coupled through a main circuit breaker in an electrical service panel of the residence with a set of one or more service drop power lines that provide electricity from a power grid to the electric vehicle charging station, the electric vehicle charging station comprising:
- a charging point connection to couple an electric vehicle with the set of service drop power lines through an electrical circuit;
a current control device coupled with the charging point connection to control the amount of electric current that can be drawn from the set of service drop power lines by an electric vehicle through the charging point connection;
a receiver to receive energy readings from one or more current monitors that measure current flowing on one or more electrical circuits of the residence, wherein each received energy reading indicates that an amount of current is being drawn through the one or more electrical circuits from the set of service drop power lines separate and apart from current that is drawn through the charging point connection; and
a set of one or more control modules coupled with the receiver and the current control device, wherein the set of control modules are to cause the current control device to control the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings to avoid tripping the main circuit breaker.

Abstract
An electric vehicle charging station that is installed in a residence is coupled with a main circuit breaker in an electrical service panel. The charging station includes a charging point connection that couples an electric vehicle to a set of service drop power lines that provide electricity from a power grid to the residence; a current control device coupled to control the amount of electric current that can be drawn from the set of service drop power lines by an the electric vehicle through the charging point connection; a receiver to receive energy readings from one or more current monitors that indicate an amount of current is being drawn from the set of service drop power lines; and a set of control modules to cause the current control device to control the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings to avoid tripping the main circuit breaker.

22. A method in an electric vehicle charging station to assist in regulating electrical load management in a residence, wherein the electric vehicle charging station is coupled through a main circuit breaker in an electrical service panel of the residence with a set of one or more service drop power lines that provide electricity from a power grid to the electric vehicle charging station, the method comprising:
-
receiving a set of one or more energy readings from a set of one or more current monitors that each measure current flowing on one or more electrical circuits of the residence, wherein each received energy reading indicates that an amount of current is being drawn through the one or more electrical circuits from the set of service drop power lines separate and apart from any amount of current being drawn by an electric vehicle through the electric vehicle charging station; and controlling, based on the received set of energy readings, the amount of current that can be drawn by an electric vehicle through the electric vehicle charging station such that the main circuit breaker does not exceed its rated amount. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
