Method and apparatus for management of current load to an electric vehicle charging station in a residence

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 an 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 attached to one or more electrical circuits of the residence that measure current flowing on the one or more electrical circuits of the residence with the exclusion of the electrical circuit providing current to the electrical vehicle charging station, wherein the receiver receives an energy reading from a corresponding current monitor that only transmits the energy reading to the receiver responsive to the corresponding current monitor measuring an amount of current flowing through a corresponding electrical circuit over a first threshold amount, wherein the amounts from the one or more current monitors are separate and apart from an amount of current that is drawn through the charging point connection coupling the electric vehicle with the set of service drop power lines;
• 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 limit the amount of current that can be drawn by the electric vehicle through the charging point connection based on the received energy readings for a limited amount of time upon receipt of the energy readings to avoid tripping the main circuit breaker, and wherein the set of control modules are further to cause the current control device to not limit the amount of current that can be drawn by the electric vehicle through the charging point connection in response to absence of receipt of the energy readings for greater than the limited amount of time.
