Embodiment 1

[0022] The invention proposes an electric vehicle charging station for charging an electric vehicle to be installed in a dwelling, wherein said electric vehicle charging station is connected to a set of one or Multiple connected, service power lines that provide power from the grid to EV charging stations, including:

[0023] a charging point connection for coupling the electric vehicle with the set of service step-down power lines via an electrical circuit;

[0024] a current control device connected to the charge point connection to control the amount of current that the electric vehicle draws from the set of service power lines through the charge point connection;

[0025] a receiver for receiving energy readings from one or more current monitors measuring current flowing on one or more electrical circuits of the dwelling, wherein each received energy reading indicates The amount of current drawn by one or more circuits. The service interruption power cord is separated an...

Embodiment 2

[0037] The present invention discloses a method of auxiliary regulating electrical load management in a dwelling in an electric vehicle charging station, wherein the electric vehicle charging station communicates with a set of one or a or more service power lines that provide power from the grid to electric vehicle charging stations, the method includes:

[0038] Receive a set of one or more energy readings from a set of one or more current monitors, each current monitor measuring the current flowing on one or more electrical circuits in the dwelling, where each received energy reading represents the current flowing through a Current draws a certain amount of current. One or more circuits from the set of service drop power lines are separated and separated from any amount of current drawn by the electric vehicle through the electric vehicle charging station; and

[0039] Based on the received set of energy readings, the amount of current that the electric vehicle can draw thr...

Abstract

The invention discloses anelectric vehicle charging station for charging an electric vehicle to be installed in a house.The electric vehicle charging station is connected to a set of one or moreservice power cords providing power from a power grid to the electric vehicle charging station through a main circuit breaker in an electrical service panel of the house.. According to the electric vehiclecharging station disclosed by the invention, the charging reliability is greatly improved.

Description

technical field [0001] The invention relates to the charging field, in particular to an electric vehicle charging station. Background technique [0002] Electric vehicles include power storage devices that must be recharged periodically. These electric vehicles are often charged at home. These electric vehicles can usually be charged using a standard household outlet. However, it can take several hours to fully charge an electric vehicle using a standard household socket. [0003] Electric vehicle charging stations can be used to charge electric vehicles at a much faster rate than using a typical standard household outlet. These charging stations are often hardwired directly to the power lines that power the residence. While these charging stations charge electric vehicles faster than using a standard household outlet, they also draw a greater amount of current while charging an electric vehicle than using a standard household outlet. [0004] Dwellings have a finite el...
