Load control system that operates in an energy-savings mode when an electric vehicle charger is charging a vehicle

摘要

A load control system for a building having a lighting load, a window, a heating and cooling system, and an electric vehicle charger for charging a vehicle (e.g., an electric or hybrid vehicle) operates in an energy-savings mode to reduce the total power consumption of the load control system when the vehicle charger is presently charging the vehicle. The load control system may comprise a lighting control device for controlling the intensity of the lighting load, a daylight control device for adjusting the amount of natural light admitted through the window, and a temperature control device for controlling a setpoint temperature of the heating and cooling system to thus control a present temperature in the building. When the vehicle charger is presently charging the vehicle, the load control system automatically controls the lighting control device, the daylight control device, and the temperature control device to decrease the total power consumption of the load control system.

主权项

1. A load control system for a building having a lighting load located in a space of the building, a heating and cooling system, and a window located in the space of the building, the load control system comprising:
an electric vehicle charger for charging a vehicle; a lighting control device for controlling the amount of power delivered to the lighting load, the lighting control device operable to automatically decrease the amount of power delivered to the lighting load when the electric vehicle charger is presently charging the vehicle; a daylight control device for controlling the amount of natural light to be admitted through the window, the daylight control device operable to automatically adjust the amount of natural light admitted through the window when the electric vehicle charger is presently charging the vehicle so as to decrease the power consumption of the heating and cooling system; and a temperature control device for controlling a setpoint temperature of the heating and cooling system to thus control a present temperature in the building, the temperature control device operable to automatically adjust the setpoint temperature of the heating and cooling system when the electric vehicle charger is presently charging the vehicle so as to decrease the power consumption of the heating and cooling system.
