Abstract
A load control receiver includes a utility connection, a charging connection, and a relay controlling the supply of power from the utility connection to the charging connection. The load control receiver can be controlled in response to periods of low or high demand to control the availability and/or speed of charging based on demand response signals. A notification system can provide invitations to charge during periods of low demand, and the load control receivers can offer subsidized energy at particular times to users based on such invitations.
Claims20
A load control receiver for an electric vehicle charging system, comprising:
- a utility power connection configured to receive power;
- a charging connection configured to supply power to an electric vehicle charger;
- a relay configured to control supply of power to the charging connection;
- a wireless communication modem;
- and
- a controller configured to receive a demand response signal by way of the wireless communication modem and control the relay to control a quantity of power supplied to the charging connection based on the demand response signal.
A method for controlling electric vehicle charging, comprising:
- determining a demand condition based on a demand for power for a utility grid;
- when the demand condition exceeds a threshold, issuing a demand response signal to a plurality of load control receivers connected to the grid,
- wherein one or more load control receivers of the plurality of load control receivers control a respective relay to reduce a quantity of power provided to a respective electric vehicle charger connected to said load control receiver based on receiving the demand response signal.
A system for controlling electrical vehicle charging, comprising:
- a plurality of charging systems;
- and
- a utility enterprise system configured to:
- determine a demand condition for a utility grid;
- and
- based on the demand condition, issue a demand response signal to the plurality of charging systems,
- wherein each of the plurality of charging systems includes:
- a utility power connection configured to receive power from the utility grid;
- a charging connection configured to supply power to an electric vehicle charger;
- a relay configured to control supply of power to the charging connection;
- and
- a controller configured to receive the demand response signal and control the relay based on the demand response signal.
