System and method for cooperatively operating a smart thermostat and vehicle to grid automobile
A system and method of managing the operation of a remotely controllable control unit for an appliance in a building during peak power demand hours with an application on a mobile device further in communication with a vehicle having a rechargeable battery capable of providing power to a power grid is disclosed. The application determines a state-of-charge of the rechargeable battery in the vehicle, and determines a location of the vehicle and whether the vehicle is within a threshold distance to the building. The building is preconditioned using the appliance to a preferred state if the vehicle is within the threshold distance to the building. When the vehicle arrives at the building, it is electrically connected to the power grid to provide electricity from the rechargeable battery to the power grid to replace the power used during the preconditioning.
1. A method of managing the operation of a remotely controllable control unit for an appliance in a building with an application on a mobile device further in communication with a vehicle having a rechargeable battery capable of providing power to a power grid, comprising the steps of:
determining a state-of-charge of the rechargeable battery in the vehicle;
determining a location of the vehicle;
determining whether the vehicle is within a threshold distance to the building;
preconditioning the building using the appliance to a preferred state if the vehicle is within the threshold distance to the building;
electrically connecting the vehicle to the power grid when the vehicle arrives at the building; and
providing electricity from the rechargeable battery to the power grid.
2. The method of claim 1 wherein the appliance is an air conditioner and the preferred state is a preferred temperature.
3. The method of claim 2 wherein the step of preconditioning the building further comprises the step of:
measuring a temperature in the building;
starting the air conditioner in the building;
stopping the air conditioner in the building when the temperature in the building is equal to the preferred temperature.
4. The method of claim 3 wherein the air conditioner is stopped prior to reaching the preferred temperature if the state-of-charge of the rechargeable battery is below a threshold level.
5. The method of claim 3 wherein the threshold level is a level of the state-of-charge equal to a level of electricity necessary to precondition the building.
6. The method of claim 3 wherein the air conditioner is not started if the temperature of the building is equal to or less than the preferred temperature of the building.
7. The method of claim 1 wherein the step of determining whether the vehicle is within a threshold distance to the building further comprises the steps of:
estimating a time to arrive at the building based on a calculated distance between a current location of the vehicle and the building based upon historical driving patterns of an user;
adjusting the time to arrive at the building further based on real-time traffic information; and
calculating the threshold distance to be a distance traversable in a calculated time to arrive at the building required to precondition the building.
8. The method of claim 1 wherein the mobile device is a telephone.
9. The method of claim 1 wherein the step of determining a location of the vehicle further comprises the step of:
calculating location based upon signals received from a global positioning satellite system.
10. The method of claim 1 wherein the step of determining a location of the vehicle further comprises the step of:
calculating location based upon signals received from a cellular telephone network.
11. A method of managing the operation of a remotely controllable thermostat for an air conditioner in a home with an application on a mobile device further in communication with a vehicle having a rechargeable battery capable of providing power to a power grid, comprising the steps of:
determining a state-of-charge of the rechargeable battery in the vehicle;
determining a location of the vehicle;
determining whether the vehicle is within a threshold distance to the home;
preconditioning the home using the air conditioner to a preferred temperature if the vehicle is within the threshold distance to the home;
electrically connecting the vehicle to the power grid when the vehicle arrives at the home; and
providing electricity from the rechargeable battery to the power grid to replace an amount of electricity used by the air conditioner to precondition the home.
12. The method of claim 11 wherein the step of preconditioning the home further comprises the step of:
measuring the temperature in the home;
starting the air conditioner in the home;
stopping the air conditioner in the home when the temperature in the home is equal to the preferred home temperature.
13. The method of claim 12 wherein the air conditioner is stopped prior to reaching the preferred temperature if the state of charge of the rechargeable battery is below a threshold level equal to a level of electricity necessary to precondition the home.
14. The method of claim 12 wherein the air conditioner is not started if the temperature of the home is equal to or less than the preferred temperature of the home.
