Abstract

The present invention relates to a system having a building control system with a vehicle battery controller. The vehicle battery controller may be configured to control a vehicle battery charge and a vehicle battery discharge of a vehicle having a vehicle battery coupled to an electrical system of a building.

Claims

1. A system, comprising:

a building control system, comprising;

a vehicle battery controller configured to control a vehicle battery charge and/or a vehicle battery discharge of a vehicle having a vehicle battery coupled to an electrical system of a building.

2. The system of claim 1, wherein the vehicle battery controller comprises a fleet control configured to control charging and discharging of a fleet of vehicles having vehicle batteries coupled to the electrical system of the building.

3. The system of claim 1, wherein the vehicle battery controller is configured to enable the vehicle battery charge during a first period of low demand on a power utility and enable the vehicle battery discharge during a second period of high demand on the power utility.

4. The system of claim 1, wherein the vehicle battery controller is configured to enable the vehicle battery discharge to provide battery power to the electrical system of the building during a power shortage or a power outage.

5. The system of claim 1, wherein the vehicle battery controller is configured to enable the vehicle battery discharge in response to a spike in electrical demand in the building, or enable the vehicle battery charge in response to a dip in electrical demand in the building, or a combination thereof.

6. The system of claim 1, wherein the vehicle battery controller is configured to control the vehicle battery charge and/or the vehicle battery discharge based on building energy demand, a building energy control scheme, or a control signal independent of a power utility.

7. The system of claim 1, wherein the building control system comprises an electricity buying/selling feature based on real time pricing of electricity.

8. The system of claim 1, wherein the building control system comprises a carbon counter configured to provide an indication of carbon generated or deferred by the building to facilitate selection of energy sources for use by the building control system.

9. The system of claim 1, wherein the building control system comprises a stationary battery controller configured to control a stationary battery charge and a stationary battery discharge of a stationary battery coupled to the electrical system of the building.

10. The system of claim 1, wherein the building control system comprises a distributed energy controller configured to control a distributed energy source coupled to the electrical system of the building.

11. The system of claim 1, wherein the distributed energy source comprises a wind turbine, a solar panel, momentum, thermal, hydro or a combination thereof.

12. The system of claim 1, wherein the building control system comprises an air conditioner control, a furnace control, a water heater control, a pool pump control, a lighting control, a refrigerator control, a freezer control, a security system control, an air handler control, a chiller control, a pump control, a boiler control, or a combination thereof.

13. A system, comprising:

a building control system, comprising;

an energy controller configured to vary usage of grid power from a power utility and battery power from a battery in response to real time pricing of grid power.

14. The system of claim 13, wherein the energy controller comprises a vehicle battery controller configured to control a vehicle battery charge and a vehicle battery discharge of a vehicle in response to the real time pricing of grid power.

15. The system of claim 13, wherein the energy controller comprises an electricity buying/selling feature based on the real time pricing of grid power.

16. The system of claim 13, wherein the energy controller comprises a vehicle battery controller, a stationary battery controller, a wind power controller, a solar power controller, and a power grid controller.

17. The system of claim 13, wherein the energy controller comprises a building load controller configured to control lighting, heating, air conditioning, and security in the building in response to real time pricing of grid power.

18. A system, comprising:

a control panel, comprising;

a demand response controller configured to receive a demand response control signal from a power utility; and

a vehicle battery controller configured to control a vehicle battery charge and a vehicle battery discharge of a vehicle having a vehicle battery based on the demand response control signal from the power utility.

19. The system of claim 18, wherein the vehicle battery controller is configured to enable the vehicle battery charge during a first period of low demand on a power utility and enable the vehicle battery discharge during a second period of high demand on the power utility.

20. The system of claim 18, wherein the control panel comprises a home energy mangement system, a building management system, a vehicle control system, or a combination thereof.
