Abstract:
An energy management system includes a local power grid configured to route electricity, the local power grid configured to receive electricity from a municipal power grid of a utility service provider; an electric appliance electrically coupled to the local power grid, the electric appliance configured to receive electricity from the local power grid for operating according to an energy usage state; an electric vehicle electrically coupleable to the local power grid, the electric vehicle configured to exchange electricity with the local power grid; and a system server communicatively coupled to the electric appliance and the electric vehicle. The system server configured to: receive utility related data, appliance related data, and vehicle related data, determine, based on the received data, a vehicle-to-grid energy cost and a utility energy cost, and control the electric vehicle to discharge electric energy to the local power grid for operating the electric appliance, based on a comparison of the vehicle-to-grid energy cost with the utility energy cost for operating the electric appliance according to the energy usage state.
