Efficient usage, storage, and sharing of energy in buildings, vehicles, and equipment

The invention describes a system for managing energy in buildings by using a backup battery to power heating, ventilation, and air conditioning (HVAC) components. This battery can be directly attached to an HVAC unit or be part of a modular system, storing energy when it's cheap or demand is low, and then using it during peak times to save costs or even supply power back to the grid. The claims specifically focus on integrating these batteries with individual HVAC units like chillers or furnaces, potentially distributed throughout a building.
