Abstract
An energy coupling method for household energy storage includes: connecting an alternate current (AC) output from an electric vehicle (EV) to a household electricity grid through an AC-to-AC power converter capable of outputting a vehicle-to-load (V2L) AC power that is synchronized to the household electricity grid; in response to an outage of an electricity grid that supplies power to the household grid, turning on the AC-to-AC power converter to supply the V2L AC power to a household load connected to the household electricity grid; and in response to a recovery of the electricity grid, turning off the AC-to-AC power converter to stop outputting the V2L AC power.
