Vehicle-to-home (V2H) describes a bidirectional electric energy transfer interface concept that enables the onboard traction battery energy storage system of plug-in electric vehicles to supply electrical power for residential household loads through dedicated power conversion and interconnection hardware ^[1]. Under V2H operation modes, the electric vehicle functions as a mobile distributed energy resource that can provide backup power for domestic appliances and critical residential loads during grid outages, or support residential energy management and load shifting applications when the utility grid remains connected ^[2]. It defines the energy flow relationship between the electric vehicle battery system and residential premises; it is conceptually differentiated from vehicle-to-grid, whose primary objective is feeding power back to utility distribution networks at grid level rather than serving individual residential loads ^[3].
