Energy in electric vehicle batteries can be used for multiple purposes and are generally defined as V2X applications. Specifically, power stored in the batteries can be sold to the Grid in V2G (vehicle to Grid) function. Alternatively, power can be obtained from EV batteries for emergency household use in V2H (vehicle to home) function. Besides, the easy and efficient power transfer capability of the charger makes it a vital node in realizing smart grid, small grid, energy storage system, and more.
