ISO 15118 (Road vehicles — Vehicle to Grid Communication Interface)

ISO standard 15118 defines a digital communication protocol that enables the secure exchange of information between an EV and a charging station. ISO15118 supports four use cases: Plug&Charge (PnC), smart charging, bi-directional charging, and wireless charging. The ISO 15118 PnC use case enables an EV driver to charge an EV without requiring the driver to interact with the charging station, eliminating the need for the EV driver to pay using a card or app. The driver simply plugs in and charging begins.
