ISO 15118 is an international standard establishing a secure communication protocol between an electric vehicle (EV) and a charging station (EVSE) through the charging cable.
In North America, this standard supports advanced charging capabilities such as smart charging, Vehicle-to-Grid (V2G) integration, and dynamic energy management, enabling EVs to interact intelligently with the power grid. Built on a secure IP framework, ISO 15118 ensures reliable data exchange and interoperability between EVs and charging infrastructure.
By enabling automated authentication, optimized energy flows, and bidirectional charging, ISO 15118 plays a critical role in the development of connected and efficient EV ecosystems, benefiting both commercial fleets and individual EV drivers. Its adoption is growing across the U.S. and Canada as electric mobility expands.
