International Organization for Standardization

A family of standards defining communication between electric vehicles and charging infrastructure, including Plug & Charge and bidirectional energy communication.

ISO 15118-1 defines common terms, actors, requirements, and charging or discharging use cases for the ISO 15118 family. It matters to V2X because it gives independently developed systems a common technical contract.

ISO 15118-2 defines first-generation high-level vehicle-to-charger network and application messages, including Plug & Charge. It matters to V2X because it gives independently developed systems a common technical contract.

ISO 15118-20 defines second-generation charging messages, including bidirectional power-transfer communication. It matters to V2X because it gives independently developed systems a common technical contract.

ISO 15118-8 defines wireless data-link communication between vehicles and charging equipment. It matters to V2X because it gives independently developed systems a common technical contract.

ISO 26262 defines a lifecycle framework for managing hazards caused by malfunctioning electrical and electronic vehicle systems. It matters to V2X because it gives independently developed systems a common technical contract.

ISO/SAE 21434 defines cybersecurity risk management across the lifecycle of road-vehicle electrical and electronic systems. It matters to V2X because it gives independently developed systems a common technical contract.

Plug & Charge enables a compatible electric vehicle and charging station to authenticate, authorize, and manage charging automatically through a secure digital connection.

Vehicle-to-Grid enables electric vehicles to exchange energy with the electric grid, allowing managed charging and, where supported, the export of stored vehicle energy.
