ISO 15118 Insights

What is ISO 15118?

ISO 15118 is an international standard defining a communication protocol for electric vehicle (EV) charging. It specifies the communication between the EV and the charging station (EVSE - Electric Vehicle Supply Equipment), enabling features like Plug & Charge (automatic authentication and authorization), smart charging (optimizing charging based on grid conditions or user preferences), bidirectional charging (vehicle-to-grid, V2G), and secure data exchange.
