Overview
IEC 63380-1:2025 is an international standard published by the International Electrotechnical Commission (IEC) that establishes a secure and standardized interface for connecting electric vehicle (EV) charging stations to local energy management systems (EMS). This first part of the standard focused on general requirements, use cases, and abstract messaging aims to harmonize communication between charging station controllers and EMS via a resource manager. It defines the sequences of information exchange and generic data models necessary for effective, interoperable, and secure EV charging management.
By addressing scenarios related to charging coordination, energy consumption monitoring, and power optimization, IEC 63380-1:2025 facilitates the integration of EV charging infrastructure into local energy grids, promoting efficient energy use and grid stability.
