Overview
IEC 63380-2:2025 - Standard interface for connecting charging stations to local energy management systems (Part 2: Specific data model mapping) defines how local energy management systems (EMS) and electric vehicle (EV) charging station controllers exchange information securely via a resource manager. This part maps the high‑level use case functions from IEC 63380-1 to concrete data models, specifically SPINE Resources and ECHONET Lite Resources, enabling interoperable, machine‑readable communications between EMS and charging station controllers.
Key Topics
- Scope and Purpose: Specifies secure information exchange and the mapping of generic use case functions (UCFs) to specific resource/data model representations.
- Data Model Mapping: Detailed mappings of UCFs (e.g., Measurement, Device State, Charging Power Limits, Setpoint, Session Summary, Load Control, Manufacturer Information) to SPINE and ECHONET Lite resources.
- Interaction Diagrams: Includes hierarchy, sequence and binding diagrams to illustrate discovery, subscription, request/response and notification flows.
- Resource Manager Pattern: Describes how EMS communicate with charging station controllers via a resource manager, standardizing discovery, read/write, and subscription mechanisms.
- Security & Interoperability Focus: Emphasizes secure information exchange and consistent semantics to support interoperable EV charging infrastructures.
- Extensive UCF Coverage: The document enumerates and maps many UCFs (e.g., UCF_Measurement, UCF_Device_Configuration, UCF_Power_Limit, UCF_Load_Control), providing practical templates for implementation.
Applications
IEC 63380-2:2025 is intended for anyone implementing or integrating EV charging and local energy management solutions:
- Charging station manufacturers - implement standard resource representations (SPINE / ECHONET Lite) to ensure compatibility with EMS.
- EMS and building energy integrators - map EMS functions to charging station controls for demand response, load balancing and energy optimization.
- Software developers & system integrators - develop middleware, resource managers and APIs that conform to the specified mappings and message flows.
- Utilities and operators - enable standardized control and telemetry for fleet charging, grid-friendly charging schedules and local congestion management.
- Test labs and certification bodies - validate interoperability and conformance using the sequence diagrams and resource definitions provided.
Related Standards
- IEC 63380-1 - defines the generic use case functions (UCFs) that IEC 63380-2 maps to concrete data models.
- SPINE and ECHONET Lite specifications - used as the target resource/data models in this part and relevant for implementers.
By standardizing data model mappings and communication sequences, IEC 63380-2:2025 accelerates interoperable, secure EV charging integration with local energy management systems, enabling scalable, grid‑aware charging deployments.
