IEC 63584-201:2026 – Open Charge Point Protocol 2.01

IEC 63584-201:2026 defines the Open Charge Point Protocol (OCPP) 2.0.1, the communication protocol linking a Charging Station with a Charging Station Management System (CSMS). As a second edition replacing the 2024 publication, it consolidates member feedback, certification-program experience, and structural refinements into a single technical reference for the electric vehicle charging industry.

Standard Information

IEC 63584-201:2026, published on 18 September 2026, specifies the Open Charge Point Protocol (OCPP) 2.0.1 for communication between a Charging Station and a Charging Station Management System. Developed by technical committee TC 69, it entered circulation as a Fast-Track document and replaces the earlier 2024 edition of IEC 63584. The following record summarizes its bibliographic identity. - Designation: IEC 63584-201:2026
- Full title: Open Charge Point Protocol 2.01
- Status: Current
- Publication date: 2026-09-18
- ICS classification: 43, 43.120
- Technical committee: TC 69

Scope and Application

The protocol covers the message exchange between a Charging Station and a Charging Station Management System. A CSMS is the central software platform that monitors charging infrastructure, while the Charging Station is the field-side equipment delivering energy to electric vehicles. The standard defines how these two endpoints communicate so that stations from different suppliers can interoperate with a common management system. Its protocol architecture accommodates any type of charging technique. This technology-neutral framing means the communication layer does not restrict itself to one charging mode, connector arrangement, or power-delivery approach. Implementers can therefore apply the same protocol across direct-current fast charging, alternating-current charging, and other configurations without protocol-level divergence. The document is based on OCPP 2.0.1 and was submitted through the Fast-Track route, which transfers an established industry specification into the IEC framework with limited editorial change. Procurement teams and quality managers should note that this second edition cancels and replaces IEC 63584 published in 2024 and constitutes a technical revision, not a mere republication.

Products and Materials Covered

The equipment families within scope fall under ICS classifications 43 and 43.120, the international class for electrically propelled road vehicles. The primary objects are Charging Stations — the physical units installed at public, fleet, workplace, or residential locations — together with the CSMS software that manages them. The standard governs the communication interface between these two product categories rather than the hardware construction of either. Because the protocol accommodates any charging technique, products in scope span stations regardless of their charging method or rated output philosophy. Conformity work therefore concentrates on the protocol implementation: message formats, sequence behavior, and functional exchanges between station and management system. Mechanical, electrical safety, and EMC characteristics of the station fall outside this document and belong to other areas of standardization.

Testing and Compliance Considerations

Conformity assessment for a communication protocol standard typically proceeds through type testing at an accredited laboratory. The laboratory exercises the Charging Station implementation against a reference CSMS or test harness, observing whether the message sequences and functional behaviors follow the documented test cases. Evidence is captured in traceable logs, and the resulting report documents the configuration under test, including hardware and software versions. Acceptance verification often supplements type testing. Buyers and network operators may run their own interoperability sessions before deploying stations on live networks, confirming that a certified product behaves correctly against their specific CSMS implementation. Documentation review — protocol conformance statements, test reports, and version records — forms part of routine supplier qualification. Retest triggers deserve attention with this edition in particular. Because IEC 63584-201:2026 introduces clarifications to requirements, use cases, and sequence diagrams, plus revised test-case descriptions in its part 6, organizations holding conformity evidence against the 2024 edition should assess whether those changes affect their results. Software updates that alter protocol behavior, or the renaming of "OCTT" references to "Test System" in parts 5 and 6, may also prompt documentation updates. A gap assessment against the listed technical changes is the customary first step before commissioning new testing.

Related Standards and Series Context

The designation itself carries structural information. The number 63584 identifies the standard series; the suffix -201 indicates a part within that numbering scheme, and the trailing :2026 marks the edition year. Readers comparing documents should distinguish between the part number and the year suffix, since both govern which text applies at a given time. This is a second edition, as stated in the abstract, and it cancels and replaces the 2024 publication of the base document. The edition structure signals a living standard maintained through technical revisions driven by member feedback, task-group meetings, and an active certification program. Anyone citing the standard in specifications or purchase documents should reference the full designation with year, IEC 63584-201:2026, to avoid ambiguity with the replaced edition.
