The Open Charge Alliance (OCA) announced on October 12, 2026 that conformance testing for OCPP 2.1 is now available in its OCTT Professional test tool. The release follows the IEC’s publication on September 22, 2026 of IEC 63584-210:2026, the second edition of the international standard based on OCPP 2.1. Together, the two steps give charger and back-office developers a formal specification and a test route for features such as ISO 15118-20 support and bidirectional power transfer.
Key Takeaways
- OCPP 2.1 conformance testing is now available in OCTT Professional.
- IEC 63584-210:2026 adds certification profiles and test cases for OCPP 2.1.
- V2X, DER control and ISO 15118-20 functions can now be tested before certification.
- Buyers should request version-specific test evidence, not just protocol claims.
Key Facts
| Item | Detail |
|---|---|
| OCTT Professional | Now tests OCPP 1.6, OCPP 2.0.1 and OCPP 2.1 |
| New testable OCPP 2.1 features | ISO 15118-20 support, bidirectional power transfer, improved smart charging |
| IEC 63584-210:2026 (OCPP 2.1) | Edition 2.0, published 2026-09-22 |
| IEC 63584-201:2026 (OCPP 2.0.1) | Published 2026-09-18, replacing IEC 63584:2024 |
What Changed in the Standard
According to the IEC, the second edition of IEC 63584-210 is a technical revision. It adds parts 5 and 6 with the certification profiles and test cases, resolves issues and adds clarifications mostly related to the new OCPP 2.1 features such as DER control, V2X and ISO 15118-20, and folds in all OCPP 2.0.1 errata, since the two versions are backwards-compatible. The parallel OCPP 2.0.1 standard, IEC 63584-201, adds clarifications to requirements and use cases and restructures its test case descriptions.
The OCA says the test tool milestone was reached with its Golden System Under Test partners, who helped validate the new capabilities, and that OCTT Professional helps manufacturers find issues and prepare for certification.
What It Means
For charge point operators, OCPP 2.1 testing makes it realistic to put smart charging and V2X functions into procurement specifications with test evidence behind them. Buyers should ask suppliers which OCPP version and which functional blocks are certified, and for which firmware version. A charger that says “OCPP 2.1 ready” without a test report is still a promise.
Many installed fleets will run OCPP 1.6J for years, and that remains a workable baseline for scheduling and remote monitoring. EVDANCE’s EV-AC03201T dual-connector AC station and EV-RHDC30K-L DC charger support OCPP 1.6J; brands planning newer protocol versions can discuss firmware roadmaps through our OEM program.
