Why is OCPP 1.6/2.0 protocol compatibility considered the "invisible passport" for charging pile control boards going global?

The reason why "OCPP 1.6/2.0 Protocol Compatibility" is referred to as the "invisible passport" for charging pile control boards to go global lies in its transformation of "technical language" into a "market pass." Without it, charging piles cannot connect to other networks; with it, they can plug and play seamlessly with any OCPP backend worldwide. Its specific value is reflected in four key logical principles:

Regulatory mandates: The EU's AFIR, the UK's EVHS, and California's CEC all require "support for OCPP" as a prerequisite for grid connection or subsidies

• Starting in 2025, newly installed public charging stations in California must support OCPP 2.0.1 or risk being denied construction permits;

• The EU Alternative Fuels Infrastructure Regulation (AFIR) requires public charging networks to be "open, transparent, and interoperable," with OCPP directly cited as the technical implementation pathway.

If the control panel is natively compatible with OCPP, the OCA test report can be directly reused during CE/UKCA certification, saving 6–8 weeks in the verification process.

1.nteroperable Tickets: Breaking the "Private Protocol Lock-in" to Enable Operators to Buy, Swap, and Expand Confidently

• Overseas operators (such as Shell and Ionity) uniformly adopt OCPP 1.6J or 2.0.1 as the backend standard, with "native OCPP" accounting for 15% of the technical scoring in tender evaluations;

• For charging piles using proprietary protocols, the entire batch of hardware becomes obsolete once the backend manufacturer discontinues support. In contrast, OCPP-compliant piles can switch platforms at any time, increasing residual value by 30%.

For control board manufacturers, "OCPP compatibility" means directly obtaining the operator's "whitelist" without the need for secondary interface development.

2.Function "No-Sign"：Remote Start/Stop, Billing, OTA, Fault Reporting "Ready-to-Use Out of the Box"

• OCPP defines over 50 messages such as RemoteStartTransaction, MeterValues, and SignedFirmwareUpdate, eliminating the need for the mainboard firmware to implement private fields;

• During roaming and clearing on overseas platforms (such as Hubject and Gireve), only OCPP standard fields are recognized, while private fields are discarded.

After transplanting the OCPP stack onto the control board, a single development effort can simultaneously support backends in Europe, North America, and Southeast Asia, eliminating the need for "one version per country.".

3.Certification "Seal": OCA Official Testing = Global Interoperability "Graduation Certificate"

• Only about 20 companies worldwide have passed the full OCPP 2.0.1 certification, with three currently in China (including Daotong), and passing this test is considered a "stamp of technical strength.";

• The certification can be directly incorporated into the CE technical documentation of TÜV/DEKRA, reducing third-party interoperability testing costs by 30%.

summary

In the process of going abroad, OCPP compatibility is not written on the front of the certificate like safety regulations and EMC, but it determines whether the pile can be "globally connected" - it is an invisible passport: without it, the product will be blocked by a "technical visa" at the port; With it, the control board can be plug and play in any OCPP backend worldwide, saving on development, certification, and maintenance, and can be directly exchanged for orders and premiums.
