OCPI Data Exchange for National Access Points under AFIR

Under Regulation (EU) 2023/1804 (the Alternative Fuels Infrastructure Regulation, AFIR,) [1] and its Implementing
Regulation (EU) 2025/655 [2], operators of publicly accessible recharging and refuelling points for alternative fuels — or, by arrangement, the owners of those points — must make static and dynamic data available free of chargethrough the National Access Points (NAPs). This data must be open and accessible on a non-discriminatory basis to
any data user, and its format, update frequency, and quality are standardised so that data users receive reliable information.

The OCPI NAP extension aims to support:

• CPOs to use a unified way to share data with National NAPs.
• NAPs to get via a unified way the required data in line with the AFIR requirements and related delegated and implementing acts.
• European Commission by removing barriers why CPOs should not be able to deliver the right data and NAPs are not able to collect the required data. This makes it easier to comply to regulations and remove barriers for data sharing. 

DATEX II is not an OCPI format. Because the market already communicates in OCPI [10], the shortest route to help CPOs comply with the legislation is to map the AFIR data requirements onto OCPI 2.3.0. With support of the Dutch
Ministry of Infrastructure and Water Management (I&W), the EVRoaming Foundation has commissioned a NAP OCPI Test Tool Module so that a CPO can validate whether it meets the legislation. A 100% mapping onto OCPI is not possible. A number of AFIR data types therefore require new fields that a CPO must also send towards the NAP. The
purpose of this extension is to define and standardise those data elements at the OCPI level, enabling interoperability between market parties, allowing CPOs to demonstrate AFIR-NAP compliance, and allowing the OCPI Test Tool to validate both the standard and the new fields. This extension is designed to be applicable across multiple OCPI versions.

The EVRoaming Foundation aims to support the accessibility of charging infrastructure for all users. Everyone should be able to find a charging station that meets their needs and is easy to use, including people with disabilities who may require additional accessibility and usability support. The EVRoaming Foundation partners with the European Commission, UK Department for Transport, and several other governments and regulators to improve this. 

The OCPI Accessibility Extension aims to ensure that disabled people are able to determine whether a charging station can be used according to their individual accessibility needs. This extension is designed to be applicable across multiple OCPI versions starting from v2.3.0. 

It is only an extension of data in Location module. It does not change existing items nor has it impact on other modules.

Because accessibility requirements vary, the usability of a charging station cannot be expressed through a single indicator. It depends on a set of data elements describing physical characteristics, usability features, and environmental factors that influence access and operation. 

The purpose of this extension is to define and standardize those data elements at the OCPI level, enabling interoperability between market parties and supporting informed accessibility-related decisions by users and services.

This version is also getting better implementation support; Swagger files will be available soon. Join the community to get the latest information when available.

As OCPI 2.2.1 has some crucial improvement compared to v2.2, v2.2 will not be supported anymore.

Main improvements for OCPI v2.2.1 compared to 2.2 can be found in this file: OCPI v2.2.1 changes

Deliverable d2 has important updates in the description HOW to use the specifications. It should reduce confusion about how to use the specs.

OCPI 2.2.1 is a major step forward. Nevertheless, the community is already looking ahead, because developments in this field are progressing rapidly. Responding to these developments remains important. OCPI continues to evolve.

To support CPOs with payment terminals that are not directly connected to and part of the charge station, e.g. at charge squares and situation with POS terminal in a shop, the EVRoaming foundation developed (with great support of Chargepoint) the Direct Payment module that can work together with OCPI v.2.2.1.
