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.
