NAP uses 3.4 version of DATEX II protocol. Only available elements of the standard have been used in NAP. Detailed information about protocol is available at link to the page Datex2.eu. A discussion forum with information about the standard is available on the website.
NAP processes the following categories data:
- difficulties in accordance with the Commission Delegated Regulation (EU) NO.886/2013 of 15 May 2013
- information on alternative fuels infrastructure in accordance with Regulation 2023/1804 of the European Parliament and of the Council (EU) of 13 September 2023

DATEX 2 PROFILE
In the NAP (KPD) the communication exchange between Data Providers and Data Receivers will be implemented using the Communication Interface. The Communication Interface will handle communicates in the Datex2 format. Below you will find a file to download with sample messages:
Alternative fuels
| Fuel Type | Data Scope |
|---|---|
| Electricity | Availability |
| Connector Type | |
| Maximum Power | |
| Organic Gas | Type of Gas |
| Hydrogen | Refueling Method |
In addition to the above-mentioned scope of data for alternative fuel infrastructure, all data compliant with the requirements of Regulation (EU) 2023/1804 of the European Parliament and of the Council of 13 September 2023 are also provided, including, among others: location, contact details, price, and operational status.
