Overview

FprCEN/TS 16157-10 is a Technical Specification developed by CEN under the CEN/TC 278 Technical Committee for Intelligent Transport Systems (ITS). It forms Part 10 of the DATEX II data exchange specifications, focusing specifically on energy infrastructure publications. This standard helps define publication sub-models within DATEX II for exchanging information about vehicle energy infrastructure, such as electric vehicle charging stations, fuel refuelling sites, and individual refill points. Supporting both static and dynamic information, this specification ensures efficient, standardized, and interoperable data exchange between road authorities, infrastructure operators, and ITS service providers.

Key Topics

• DATEX II Energy Infrastructure Model: Defines a dedicated EnergyInfrastructure namespace within the platform-independent DATEX II model, supporting various types of vehicle energy supply infrastructure.
• Static and Dynamic Data: Separates information into static (site and station characteristics) and dynamic (availability, operational status, real-time pricing, and faults) categories for robust data exchange.
• Infrastructure Structure:
  • Energy Infrastructure Site: Describes the overall facility offering refilling services (electric, petrol, gas, etc.).
  • Energy Infrastructure Station: Parts of a site where energy refilling occurs, handling authentication, available energy products, and payment options.
  • Refill Point: Individual connection points for vehicle energy transfer, including electric charging points, petrol or diesel pumps, and gas outlets.
• Data Modelling: Specifies Unified Modeling Language (UML) structures, a data dictionary, and XML schema to ensure clarity and interoperability.
• Sustainability and Regulation: Supports compliance with relevant EU regulations on alternative fuels infrastructure and aligns with the European Commission's Sustainable and Smart Mobility Strategy.

European foreword
This document (FprCEN/TS 16157-10:2026) has been prepared by Technical Committee CEN/TC 278
“Intelligent transport systems”, the secretariat of which is held by NEN.
This document will supersede CEN/TS 16157-10:2022.
CEN/TS 16157-10:2022:
 adding elements to provide support for COMMISSION IMPLEMENTING REGULATION (EU) 2025/655
- Rules for the application of Regulation (EU) 2023/1804 of the European Parliament and of the
Council as regards specifications and procedures relating to the availability and accessibility of data
on alternative fuels infrastructure
 introducing the new namespace AfirEnergyInfrastructure (aegi) because of non-backwards
compatible model changes
 further model improvements
 correction of different bugs.
Introduction
This document defines a common set of data exchange specifications to support the vision of a seamless
interoperable exchange of road traffic and travel information across boundaries, including national,
urban, interurban, road administrations, infrastructure providers and service providers. Standardisation
in this context is a vital constituent to ensure interoperability, reduction of risk, reduction of the cost base,
promotion of open marketplaces and many social, economic and community benefits to be gained from
more informed travellers, network managers and transport operators.
Deploying intelligent transport systems in line with European Sustainable and Smart Mobility Strategy as
issued by the European Commission requires co-ordination of traffic management operation and
development of seamless pan-European information services. These jointly aim at contributing to the
transformation of the European transport system for the objectives of efficient, safe, sustainable, smart
and resilient mobility.
In this context the European Commission has been supporting the development of information exchange
between the actors of road traffic management and related services for several years. In the road sector,
DATEX II has been long in fruition, with the European Commission being fundamental to its development
through an initial contract and subsequent co-funding of the further evolution of the standard and user
support ecosystem. With this standardisation of DATEX II, there is a real basis for common exchange
between the actors of the traffic and travel information sector both in the collaboration between traffic
management organisations and their systems, as well as in coherent information provision to service
providers. DATEX II supports the requirements of the stakeholder organisations involved in the road
traffic and travel domain in compliance with the EU policy and legal frameworks aimed at the sector.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
1 Scope
This document specifies two publication sub-models within the DATEX II framework that support the
publication of information on infrastructure for vehicle energy supply. The provided data model is
separated into two publications for static and dynamic information. The static information regarding the
infrastructure is not subject to frequent changes, whereas the dynamic part offers the ability to provide
highly up-to-date information. The static part covers all relevant information on vehicle energy
infrastructure, e.g. sites, stations and refill points for electric vehicles as well as petrol, gasoline or gas-
based refuelling for vehicles. In terms of dynamic information, the availability of the infrastructure,
possible faults and a price indication are covered.
In normative Annex A, the data dictionary for the «D2Namespace» AfirEnergyInfrastructure is specified.
These publications are intended to support the exchange of informational content from road traffic
authorities issuing traffic regulation orders and organisations implementing these orders to other
organisations providing ITS services or onward information exchange.

7 «D2Namespace» EnergyInfrastructure
7.1 Overview
The namespace "EnergyInfrastructure" shall specify a data model with details of infrastructure for vehicle
energy supply. The approach is to provide all necessary details for all kinds of energy types (fuels, gases,
hydrogen and electricity). The core concept (see Figure 2) was derived from ISO/TS 21219-25 [7].
Three core elements define the model:
 «D2Class» "EnergyInfrastructureSite" represents an energy infrastructure site, i.e. a site where
vehicles can refill energy. It is described by a number of properties and parameters like for example
its included energy infrastructure stations, operation hours or its location.
 «D2Class» "EnergyInfrastructureStation" represents an energy infrastructure station that is located
on an energy infrastructure site. The station is the location on the site where the refilling can be
carried out. For fuels, it usually offers different kinds of petrol (super, regular) and diesel. For electro
mobility, it may offer different kind of connectors. Furthermore, it may offer options for the client to
pay for the product (energy) they refilled.
 «D2Class» "RefillPoint" represents a refill point that is part of an energy infrastructure station. A refill
point is defined by its ability to charge one vehicle at a time by establishing a connection between the
station and the vehicle. In most cases, a refill point is specialised to only be able to provide one kind
of energy.
These three classes shall all be a specialization of the «D2Class» "Facility" from «D2Namespace» Facilities
defined in CEN/TS 16157-12. This implies, that these classes inherit a number of facility properties, like
being versioned identifiable, operating hours, rates, URLs, information about operator and owner and
more.
EXAMPLE: Figure 1 shows the core elements of an energy infrastructure site at the example of electric charging.
Note that ElectricChargingPoint is a specialisation of RefillPoint, and connectors are only available for electric
charging points, not for other types of refill points.

7.3 The Energy infrastructure status model
7.3.1 Overview
The Energy infrastructure status model shall be located in the «D2Package» "EnergyInfrastructureStatus
Publication" and comprises a model for defining publishable information on the current status of
locations where vehicles can be refilled with energy – see Figure 10. The corresponding publication shall
exchange information on a high frequency.

Figure 10 — EnergyInfrastructureStatus class model
7.3.2 Semantics
7.3.2.1 «D2Class» EnergyInfrastructureStatusPublication
The “EnergyInfrastructureStatusPublication” class is a specific realisable case of a “PayloadPublication”
(defined in EN 16157-7). The “EnergyInfrastructureStatusPublication” class is the base class for
containing the published “EnergyInfrastructureStatus”.
7.3.2.2 «D2Class» HeaderInformation
The “HeaderInformation” class and its components is defined in EN 16157-7.
7.3.2.3 «D2Class» EnergyInfrastructureSiteStatus
The “EnergyInfrastructureSiteStatus” relates to the EnergyInfrastructureSite class (7.2.3.2.1). It is a
specialization of FacilityStatus from Namespace AfirFacilities, from which it inherits a number of status
properties, such as information about operating hours or closures. The reference to the class
EnergyInfrastructureSite is done on the level of the classes Facility and FacilityStatus by using the
versioned reference mechanism described in EN 16157-1.
The attributes in this class may be used to provide information on the available car and truck parking
spaces.
It is possible to specify the service type for the site (as well for the station), also in combination with
specific periods.
7.3.2.4 «D2Class» EnergyInfrastructureStationStatus
The “EnergyInfrastructureStationStatus” relates to the EnergyInfrastructureStation class (7.2.4.2.1). It is
a specialization of FacilityStatus from Namespace AfirFacilities, from which it inherits a number of status
properties. The reference to the class EnergyInfrastructureStation is done on the level of the classes
Facility and FacilityStatus by using the versioned reference mechanism described in EN 16157-1.
The attribute in this class may be used for each individual station to provide information whether it is
available.
7.3.2.5 «D2Class» RefillPointStatus
The “RefillPointStatus” relates to the RefillPoint class (7.2.6.2.1). It is a specialization of FacilityStatus
from Namespace AfirFacilities, from which it inherits a number of status properties. The reference to the
class RefillPoint is done on the level of the classes Facility and FacilityStatus by using the versioned
reference mechanism described in EN 16157-1.
The “RefillPointStatus” class may be used to provide information for an individual refill point regarding
its status (e.g. available, occupied or faulted), the price per delivery unit or minute (via class Rate) and an
approximated waiting time.
7.3.2.6 «D2Class» ElectricChargingPointStatus
The “ElectricChargingPointStatus” class may be used to provide additional information on the status of
an electric charging point. Due to the longer charging times compared to other refill processes, the
information whether a charging point is occupied at a certain point is much more relevant.
7.3.2.7 «D2Class» PlannedRefillPointStatus
With this class it is possible to define reservations, closures or some other status information of the refill
point in the future due to the aggregation to overallPeriod.
7.3.2.8 «D2Class» EnergyRateUpdate and EnergyPrice
With these classes, energy rates and prices can be updated. The energyRateReference is mandatory to
refer to a defined energy rate of the static model.
7.3.2.9 «D2Class» DurationValue (waitingTime)
With this class, the current waiting time at a specific refill point can be specified.
7.4 Electric charging equipment
The «D2Class» ElectricChargingEquipment (see Figure 11) shall provide an additional option to specify
an electric charging point as an equipment component in terms of a SupplementalFacility as defined in
«D2Namespace» AfirFacilies (CEN/TS 16157-12).

Figure 11 — Electric charging equipment
7.5 Associated parking
The «D2Class» AssociatedParking (see Figure 12) shall form a specialization of the «D2Class»
AssociatedFacility defined in the «D2Namespace» AfirFacilies (CEN/TS 16157-12) to support some basic
parking related information for some parking facility that is associated with this energy infrastructure
facility.
Figure 12 — Associated parking
7.6 Data types
The following data types shall be part of the energy infrastructure model:
 Watt;
 Volt;
 Ampere;
 Units – This data type allows to specify amounts in generic terms of a Unit, which can be one of the
elements in DeliveryUnitEnum.
 Bar;
 KilogramPerDay.
All of them shall be derived from the generic data type "Float" specified in EN 16157-7 – see Figure 13.

Data Dictionary for «D2Namespace» AfirEnergyInfrastructure
A.1 Overview
This data dictionary identifies the definitions and characteristics of the different classes, attributes,
association ends, data types and enumerations appearing in the data model defined in Clause 7. The data
dictionary is specified as a whole, for the whole “AfirEnergyInfrastructure” namespace.
The generic data types which are used throughout all publications are defined in EN 16157-7:2018.
The first part of the data dictionary for each publication is partitioned into subclauses which relate to
each of the UML model packages and each subclause defines the contained classes, their attributes and
any association ends defined for associations between the classes within that package.
The Data Dictionary tables use the following columns:
Column Class name: it provides the symbolic name (upper camel case) given to the corresponding class.
Where a class name is prefixed by another name separated by a dot, the first name identifies the
namespace.
Column Association end: it provides the symbolic name (lower camel case) given to the corresponding
association end.
Column Attribute name: it provides the symbolic name (lower camel case) given to the corresponding
attribute of a class.
Column Enumerated value name: It provides the symbolic name (lower camel case) given to the
corresponding enumerated value.
Column Designation: it provides the corresponding name in natural language of the corresponding class,
attribute, association end or enumeration value.
Column Definition: it provides a comprehensive definition detailing the class, attribute or association
end.
Column Stereotype: it provides a statement of the stereotype that is assigned to the class, if any – see EN
16157-1:2018, 6.2 for further details.
Column Abstract: it provides a statement as to whether the class is abstract (non-instantiable) or
concrete (instantiable).
Column Multiplicity: it provides a statement of the allowed multiplicity for the attribute or association
end.
Column Target: It provides the name of the class which is at the end of the association to which the
association end applies.
