Road vehicles - Vehicle to grid communication interface - Part 1: General information and use-case definition (ISO 15118-1:2019)

This document, as a basis for the other parts of the ISO 15118 series, specifies terms and definitions,
general requirements and use cases for conductive and wireless HLC between the EVCC and the SECC.
This document is applicable to HLC involved in conductive and wireless power transfer technologies in
the context of manual or automatic connection devices.
This document is also applicable to energy transfer either from EV supply equipment to charge the EV
battery or from EV battery to EV supply equipment in order to supply energy to home, to loads or to
the grid.
This document provides a general overview and a common understanding of aspects influencing
identification, association, charge or discharge control and optimisation, payment, load levelling,
cybersecurity and privacy. It offers an interoperable EV-EV supply equipment interface to all e-mobility
actors beyond SECC.
The ISO 15118 series does not specify the vehicle internal communication between battery and other
internal equipment (beside some dedicated message elements related to the energy transfer).
NOTE 1 Electric road vehicles specifically are vehicles in categories M (used for carriage of passengers) and
N (used for carriage of goods) (compare ECE/TR ANS/WP.29/78 ev.2). This does not prevent vehicles in other
categories from adopting the ISO 15118 series as well.
NOTE 2 This document is destined to orientate the message set of ISO 15118-2 and ISO 15118-201). The
absence of any particular use case in this document does not imply that it will not be put into practice, with the
required messages.
NOTE 3 This document, ISO 15118-2 and ISO 15118-20 are designed to work independent of data transfer
medium used. However, the ISO 15118 series is made for fitting the specified data link layers in the corresponding
documents in this series.

Véhicules routiers - Interface de communication entre véhicule et réseau électrique - Partie 1: Informations générales et définition de cas d'utilisation (ISO 15118-1:2019)

Le présent document, qui sert de base aux autres parties de l'ISO 15118, spécifie les termes et définitions, les exigences générales et les cas d'utilisation relatifs à la communication de haut niveau, par câble ou sans fil, entre le dispositif de contrôle de communication d'un véhicule électrique (EVCC) et le dispositif de contrôle de communication d'équipement d'alimentation (SECC).
Le présent document s'applique à la communication de haut niveau impliquée dans les technologies de transfert de puissance par câble et sans fil, dans le contexte de dispositifs de connexion manuelle ou automatique.
Le présent document s'applique également au transfert d'énergie de l'infrastructure de recharge au VE pour recharger la batterie du VE ou de la batterie du VE à l'infrastructure de recharge pour VE afin de fournir de l'énergie à une maison, à des charges ou au réseau électrique.
Le présent document donne un aperçu général et une compréhension commune des aspects ayant une incidence sur l'identification, l'association, le contrôle et l'optimisation de la charge ou de la décharge, le paiement, le nivellement de la charge, la cybersécurité et le respect de la vie privée. Il propose une interface VE-infrastructure de recharge pour VE interopérable à tous les acteurs de la mobilité électrique au-delà du SECC.
La série ISO 15118 ne spécifie pas la communication interne au véhicule entre la batterie et d'autres équipements internes (en dehors de quelques éléments de message relatifs au transfert d'énergie).
NOTE 1    Les véhicules routiers électriques sont spécifiquement des véhicules de catégories M (utilisés pour le transport de passagers) et N (utilisés pour le transport de marchandises) (voir l'ECE/TR ANS/WP.29/78 ev.2). Cela n'empêche pas l'adoption de l'ISO 15118 par des véhicules appartenant à d'autres catégories.
NOTE 2    Le présent document est destiné à orienter l'ensemble de messages de ISO 15118‑2 et de l'ISO 15118‑20[1]. L'absence de tout cas d'utilisation particulier dans le présent document n'implique pas qu'elle ne doit pas être mise en œuvre, avec les messages requis.
NOTE 3    Le présent document, l'ISO 15118‑2 et l'ISO 15118‑20 sont conçues pour être applicables indépendamment du support de transfert de données utilisé. Néanmoins, cette série ISO 15118 est élaborée pour s'adapter aux couches liaison de données spécifiées dans les documents correspondants de la série.

Cestna vozila - Komunikacijski vmesnik med vozilom in omrežjem - 1. del: Splošne informacije in definicija primera uporabe (ISO 15118-1:2019)

Ta dokument kot podlaga za druge dele skupine standardov ISO 15118 določa izraze in definicije, splošne zahteve in primere uporabe za kabelsko in brezžično komunikacijo na visoki ravni (HLC) med komunikacijskim krmilnikom električnega vozila (EVCC) in komunikacijskim krmilnikom opreme za napajanje (SECC). Ta dokument se uporablja za komunikacijo na visoki ravni, ki je vključena v tehnologijah kabelskega in brezžičnega prenosa moči v okviru ročnih ali avtomatskih priključnih naprav.
Ta dokument se uporablja tudi za prenos energije od opreme za napajanje električnih vozil za polnjenje akumulatorja električnega vozila ali od akumulatorja električnega vozila do opreme za napajanje električnih vozil za prenos energije v dom, obremenitve ali v omrežje.
Ta dokument podaja splošen pregled in razumevanje vidikov, ki vplivajo na identifikacijo, povezavo, nadzor in optimizacijo polnjenja ali praznjenja, plačilo, uravnavanje obremenitve, kibernetsko varnost in zasebnost. Ponuja interoperabilni vmesnik opreme za napajanje EV-EV za vse akterje e-mobilnosti, ki presega komunikacijski krmilnik opreme za napajanje.
Skupina standardov ISO 15118 ne določa notranje komunikacije v vozilu med akumulatorjem in drugo notranjo opremo (razen nekaterih namenskih elementov sporočila v zvezi s prenosom energije).
OPOMBA 1: Električna cestna vozil so zlasti vozila v kategorijah M (uporabljajo se za prevoz potnikov) in N (uporabljajo se za prevoz blaga) (primerjaj ECE/TR ANS/WP.29/78 ev.2). To ne preprečuje, da bi tudi vozila v drugih kategorijah sprejela skupino standardov ISO 15118.
OPOMBA 2: Ta dokument je namenjen usmerjanju niza sporočil iz standardov ISO 15118-2 in ISO 15118-201. Odsotnost
katerega koli primera uporabe v tem dokumentu ne pomeni, da se ne bo izvajal v praksi z zahtevanimi sporočili.
OPOMBA 3: Ta dokument ter standarda ISO 15118-2 in ISO 15118-20 so zasnovani, da delujejo neodvisno od uporabljenega medija za prenos
podatkov. Vendar pa je skupina standardov ISO 15118 oblikovana za vstavljanje določenih podatkovnih povezovalnih plasti v ustrezne dokumente v tej skupini standardov.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared jointly by Technical Committee ISO/TC 22, Road vehicles, Subcommittee
SC 31, Data communication, and Technical Committee IEC/TC 69, Electric road vehicles and electric
industrial trucks. The draft was circulated for voting to the national bodies of both ISO and IEC.
This second edition cancels and replaces the first edition (ISO 15118-1:2013) which has been technically
revised. The main changes compared to the previous edition are as follows:
— new use cases and requirements for wireless communication, wireless power transfer, automatic
connection devices and bidirectional power transfer have been added; and
— as usage of private data and cyber security are becoming an important concern for users,
requirements for more traceability and data privacy have also been added.

ISO 15118-1:2019(E)

Introduction
The pending energy crisis and the necessity to reduce greenhouse gas emissions have led vehicle
manufacturers to make a very significant effort to reduce the energy consumption of their vehicles.
They are presently developing vehicles partly or completely propelled by electric energy. Those vehicles
will reduce the dependency on oil, improve global energy efficiency and reduce the total CO emissions
2
for road transportation if the electricity is produced from renewable sources. To charge the batteries of
such vehicles, specific charging infrastructure is required.
Much of the standardisation work on dimensional and electrical specifications of the charging
infrastructure and the vehicle interface is already treated in the relevant ISO or IEC groups. However,
the question of the interoperability of information transfer between the vehicle, the local installation
and the grid is also of the upmost importance.
Such communication is beneficial for the optimisation of energy resources and energy production
systems as vehicles can charge or discharge at the most economic or most energy-efficient instants.
It is also required to develop efficient and convenient payment systems in order to cover the resulting
micro-payments. The necessary communication channel can serve in the future to contribute to the
stabilisation of the electrical grid as well as to support additional information services required to
operate electric vehicles efficiently.
The requirements of this document form the basic framework for all use cases descriptions and related
documents in the ISO 15118 series. This document is the result of a large consensus among all the actors
of the electro mobility and is a guideline for implementers of the ISO 15118 series.

General information and use-case definition
1 Scope
This document, as a basis for the other parts of the ISO 15118 series, specifies terms and definitions,
general requirements and use cases for conductive and wireless HLC between the EVCC and the SECC.
This document is applicable to HLC involved in conductive and wireless power transfer technologies in
the context of manual or automatic connection devices.
This document is also applicable to energy transfer either from EV supply equipment to charge the EV
battery or from EV battery to EV supply equipment in order to supply energy to home, to loads or to
the grid.
This document provides a general overview and a common understanding of aspects influencing
identification, association, charge or discharge control and optimisation, payment, load levelling,
cybersecurity and privacy. It offers an interoperable EV-EV supply equipment interface to all e-mobility
actors beyond SECC.
The ISO 15118 series does not specify the vehicle internal communication between battery and other
internal equipment (beside some dedicated message elements related to the energy transfer).

Introduction
The pending energy crisis and the necessity to reduce greenhouse gas emissions have led vehicle
manufacturers to make a very significant effort to reduce the energy consumption of their vehicles.
They are presently developing vehicles partly or completely propelled by electric energy. Those
vehicles will reduce the dependency on oil, improve global energy efficiency and reduce the total CO
2
emissions for road transportation if the electricity is produced from renewable sources. To charge the
batteries of such vehicles, specific charging infrastructure is required.
Much of the standardisation work on dimensional and electrical specifications of the charging
infrastructure and the vehicle interface is already treated in the relevant ISO or IEC groups. However,
the question of the interoperability of information transfer between the vehicle, the local installation
and the grid is also of the upmost importance.
Such communication is beneficial for the optimisation of energy resources and energy production
systems as vehicles can charge or discharge at the most economic or most energy-efficient instants. It is
also required to develop efficient and convenient payment systems in order to cover the resulting
micro-payments. The necessary communication channel may serve in the future to contribute to the
stabilisation of the electrical grid as well as to support additional information services required to
operate electric vehicles efficiently.
The requirements of this document form the basic framework for all use cases descriptions and related
documents in the ISO 15118 series. This document is the result of a large consensus among all the
actors of the electro mobility and is a guideline for implementers of the standard.
This edition 2 of ISO 15118-1 adds new use cases and requirements for Wireless communication,
Wireless Power Transfer, Automatic Connection Devices and Bidirectional Power Transfer. As usage of
private data and cyber security are becoming an important concern for users, requirements for more
traceability and data privacy have also being added.

DRAFT INTERNATIONAL STANDARD ISO/DIS 15118-1:2017(E)
Road vehicles — Vehicle to grid communication
interface —
Part 1:
General information and use-case definition
1 Scope
This document, as a basis for the other parts of ISO 15118, specifies terms and definitions, general
requirements and use cases for conductive and wireless High Level Communication between Electric
Vehicle Communication Controller (EVCC) and the Supply Equipment Communication Controller
(SECC).
This standard is applicable to High Level Communication involved in conductive and wireless power
transfer technologies in the context of manual or automatic connection devices.
This standard is also applicable to energy transfer either from EV supply equipment to charge the EV
battery or from EV battery to EV supply equipment in order to supply energy to home, to loads or to the
grid.
This document provides a general overview and a common understanding of aspects influencing
identification, association, charge or discharge control and optimisation, payment, load levelling,
cybersecurity and privacy. It offers an interoperable EV-EV supply equipment interface to all e-mobility
actors beyond SECC.
ISO 15118 does not specify the vehicle internal communication between battery and other internal
equipment (beside some dedicated message elements related to the energy transfer).
NOTE 1 Electric road vehicles specifically are vehicles in categories M (used for carriage of passengers) and N
(used for carriage of goods) (compare ECE/TR ANS/WP.29/78 ev.2). This does not prevent vehicles in other
categories from adopting ISO 15118 as well.
NOTE 2 This document is destined to orientate the message set of ISO 15118-2. The absence of any particular
use case in this part of ISO 15118 does not imply that it shall not be put into practice, with the required messages.
NOTE 3 This document and ISO 15118-2 are designed to work independent of data transfer medium used.
However, this series of documents are made for fitting the specified data link layers in the corresponding
documents in this series.

3.12
charge
store electrical energy in the vehicle battery
NOTE 1 to entry: In edition 1 the words “charge” or “charging” was used intensively as a generic term. In this
edition, in order to be more precise and to cover with one word Forward and Reverse Power Transfer the terms
“charge” and it declinations have been replaced by “Energy transfer” when appropriate. When energy transfer is
used in a sentence this means that both directions of power flow are possible.
NOTE 2 to entry: The term “charge” (and the associated verb) has in this text a precise definition in relation to
the amount of energy stored in the EV battery which can be different than the total energy transferred to the EV.
NOTE 3 to entry: In some sentence the word “charging” is still used. For example, the words “charging site” are
still used.
3.13
charger
power converter that performs the necessary functions for charging a battery
3.14
Charging Service Operator
CSO
secondary actor responsible for the installation and operation of a charging infrastructure (including
charging sites), and the management of electricity sourcing to provide the requested energy transfer
services
Note 1 to entry: The term CPO for Charge Point Operator is also used in ISO 15118 documents. We don’t
recommend this term for trademark reasons.
3.15
communication session
sequence of time where EVCC and SECC interactively exchange digital information in order to manage
charging or discharging the EV battery
Note 1 to entry: A communication session can be paused and resumed later several times. The communication
session encapsulates zero or more energy transfer periods.
3.16
contactor
electrically controlled switch used for switching a power circuit
Note 1 to entry: Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current.
Note 2 to entry: As far as communication is concerned the contactor occurs as a trigger for the power supply.
3.17
contract ID
contract Identification of the contract that is used by the SECC or secondary actor to enable energy
transfer and related services (including billing)
Note 1 to entry: The contract ID is associated with the electricity consumer and may be vehicle-specific or
customer-specific. The customer can e.g. be the driver, the owner of the vehicle.

3.18 Control modes
3.18.1
scheduled mode:
a control mode where the EVCC and SECC have negotiated a power profile fulfilling user's mobility
needs and based on energy target, power and tariff information.
3.18.2
dynamic mode:
a control mode, without negotiation, where a secondary actor system controls the power flow fulfilling
user's mobility needs and its own constraints.
3.18.3
flexible mode:
a control mode with a simplified negotiation where the SECC sends to the EVCC a unique power profile
compliant with user's mobility needs.
3.19
credential
document attesting the permission of the EV to be charged or to discharge
3.20
demand and prognosis
function that covers the collection of grid and local installation conditions which applies to the actual
energy transfer process
EXAMPLE Sales tariff table containing a price, CO2 content and percentage of renewable energy information
vs. time based on grid, energy production, energy demand and customer contract information, along with an
optional contract-based current limitation. Grid schedule containing a current vs. time limitation at the specific EV
supply equipment due to local installation and local electricity demand situation.
3.21
Demand Clearing House
DCH
entity for grid negotiation that provides information on the load of the grid
Note 1 to entry: The demand clearing house mediates between two clearing partners: a SECC and the part of the
power grid connected to this SECC. Most likely this function will be served by a system operator.
Note 2 to entry: Demand clearing house and meter operator may exchange information with each other as well
as with other actors.
EXAMPLE A DCH typically fulfils following tasks:
— Collect all necessary information from all parts of the power grid, e.g. current or forecasted load of local
transformers, distribution grid, power substation, transmission grid, transmission substation, power plants
(including renewable energies), and predicted energy transfer schedules submitted by EVCCs.
— Consolidate the collected grid information to a “grid profile” and offer it to SECCs/EVCCs.
— Provide energy transfer schedule proposal for the connected EV to the requesting SECC based on the
collected grid profile.
— Inform the SECC as to the necessity for an updated energy transfer schedule if the grid profile has changed.

grid)
Note 1 to entry: Electricity distribution is the final stage in the physical delivery of electricity to the delivery
point (e.g. end user, EV supply equipment or parking operator).
Note 2 to entry: A distribution system network carries electricity from the transmission grid and delivers it to
consumers. Typically, the network would include medium-voltage power lines, electrical substations and low-
voltage distribution wiring networks with associated equipment. Depending on national distribution regulations,
the DSO may also be responsible for metering the energy (MO).
