A perspective of e-mobility standards landscape



After 2040 as the number of EVs is now doubling in the world every 18 months, it is expected that:

Hundreds of millions of public and private charging stations will be deployed everywherein homes, buildings, streets, parking lots, companies, airports, shopping moles…

Billions of successful charging sessions & transactions will have to be ensured every dayMost of these charging stations will be securely connected to operator’s systems via standardised protocolsA lot of these charging stations will allow V2G, V2H, V2B…

In 2020 : an emerging new mobility environment

Around 5 millions of EVs are circulating in the worldMore or less 1 million of public charging stations are deployed todayIndustry is learning and coping with e-mobility needs in more cities every dayLarge utilities are engaged in massive investments to support the increasing demand of electricity due to E-mobilitySmart Charging and V2G are now in the agenda of all stakeholders

IEC 63110 presentation 415/01/2020

The main objective of this keynote is to explain what is IEC 63110 and how it will manage these hundred of millions of charging stations transferring more than 1800 TWh of electricity per year into and from EV batteries.

What is in stake with E-mobility in the future ?

E-mobility and communication : the new asset of the energy landscape


How to start the design of a complex protocol standard like IEC 63110 ? The IEC methodology to define a protocol ensuring :

• Cybersecurity• Interoperability• Grid integration• Scalability

is to start with a role model and use cases.


The methodology is given by the SGAM (Smart Grid Architecture Model).More information : http://smartgridstandardsmap.com/

http://smartgridstandardsmap.com/


Why a role model is so important ?A role model is a conceptual representation of the interactions between all actors considering the roles they play in a specific market.

Communication protocols allow interactions connecting those roles through interfaces.

Communication standards describe these protocols and their ways to exchange the information captured in the use cases.

The main objective of standards is to ensure interoperability between all the actors through their different roles in their market.

Business use cases and role modelCommunication standards are the description of protocols and their way to exchange information between roles in a market model.To ensure interoperability between roles, the communication standards describe “what”is exchanged (the information) and “how” (the protocol) it is transferred from one interface to another.The “what” is described in Business use cases“How” the “what” is transmitted is described in messages transported by protocols.

Modern communication standards like IEC 63110 has one specific document for Business Use Cases and another one for messages and protocol specification.



What is IEC 63110 ?How it is organised?



What is IEC 63110 and how it is organised ?IEC 63110 is a standard developed by the JWG11 of IEC Technical Committee TC69. Initiated by France, Germany and Italy, it started in November 2017.

JWG11 is a joined Working Group between • TC 69 in charge of Electrical road vehicles and electric industrial trucks • TC 57 in charge of Power systems management and associated information exchange

TC 69 expertise is on safety and protocols for electrical mobility.

TC57 expertise is on protocols for Distributed Power system and Smart Grid.

IEC 63110 title is : “Protocol for Management of Electric Vehicles charging and discharging infrastructures”



JWG 11 members

82 experts from 21 nations ( the bigger active group in TC69)



IEC 63110 ScopeThe scope of this international standard covers the management of electric vehicles charging anddischarging infrastructures.

It will address the requirements and information exchange for the establishment of an electro mobilityeco-system, therefore covering the communication flows between the different electro mobility actors aswell as data flows with the Electric Power System.


This standard will cover the following features:•Management of energy transfer (e.g. charge session), reporting, including information exchanges related to the required energy, grid usage, contractual data, metering data.• Asset Management of EV supply equipment, including controlling, monitoring, maintenance, provisioning, firmware update, and configuration (profiles) of EV supply equipment.• Authentication/authorization/payment of charging and discharging sessions, incl. roaming, pricing and metering information.• The provision of other e-mobility services like reservation


IEC 63110 Structure of the standardTitle : Protocol for Management of Electric Vehicles charging and discharging infrastructures.

IEC 63110 is described in 3 documents:

• Part 1: Basic Definitions, Use Cases and architectures

• Part 2: Technical protocol specifications and requirements • Part 3: Requirements for conformance tests

State of work • Part 1 is currently in a stage close to CDV.• Part 2 has started its work on protocol description.

• Part 3 will not start before part 2 working draft is enough advanced.

Communication architecture



Actors - Roles interactions in IEC 63110

Some Secondary Actors can initiate data exchange through the CSMS to the CSC (e.g. Grid Operator, Service Provider, EMSP, CEM).

The CSC manages all EVSEs via a dedicated communication link (out of scope of 63110) The Charging Station is controlled by the CSMS through IEC 63110 protocol.Secondary actors may influence the charging session through messages to the CSO

This architecture however is not realistic because there are usually other loads or sources in the building and some SA (e.g. DSO or CEM) may send direct orders to some devices in the building.

?

In case of other loads or sources, a Customer Energy Management system may be present in order to optimise the energy

in the building. For that, the CEM should be able to allocate power (+/- and both ways ) to the e-mobility usage.

Problem : the CEM has no information of the current status of the EVs engaged in a charging session and can’t exchange

messages with the CSC (this is the role of the CSMS).

To solve that, IEC 63110 introduces an edge element : the Local CSMS.



General IEC 63110 communication architecture

The local CSMS can exchange messages with the cloud CSMS the CEM and the CSC.

The presence of a local CSMS will be transparent to the CSC.

The local CSMS has three functions :

• Rooting seamlessly all incoming messages between CSC and CSMS

• Interfacing with the CEM and route the messages to cloud CSMS

• Taking local decisions when local information is enough or when communication with cloud CSMS is broken

Grid, Solar Panel + battery and CS can exchange energy (both way : consumption and production)

Based on messages received from CEM and on Users contracts, the CSMS decides on the best energy/power strategy to charge-discharges EVs.

Example 1: a home with a simple IEC 63110 wallbox

For cost reasons, there is no local CSMS in that case. The CSMS connects directly to the Charging Station Controller.

A CEM functionality can be embedded in the CSC in order to read EP or DSO tariff incentives coming from the meter.

Secondary actors may exchange messages with the CSO. These messages can influence the charging or the behaviour of the CS. Examples of message from SAs : call for flexibility, signal from DSO…

Example 2: a home with production + 2 IEC 63110 wallbox managed by 1 CSO and a CEM

The CEM and the local CSMS exchange their energy/power constraints. The CEM, possibly updated by SAs, sends regularly the global energy/power budget and schedule to the local CSMS. This budget is allocated by the CSMS (either local or central) to each wallbox according their respective e-mobility needs and optimum balance with local production Load balancing between the two wallbox is an example of decision the local CSMS may take on behalf of the CSMS.

Example 3: CS managed by the CSO. Charging station is supplied by one Grid Delivery Point. There are no other loads. A group of high power EVSEs in a highway Charging Station is a good example.

Th CS being considered as a DER, the DSO may have installed a secure communication interface able to receive it’s messages and to send them to the local CSMS. Messages are related to Grid code behavior (FCR or Voltage regulation), curtailment.The CSO may also receive messages from other secondary actors like flexibility operatorsLoad balancing between EVSEs may be the responsibility of the local CSMS (with a embedded EMS functionality).

IEC 63110 Requirementsand transport technology



IEC 63110 examples of general requirements• General requirements by domain (energy-mobility-monitoring)

• Unconditional charging, smart charging, bidirectional energy transfer.• Support of V2G, V2X, Grid codes, specific role of the DSO… • Standardise exchange of information between CEM and local CSMS• Support of any type of charging technology (AC, DC, ISO 15118-2, ISO 15118-20, CHAdeMO…)

• General requirements for cyber security• Based on a risk assessment analysis• TLS mandatory for all communications• Support of ISO 15118-2 and ISO 15118-20 certificates and PKI• End-to-end security between clients and servers

• General requirements for object modelling• UML• CIM• Connection with use case through Enterprise Architect tool

• General requirements for protocol• Transport protocol (e.g. system shall support IPv6 and IPV4, TLS mandatory…)• Messaging (e.g. protocol shall support a multi-hop architecture: local and cloud based)• Support of Pub/Sub – Request/Response



IEC 63110 Message and encoding technology

JWG11 has worked since a year and a half on requirements for messaging and encoding technologies.Four candidate technologies were pre-selected :

XMPP, COAP-TCP, MQTT, DDS

Finally, on October 21st 2019, after a rigorous selection process, XMPP has been chosen by JWG11 experts.



IEC 63110 uses XMPP for transport technology

• XMPP is an open communication protocol for message-oriented middleware. It enables fast, secure, scalable, near-real-time exchange of XML data between multiple entities.

• XMPP is normalized by IETF (RFC 6120 and RFC 6121). No royalties or granted permissions are required to implement these specifications. Designed to be extensible, the XMPP Standards Foundation (XSF) develops and publishes XEPs extensions through a standard process.

• XMPP is based on XML, just like ISO 15118, so there is no need for new encoders in Charging Stations.

• XMPP is used for request/response, publish-subscribe systems, signaling for VoIP, video, file transfer, games, the Internet of Things (IoT) applications such as the Smart Grid, and social networking services.

https://tools.ietf.org/html/rfc6120

https://tools.ietf.org/html/rfc6121

https://en.wikipedia.org/wiki/XMPP_Standards_Foundation


How XMPP works• XMPP uses a decentralized Client - Server and Server - Server communication

architecture.

• This architecture enables separation of roles:• Clients (CS, CSMS, CEM) can focus on energy budget, charging process, e-mobility

services and user experience.

• Servers can focus on reliability, scalability, cybersecurity and multi-server’s federation.

• XMPP is highly secure: its core specification natively features encryption (TLS), secure authentication (SASL) and end-to-end security between servers and clients.

• The decentralized architecture of XMPP, combined with its addressing schema (similar to email), allow transparent, firewall friendly and seamless integration of Charging Stations and CEM into the IEC 63110 multi-level communication architecture.

• XMPP has the proven scaling capability required for the challenging expected e-mobility booming. XMPP is used for example by gaming platforms to securely connect every day millions of players and billions of events per server/day.

XMPP integration with Smart Grid standards

With IEC 61850-8-2 multiple Virtual Power Plants belonging to different EV charging stations, local production or storage entities can securely exchange messages through the multi-federation XMPP server’s capability.

The last version of OpenADR 2.0 uses XMPP as transport protocol (IEC 62746-10-1) ensuring even more interoperability with flexibility operators.

IEC 63110 with XMPP is a proven solution to ensure the integration of e-mobility infrastructure management into present and future IEC Smart Grid standards. DER

Use Cases and Object Models



Relations between Use cases – Object model - Messages

1. Use cases describe information exchange between systems and roles.

2. The Object model contains Packages describing devices variables and functions.

3. Messages are the way to read/write devices variables of the object model as described in the use cases.

4. Once the use cases and the objects model are in place messages can be automatically derived.

Development methodology based on Enterprise Architect, IEC 62913-1 and IEC 62559



Use cases• The Business Use cases described in IEC 63110-1 document are at the source

of IEC 63110 protocol. They capture the common, repeated, deployed or envisioned usages of the e-mobility environment.• In IEC 63110-1 document the BUC are divided in 3 domains:

• Energy Transfer Services• E-mobility services• Charging Station Management

Each of these 3 domains relies on business use cases that describe situations where business actors realise some objectives. The three domains, although they may exchange information, are relatively independent.



Energy Transfer Domain

• Smart charging - discharging• Demand Response• CSMS - CEM information exchange • DSO curtailment • Dynamic Control mode• ….

E-mobility service domain

• CS - CSMS information exchange during a Service Session

• Remote authorisation by external means• Remote authorisation with locally

presented credentials• Reservation of an EVSE• Contract tariff information• ISO 15118 contract certificates• …

Management of Charging Station

• Migration of a CS to a new CSMS• CS diagnostics• Fault code provisioning• Information display on the EVSE• Manage CS configuration• Set log criteria• CS monitoring• Update CS and CSMS certificates • Information deletion triggered by EVU or

CSMS • Firmware updates • Public tariffs information

Business use cases developed in IEC 63110-1

Sessions and TransactionsService Detail Record production


More than 30 use cases have been developed so far !


General sequence diagram of the use cases by domain and life cycle.

Except for Commissioning, Initial setup and Decommissioning, all actions are occurring in parallel.

The Use cases also belong to cycles in the life of a Charging Station

1. Installation2. Operation3. Charging sessions

1. Installation contains only Commissioning use cases2. Operation contains :

• Initial Setup• Maintenance- diagnostic• Decommissioning

3. Charging session contains the smart charging event loop



Energy Transfer domainThis business domain use cases describe relations between actors able to influence the energy transfer. This domain is by far the most important as it is related to EV user experience. The use cases describe the management of the energy transfer to one or more EVSE in order to charge or discharge the batteries of all physically connected EVs. Smart Charging is a native feature of IEC 63110 that describes real-time adaptation to events coming from Primary actors (CSMS, CS) or Secondary actors (EVs, EV users, CEM, DSO, Flexibility operators, Energy Providers, EMSP.)

Smart Charging is the core activity of IEC 63110

Example of State diagram of the Charging Session event loop

This state diagram shows an example of information flow between scenarios where CS, CSMS and CEM contribute together to :• Real time schedule update based on variation on power conditions in

the building (e.g. consumption or production)• Dynamic load balancing between EVSEs• Get Incentives from the energy market.• Respond to ancillary services request from Flexibility operators

ensuring in the same time traceability and proof of service.• Inform user and CSO

The proof of service is ensured via a specific Sessions and Transactions mechanism defined in IEC 63110


In the life of a CSMS most of the time is spent on optimising the charging sessions. In order to minimise communication between CS and CSMS, IEC 63110 will extensively use the Pub/Sub mechanism provided by XMPP. With that mechanism the CS, the CEM and the CSMS can seamlessly share events or status information without necessity of heartbeat signal and pooling, reducing dramatically the need of real-time communication bandwidth.


Sequence diagramsSessions & transactions



Sessions and TransactionsIEC 63110 will cover charge and discharge of EVs. In both cases the EV User expects to get a final invoice (the SDR for Service Detail Record) reflecting all the billable items of the Session.

For that reason, IEC 63110 defines different Sessions and Transactions.

The Sessions in IEC 63110 are not refereeing to communication session but to activities between the instant when an EVU or an EV enters into IEC 63110 scope and when they leave it. Sessions and Transactions are mainly used to identify and track billable services triggered during Charging Session cycles that will be combined and reported in the SDR.

IEC 63110 defines a Service Session and 5 sub sessions

• Authorisation Session• Energy Transfer Session• Parking Session

• Reservation Session• Other Session

• IEC 63110 supports all charging technologies by delegating the EVSE local management to the Charging Station. • Support of chargers with IEC 61851 only• Support of ISO 15118 -2 and 15118-20 certificates and PKI• Transfer to SA and EVU of critical OEM information from ISO 15118-20 DisplayParameters field

(SOC, Range, Battery capacity…)• Support of CHAdeMo chargers

• IEC 63110 has close relationships with WG 9 IEC 63119 (roaming protocol). Many members are common to these two groups. Objectives is to coordinate definitions and agree upon boundary actors use cases and information exchange.

• IEC 63110 has common objectives with TC57 with regards to Distributed Energy Resources. Particularly with IEC 61850-7-420 for DER object models.

• Messages from Flexibility Operators or from DSO to CSMS, via IEC 61850, are captured and processed by IEC 63110. Security and proof of service mechanisms included in IEC 63110 are the basis of these services.



Relation with existing management solutions

There are many existing specifications for Charging Station management. Some are open, like OCPP, other are industry proprietary developments. Most of them are not able to interoperate (for example transport technology and object model are usually different)

JWG11 mission is to develop a new international open standard ensuring interoperability with all future e-mobility technologies based on experience and contributions of experts from all the world. Interoperability with existing deployed systems is then not a reasonable option.

Among the existing specifications, OCPP claims to be one of the most used. This is why JWG11 has accepted to have an official liaison with OCA. The object of this liaison is to exchange documents and comments from their respective experts.

Many JWG11 experts, either belonging to OCA or using OCCP in their company, bring their experience on protocol and e-mobility issues to solve.

From a strict hardware point of view it is expected that CS and CSMS supporting OCPP 2.x will be able to support IEC 63110 stack.



ConclusionIEC 63110 is the international IEC standard for Charging Station Management. Based on consensus within 21 nations it prefigures the future of e-mobility management interoperability in a scalable and secure way, ensuring Grid integration and the best EV user experience.

• Objects in IEC 63110 are described as Unified Modeling Language (UML) classes. An UML class represents an object or a set of objects that share a common structure and behavior

• UML Classes have relations with other classes (for example the Charging Station can have many EVSEs).

• Some classes are also Devices that can carry Variables. The Variables are used for configuration and can be monitored.

• The Variables are defined in Datatypes. IEC 63110 uses CIMDatatypes.

• The Common Information Model (CIM) is an open standard that defines how managed elements in an IT environment are represented as a common set of objects and relationships between them. CIM is used in the Smart Grid IEC 61850 series of standards defined by TC57.

• IEC 63110 object model is still in progress and is inspired from OCPP 2.0 and IEC 61850-90-8 objects models.
