all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical
Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations
liaising with the IEC also participate in this preparation. IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.

1. Introduction
Electric Vehicles (EVs) are becoming the new standard for mobility all over the world. This development is only possible with a
good coverage of Charging Stations. To advance the roll out of charging infrastructure, open communication standards play a key
role: to enable switching from charging network without necessarily replacing all the Charging Stations, to encourage innovation
and cost effectiveness and to allow many and diverse players participate in this new industry.
Additionally, the EV charging infrastructure is part of the Smart Grid, a larger and still evolving ecosystem of actors, devices and
protocols. In this Smart Grid ecosystem, open communications standards are key enablers for two-way power flows, real time
information exchange, demand control and eMobility services.
The Open Charge Point Protocol (OCPP) is the industry-supported de facto standard for communication between a Charging
Station and a Charging Station Management System (CSMS) and is designed to accommodate any type of charging technique.
OCPP is an open standard with no cost or licensing barriers for adoption.
1.1. OCPP version 2.0.1
This specification defines version 2.0.1 of OCPP.
After the release of OCPP 2.0, some issues were found in OCPP 2.0. Some of these issues could not be fixed issuing errata to the
specification text only, as has been done with OCPP 1.6, but required changes to the protocol’s machine-readable schema
definition files that cannot be backward compatible.
To prevent confusion in the market and possible interoperability issues in the field, OCA has decided to name this version: 2.0.1.
OCPP 2.0.1 contains fixes for all the known issues, to date, not only the fixes to the messages.
This version replaces OCPP 2.0. OCA advises implementers of OCPP to no longer implement OCPP 2.0 and only use version 2.0.1
going forward.
Any mentions of "OCPP 2.0" refers to revision 2.0.1 unless specifically stated otherwise.
1.2. Terms and abbreviations

2. New functionalities in OCPP2.0.1
OCPP 2.0.1 introduces new functionalities compared to OCPP 1.6 [OCPP1.6].
Due to improvements and new features, OCPP 2.0.1 is not backward compatible with OCPP 1.6 [OCPP1.6] or OCPP 1.5 [OCPP1.5].
2.1. Device Management
Device Management (also known as Device Model) is a long awaited feature especially welcomed by CSOs who manage a network
of (complex) charging stations (from different vendors).
It provides the following functionality:
• Inventory reporting
• Improved error and state reporting
• Improved configuration
• Customizable Monitoring
This all should help CSOs to reduce the costs of operating a Charging Station network.
Charging Station Manufacturers are free to decide themselves how much details about a Charging Station they want to publish via
Device Management: for example, they can decide what can be monitored, and what not.
2.2. Improvements for better handling of large amounts of transactions
2.2.1. One message for all transaction related functionalities
With the growing of the EV charging market, the number of Charging Stations and transactions that the CSMS needs to manage
also grows. The structure and method for reporting transaction is unified in OCPP 2.0. In OCPP 1.x, the reporting of transaction
data is split over the messages StartTransaction, StopTransaction, MeterValue and StatusNotification. With the market progressing
towards more enhanced scheduling, a need is born for more sophisticated handling of transaction data. All the StartTransaction,
StopTransaction, and transaction related MeterValue and StatusNotification messages are replaced by 'TransactionEvent'. The
StatusNotification message still exists, but only for non-transaction related status notifications about connector availability.
2.2.2. Data reduction
With the introduction of JSON over Websockets in OCPP 1.6 [OCPP1.6] a great reduction of mobile data cost can be achieved. With
OCPP 2.0, support for WebSocket Compression is introduced, which reduces the amount of data even more.
2.3. Improvements regarding cyber security
The following improvements have been added to harden OCPP against cyber attacks:
• Security profiles (3 levels) for Charging Station and/or CSMS authentication and Communication Security
• Key management for Client-Side certificates
• Secure firmware updates
• Security event log
2.4. Extended Smart Charging
In OCPP 2.0.1 Smart Charging functionality has been extended (compared to OCPP 1.6 [OCPP1.6]) to support:
• Direct Smart Charging inputs from an Energy Management System (EMS) to a Charging Station
• Improved Smart Charging with a local controller
• Support for integrated smart charging of the CSMS, Charging Station and EV ([ISO15118-1]).
5/13 Part 0 - Introduction
IEC 63584:2024 © IEC:2024
2.5. Support for ISO 15118
The ISO 15118 standard [ISO15118-1] is a newer protocol for EVSE to EV communication, compared to IEC 61851 [IEC61851-1]. ISO
15118 allows a lot of new features and more secure communication between EVSE and EV. OCPP 2.0.1 supports the ISO 15118
standard, the newly added features are:
• Plug & Charge
• Smart Charging including input from the EV
2.6. Improvements for customer experience
2.6.1. More authorization options
OCPP 1.x was designed (mainly) for Charging Stations that authorize an EV driver via an RFID card/token. If other authorization
systems or a mix of systems are used, the CSMS needs to know what system is used for which authorization. OCPP 2.0.1 has been
extended to support things like: 15118 Plug & Charge [ISO15118-1], Payment Terminals, local mechanical key, Smart-phones, etc.
2.6.2. Display Messages
This provides Charging Station Operators with the possibility to configure - from the CSMS - a message on a Charging Station to be
displayed to EV drivers. Messages can be transaction related or global.
2.6.3. EV Driver preferred languages
To be able to show messages to an EV driver in a language the driver understands best, OCPP 2.0.1 provides the possibility to send
the language preference of a driver to a Charging Station.
2.6.4. Tariff and Costs
OCPP 2.0.1 allows Charging Stations to show the applicable tariff/price before an EV driver starts charging, to show the running
total cost during a charging transaction and/or to show the final total cost after the transaction is finished.
2.7. Transport Protocols: OCPP-J Improvements
2.7.1. Simple Message routing
A description has been added on how to create a simple solution for OCPP message routing in, for example, a Local Controller. This
is defined in Part 4, Section 6: OCPP Routing.
2.7.2. No SOAP Support
OCPP 2.0.1 no longer supports SOAP as a transport protocol. This decision was taken by the OCA members, who believe that the
protocol does no longer lend itself for constrained computing resources that many Charging Stations operate under. The verbosity
of the protocol could lead to slower performance and requires a higher bandwidth, which, in many cases, leads to higher cellular
costs. SOAP is also difficult to support when communication is via local site networking.

2.8. Minor changes/extensions
2.8.1. Renamed messages
In the OCPP 1.x series, the names of all messages were kept unchanged for backward compatibility, even though some message
names were found to be confusing or misleading in practice. In OCPP 2.0.1 message names have been changed, where
appropriate, to improve clarity and understanding.
Example: RemoteStartTransaction.req: a lot of implementers though it meant the Charging Station should start the transaction, but
in fact it is a request to try to start a transaction. However, for example, if no cable is plugged in, no transaction can be started.
Since the message was always intended to be a request, it has been changed to a more logical name:
RequestStartTransactionRequest.
2.8.2. TransactionId Identification & Message Sequencing
In OCPP 2.0, transaction identifiers are generated by the Charging Station, to facilitate offline charging sessions, in contrast to
OCPP 1.x, where transaction identifiers were generated at the CSMS and sent to the Charging Station. In addition, all messages
relating to a transaction are assigned incremental sequence numbering, to facilitate transaction data completeness checking at the
CSMS.
2.8.3. Extended enumerations
Many enumerations have been extended to support more use cases, provide more options etc.
2.8.4. Offline Transaction Event Indication
Charging Stations can optionally indicate in transaction messages that a transaction event occurred while the Charging Station was
Offline. This can assist a CSMS with the processing of transactions.
2.8.5. Personal message
Message that can be shown to the EV Driver and can be used for tariff information, user greetings and for indicating why a driver is
not authorized to charge. When a driver uses an authorization method (RFID for example) and the CSMS does not authorize the
driver to start charging, this field can thus contain additional reasons to provide the driver with a meaningful explanation why (s)he
is not allowed to charge.

driver starts charging tariff information needs to be given, detailed prices
for all the components that make up the tariff plan applicable to this driver
at this Charging Station. During charging the EV Driver needs to be shown
the running total cost, updated at a regular, fitting interval. When the EV
Driver stops charging the total cost of this transaction needs to be shown.
J. Metering This Functional Block describes the functionality for sending meter values,
on a periodic sampling and/or clock-aligned timing basis.
K. Smart Charging This Functional Block describes all the functionality that enables the CSO
(or indirectly a third party) to influence the charging current/power of a
charging session, or set limits to the amount of power/current a Charging
Station can offer to an EV.
L. Firmware Management This Functional Block describes the functionality that enables a CSO to
update the firmware of a Charging Station.
M. ISO 15118 Certificate Management This Functional Block provides the installation and update of ISO 15118
certificates.
N. Diagnostics This Functional Block describes the functionality that enables a CSO to
request and track the upload of a diagnostics file from a Charging Station,
and to manage the monitoring of Charging Station data.
O. Display Message With the DisplayMessage feature OCPP enables a CSO to display a
message on a Charging Station, that is not part of the firmware of the
Charging Station. The CSO gets control over these messages: the CSO can

Zudem basiert der Standard auf OCPP 2.0.1, das als fortschrittliche und umfassende Version der Protokolle gilt. Die Anpassung an die neuesten Technologiestandards stellt sicher, dass der Standard auch zukünftige Entwicklungen in der Elektromobilität berücksichtigen kann. Da das Dokument als Fast-Track-Dokument eingereicht wurde, erkennt es die Dringlichkeit an, die im Bereich der erneuerbaren Energien und der E-Mobilität herrscht, und bietet somit eine schnelle und effiziente Lösung für aktuelle Herausforderungen. Insgesamt ist die SIST EN IEC 63584:2025 ein bedeutender Standard, der die Grundlage für eine interoperable und zukunftssichere Infrastruktur im Bereich der Elektromobilität schafft. Seine Relevanz ist unbestreitbar, da er nicht nur technische Spezifikationen liefert, sondern auch Unternehmen und Endnutzern ermöglicht, von einer nahtlosen Kommunikation zwischen Ladesäulen und Managementsystemen zu profitieren.
