Edition 3 FINAL, 2024-05-06
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
This section contains the terminology and abbreviations that are used throughout this document.

1.2.1. Terms
Term Meaning
Charging Station The Charging Station is the physical system where an EV can be charged. A Charging Station has one or
more EVSEs.
Charging Station Charging Station Management System: manages Charging Stations and has the information for authorizing
Management Users for using its Charging Stations.
System (CSMS)
Electric Vehicle An EVSE is considered as an independently operated and managed part of the Charging Station that can
Supply Equipment deliver energy to one EV at a time.
(EVSE)
Energy Management In this document this is defined as a device that manages the local loads (consumption and production)
System (EMS) based on local and/or contractual constraints and/or contractual incentives. It has additional inputs, such as
sensors and controls from e.g. PV, battery storage.

Edition 3 FINAL, 2024-05-06
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 structu
