OPEN CHARGE POINT PROTOCOL 2.0.1

OCPP 2.0 was launched in April 2018 and it has been downloaded, shared and implemented by thousands of users since. Multiple parties have contributed to the OCPP 2.0 specification by sharing their experiences and implementations. Together with these developers, OCA-participants and other researchers and testers, we have updated the specification with a new release: OCPP 2.0.1.

IMPROVEMENTS FROM THE FIELD

In the past 24 months, the number of OCA-members has grown to more than 220 participants from 43 countries on 5 continents. Members and non-members have participated in five very successful OCPP 2.0 Plugfests. OCA is very lucky to have such an enthusiastic and like-minded group of supporters.

OCPP 2.0.1 incorporates improvements for things found in the first implementations of OCPP 2.0 during Plugfests and in the field. Improvements have been made in the area of security, ISO 15118, Smart Charging and the extensibility of OCPP. A better explanation of the Device Model has been added as well as several other improvements. No new functionality is added in this release.

Added/Improved functionalities compared to OCPP 1.6

1) Device Management:
Features to get and set configurations and also to monitor a Charging Station. This is a long-awaited feature, especially welcomed by Charging Station Operators who manage complex multi-vendor (DC fast) charging stations.

2) Improved Transaction handling:
Especially welcomed by Charging Station Operators who manage large numbers of charging stations and transactions.

3) Added Security:
The addition of secure firmware updates, security logging and event notification and security profiles for authentication (key management for client-side certificates) and secure communication (TLS).

4) Added Smart Charging functionalities:
For topologies with an Energy Management System (EMS), a local controller and for integrated smart charging of the EV, charging station and Charging Station Management System.

5) Support for ISO 15118:
Regarding plug-and-charge and smart charging requirements from the EV.

6) Display and messaging support:
To provide the EV driver with information on the display, for instance regarding rates and tariffs.

7) And many additional improvements requested by the EV charging community
