Open Charge Point Protocol 2.0
In April 2018 a new version of OCPP was released, OCPP 2.0. This new version contains a lot of new features covered in 116 use cases. OCPP 2.0 is based on JSON. See added/improved functionalities below.
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 15118:
Regarding plug-and-charge and smart charging requirements from the EV.
6) Display and messaging support:

The OCA at this moment has more than 150 active participants from 27 countries on 5 continents, but the OCPP community is even larger, with thousands of companies in 109 countries on 5 continents. Given that OCPP2.0 is a major OCPP release OCA greatly values the input of this larger OCPP community. Therefore OCPP 2.0 was not only reviewed by our experts and OCA-participants, but also by non-members who already work with OCPP. The OCA is very grateful for all the valuable feedback we have received.
