OCPP : OCPP 2.1

OCPP 2.1 is designed for smarter, more efficient, and user-friendly EV charging solutions. It is part of our mission to stay ahead and to improve constantly. We reached this milestone thanks to the input and feedback we received from OCA participants and OCPP enthusiasts from all over the world! Together, we define the future of EV charging. 

OCPP 2.1 builds on OCPP 2.0.1 by introducing additional functionality. Care has been taken to ensure that all application logic developed for OCPP 2.0.1 remains compatible with OCPP 2.1.

OCPP 2.1 includes improved and added functionalities compared to OCPP 2.0.1: 

1. Support for ISO 15118-20: Support for ISO 15118-20 with bidirectional power transfer.
