OCA Technology Working Group to make 'OCPP 1.6' official release02 February 2015
The Technology Working Group (TWG) is working hard to finish OCPP 2.0. Besides that, OCA received several questions about OCPP 1.5 over JSON. Based on these questions, the TWG decided to investigate the options to officially work on OCPP 1.6.
JSON is one of the big advantages of OCPP 2.0. However, OCPP 1.5, the most used version in the industry, does not officially support JSON over websockets.
To keep working with the latest standards in communication, the industry already created some ‘own’ OCPP versions of 1.5 over JSON, almost always in combination with Smart Charging functionalities. Unofficially, the term ‘OCPP 1.6’ or ‘OCPP 1.5+’ is used for these versions. However, this is not yet an official release, which may cause non-interoperable systems or misunderstandings in the industry.
The technology working group wishes to make ‘OCPP 1.6’ an official release on short notice. A small dedicated task group will be set up to solve this issue.
It is important to realize that this release is done primarily to formalize current implementations. The scope of OCPP 1.6 will therefore be limited to the next 3 items:
- JSON over websockets
- Define a common ‘Smart Charging Profile’ that matches the needs of current implementers
- Fix typo’s and other minor known issues in the OCPP 1.5 spec
This work can only be done with the help of parties that have experience with this OCPP version. A call for support has been send by the TWG to the participants. If you are willing to join the task group for OCPP 1.6, please contact us on firstname.lastname@example.org
