Information
Definition
OCPP 1.5 is an older version of the Open Charge Point Protocol used for communication between charge points and management systems. It is normally assessed alongside interoperability, supported protocol versions, firmware support and backend compatibility.
Why it matters
It may appear in legacy UK charger fleets and can affect backend compatibility, migration planning and available remote management features. For UK users, it affects day-to-day operation, supportability, data access, interoperability and the long-term usefulness of the charger.
