Information
Definition
Diagnostics are the tools, messages, logs or checks used to identify charger faults, performance issues or communication problems. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.
Why it matters
Good diagnostics reduce downtime, improve maintenance and help operators support users across UK charging networks. For UK users, it affects day-to-day operation, supportability, data access, interoperability and the long-term usefulness of the charger.
