Reservation Status Update

Source: OCPP 2.0.1 Part 2 — Specification (Edition 2, 2022-12-15) — Section 1.46 (Messages); Use Case H04 — Reservation Ended, not used (Functional Block H. Reservation)

Overview

The Charging Station sends ReservationStatusUpdateRequest to inform the CSMS that a previously-made reservation has ended without being used (either because it expired, or because it became unusable e.g. the EVSE went Faulted/Unavailable).

This is not sent when a reservation is consumed by a transaction — in that case the CS reports the reservation termination via the reservationId field on TransactionEventRequest(Started).
