Verified steps Confirm the charging station reports Reservation feature support via its device model (ReservationCtrlr component/variables). Send ReserveNowRequest from the CSMS with id, expiryDateTime, idToken, and optionally an evseId to target a specific connector. Handle the ReserveNowResponse status (Accepted, Faulted, Occupied, Rejected, Unavailable) to confirm whether the reservation was placed. Send CancelReservationRequest with the reservationId to release a reservation before it's used or expires. Rely on the charging station's automatic-release mechanism to free the connector if the driver doesn't show up by expiryDateTime. Known gotchas A reservation only guarantees connector availability between now and expiryDateTime — it does not pre-authorize energy delivery or price. Not all OCPP 2.0.1 charging stations implement the Reservation functional block; check device model variables before assuming support. Canceling an already-expired or already-consumed reservation ID returns a rejected/failed status rather than a silent no-op.
