Cleared Charging Limit

Source: OCPP 2.0.1 Part 2 — Specification (Edition 2, 2022-12-15) — Section 1.9 (Messages); Use Case K13 — Reset / Release External Charging Limit (Functional Block K. SmartCharging)

Overview

The Charging Station sends ClearedChargingLimitRequest to inform the CSMS that an externally-set charging limit (e.g. from EMS, SO/DSO, or local controller) has been cleared/released, so the CS is no longer constrained by that source.

Pairs with NotifyChargingLimit (set/update) — together they cover the lifecycle of an external charging limit visible to the CSMS.
