Yes, OCPP 2.0.1 supports real-time idle fee charging for unoccupied connectors in multi-tenant CPO environments without interrupting active sessions. The protocol enables dynamic tariff updates and allows charging stations to apply fees based on connector status, even while a session is ongoing.
How It Works in Practice
OCPP 2.0.1 introduces enhanced messaging capabilities that let charging stations communicate idle status and apply fees through the Charging Management System (CMS). The system can differentiate between occupied and unoccupied connectors, ensuring that idle fees are only applied when a connector is not in use. This functionality is particularly useful for multi-tenant environments where different operators manage separate sections of a charging station.
Operators can configure idle fee rules directly within the CMS, specifying time thresholds and fee structures. These rules are then pushed to the charging station via OCPP 2.0.1, which applies them in real time. The protocol also supports remote updates, so changes to idle fee policies can be implemented instantly across a network.
What This Means for CPOs
For Charge Point Operators (CPOs), this capability improves revenue optimization by ensuring that connectors are not left idle unnecessarily. It also enhances fairness in multi-tenant setups, where operators can charge based on actual usage rather than assuming continuous availability.
OCPP 2.0.1’s support for real-time idle fee charging allows CPOs to implement dynamic pricing models that reflect demand and usage patterns. This is especially valuable in high-traffic locations such as shopping centers, office complexes, and residential buildings where connectors may remain unoccupied for extended periods.
By leveraging OCPP 2.0.1, CPOs can also maintain session integrity. Even if idle fees are applied, active charging sessions remain unaffected, ensuring no disruption to users who are currently charging their vehicles.
