Parking detection

One of the Charging Dimension properties is PARKING_TIME.

Parking is defined as 'time not charging'.

Unfortunately, there is not unified way to identify when an EV is no longer charging via OCPP messages. It is possible to use 'suspended EV', however it is too unreliable at large to be used for this purpose.

How GreenFlux identifies parking

Greenflux identifies parking when the kWh transferred between two MeterValues is less than a certain threshold. It is not 0 kWh since very late in the charging cycle sometimes minimal amounts are still charged.

This mechanism is still being improved to be more robust in edge case scenarios

Use case: Charging for parking

This is a topic on the roadmap for GreenFlux, however no date has been specified yet. (As of July 2021).

Since it is not required, Parking_time is currently not part of the CDRs but rolled up into TIME.

Use case: Unlock on Parking

It is possible via the Platform to send a remote command to stop the session and unlock the cable from the EVSE. This would allow the EVSE to be re-used by another EV driver.

This is a topic on the roadmap for GreenFlux, however no date has been specified yet. (As of July 2021).
