Local Authorization Management

Local authorization feature provides that the charger can authorize customers/drivers without using the central system, while being offline.

The central system of Tridens EV Charge instructs the charger about the list of authorization identifiers which can be used locally by the charger to authorize the drivers for charging. Each list has a version for the operational reference. Operation can be used as full override (overrides all identifiers) or differential (add/update the specific identifiers). The system can also request a charger for the version number of the local authorization list. This way an operator/provider can find out which authorization list is currently being set up on the charger.

To manage the charging station’s local authorization list, the following operations are available from the perspective of the central system of Tridens EV Charge:

• Send local authorization list (full update).

• Send local authorization list (differential - partial update).

• Get local authorization list version.

• Handling the charging station’s configuration settings for local authorization.

Local authorization and authorization cache are separate features and cache does not impact the local authorization list.
