Eve Control organises your charging infrastructure around a set of core entities. Understanding how they relate to each other is key to managing your setup effectively.
Core Entities
1. Organisation
The top-level container. Every user, charger, location, Charge card, and Charge card group belongs to one or multiple organisations. Organisations are fully isolated from each other — you cannot see or manage another organisation’s data unless access is explicitly granted on entity level.
2. Charging Station
A physical Alfen EV charger connected to Eve Control via OCPP. Each charger is identified in Eve Control by its OCPP Identifier — the identifier with which the charger communicates to the backoffice. This is not necessarily the serial number, as the OCPP Identifier may have been changed after purchase. Chargers can be assigned to locations and have Charge cards linked to them for charging access.
3. Location
A physical site (parking garage, office, housing complex) where one or more chargers are installed. Locations have a name, address, and other details. Charge card groups are linked to locations to grant access to all chargers at that site.
4. Charge card
Represents a charge card (RFID tag). Each Charge card has a Hidden ID (the chip UID), a Visual ID (printed on the card), and a description. Charge card can be valid or invalid, and blocked or unblocked.
5. Charge card Group
A collection of Charge card that share the same charging access. Instead of granting each Charge card individual access, you place Charge Cards in a group and link the group to locations. Charge card groups can be enabled or disabled.
How They Connect
Entities are linked through many-to-many relationships:
A charger can be assigned to one or more locations
A location can have multiple chargers and multiple Charge card groups
A Charge card group can be linked to multiple locations and contain multiple Charge cards
A Charge card can belong to multiple Charge card groups and have direct access to specific chargers
