There are two ways a Charge Card can be authorised to start a session at a charger. You can use either or both methods.
Path 1: Direct Access
A Charge Card is added directly to the list of charge cards for that charger. This is the simplest approach and works well for a small number of chargers and charge cards.
Direct access chain: Charge Card → Charging Station
You can set this up from either direction:
From the Charging Station menu: Open the Charger, go to Charge Cards tab, and add Charge Cards
From the Charge Card menu: Open the Charge Card, go to Charging Stations tab, and add Chargers
Path 2: Location-Based Access (via Charge Card Groups)
Charge Cards are placed in a group, and the group is linked to a location that contains chargers. This is the scalable approach — ideal when managing many charge cards and chargers.
Location-based access chain: Charge Card → Charge Card Group → Location → Charging Station
A Charge Card will be allowed to charge at a station if: (1) the Charge Card is in a group, (2) the group is linked to a location, and (3) the charger is assigned to that same location.
You can manage these links from either direction:
Link Charge Card Groups to locations from the location page (Charge Card groups tab) or from the Charge Cards group page (Locations tab)
Add Charge Cards to groups from the Charge Card group page (Charge Cards tab)
Add chargers to locations from the location page (Charging stations tab) or from the charger page (Locations tab)
All Conditions for Charging
For a charge card to successfully start a charging session, all of the following must be true:
The card is registered as a Charge Card in Eve Control
The Charge Card is valid (not invalidated)
The Charge Card is not blocked
The Charge Card has access to the charger via either direct access or a Charge Card group
If using a charge Card group: the group must be enabled
