Charge keys, Cars & Drivers
The building blocks of fleet management: charge keys (RFID or vehicle MAC address) that authorize charging, the cars they belong to, and the drivers allowed to use them.
Everything in the fleet module is built from these three pieces. Keys authorize charging, cars group keys to a vehicle, and drivers are the people (registered app users or pending email invitations) allowed to use the keys.
Charge keys
A charge key authorizes fleet charging in three ways:
- An RFID the driver taps on the charger.
- The MAC address of a vehicle's charging port, so the car identifies itself when plugged in.
- A virtual key used from the app: drivers assigned to a charge key can select it as their payment method in the EOSVOLT app and start fleet sessions from their phone, no physical tag needed. The session is settled through the fleet arrangement (team or member discount) instead of the driver's personal payment method.
The key value may contain only letters and numbers.
Add or edit keys under Fleet → Teams → Charging keys. Each key has:
- Charge key: the RFID/MAC value itself.
- Added car: the car the key belongs to (optional).
- Added Drivers: the drivers authorized to use it. Invited drivers who have not registered yet show as (pending).
- Charge Key Status: Active or Inactive. An inactive key cannot be used for charging.
A key can also carry a linked payment method, used when its sessions are billed in-app.
Cars
A car groups keys and drivers to a physical vehicle:
- Car alias, car plate number, and car VIN number.
- Add charge keys: attach the keys used with this car.
- Add drivers: assign existing drivers, or use Send charge keys to new drivers via email: the driver receives an email invitation with a unique code to add the charge keys in the app.
- Car Status: when a car is set inactive, all charge keys assigned to it become inactive too.
Drivers
A driver is either a registered app user or a pending invitation (an email that has not signed up yet):
- Add drivers by email under Fleet → List of drivers. Type an email and press Enter; add several in one go.
- Assign charge keys and/or a member discount. A driver must have at least one of the two.
- The driver list shows each driver's email, name, charge keys, fleet team, member discount, and total kWh and sessions.
How they connect
Keys attach to drivers directly (a driver can hold several keys, and a key can serve several drivers). Keys can also belong to a car and to a fleet team, which is where team pricing and spending limits come from: see Teams & Member Discounts.
Common questions
What can I use as a charge key? An RFID card/tag, the MAC address of the vehicle's charging port, or the key can act as a virtual payment method the driver selects in the app. The value itself is letters and numbers only.
Why does a driver show as (pending)? They were invited by email but have not registered in the app yet. Their access activates when they sign up with the invitation.
A key stopped working. Why? Check four things: the key's own status (Inactive?), its car's status (an inactive car deactivates all its keys), its team's spending limit (keys disable when the limit is hit and reactivate on reset), and, at semi-public locations, whether the team is granted access to that particular charger.
A key works on one charger at a site but not the one next to it. The team's grant for that semi-public location has been narrowed to specific chargers. Open the team's Locations step and check its Charger access panel, or look at the location's Access tab to see which chargers the group holds.
Does tapping an RFID card follow the same access rules as the app? Yes. A key and the app grant the same access at semi-public locations, so a driver who can start in the app can tap in as well. Public locations are open to everyone either way.
Can one driver have multiple keys? Yes, and one key can be shared by several drivers.
How does a new employee get charging access? Add them as a driver by email and assign a charge key (or a member discount). They receive an email invitation with a unique code to activate everything in the app, after which the key appears in the app as a selectable payment method.
Can a driver start a fleet session without an RFID tag? Yes. In the app they pick their charge key as the payment method and start the session from their phone; billing goes through the fleet setup, not their personal card.
