“Authorization failed” — spelled “authorisation failed” on some networks — means the station checked the credential you presented against an account, and the check did not pass, before any energy flowed. It is an account-layer message, not a charging fault: the cable, the connector and your car were never tested. The cause sits in one of three territories — the credential, the account behind it, or the station itself — and each has a different fix.
Key Takeaways
- “Authorization failed” is an account-layer no, delivered before any energy flows — the charging hardware was never tested.
- The cause sits with the credential, the account behind it, or the station; each has a different sign and a different fix.
- Change the credential first, read the account second, move stations third — the order isolates the territory.
- It is not a card hold and not a car error message; those are different events in different layers.
What the Station Is Checking
At an access-controlled charger, starting is a permission question asked first: is this user, on this account, allowed to charge here? As what an RFID card for EV charging is explains, the card or app identifies you; the station or its platform then checks that identity against an account — its balance, status and permissions. Only a yes releases power. “Authorization failed” is the no, delivered before the session starts.
Three Territories, Three Different Fixes
| Territory | Typical causes | The sign it is this one |
|---|---|---|
| The credential | A damaged or expired card; the wrong network’s card; an app signed in to a different account than the card belongs to | A second credential — the app instead of the card, or another card — works at the same station |
| The account | A lapsed subscription; a payment method on file that has expired or been declined; a home-network account used at a partner network where roaming between the two was never enabled | The same credential fails at every station on the network, and the app shows an account or payment problem |
| The station | A faulty card reader; the station’s link to its platform is down, so it cannot check anyone | Other drivers’ credentials fail here too, while yours works at the next station |
Two distinctions keep the triage honest. It is not the pre-session card hold — a hold is what a successful check reserves against your card. And it is not your car’s “charging error” message: the car’s screen reports the car’s side, this one the account side.
Checks in Order, Standing at the Post
- Change the credential, not the station. If the card failed, try the app; if the app failed, try the card. A pass on the second convicts the first credential, not your account.
- Open the app and read the account. Check it is active, the payment method on file is current, and you are signed in to the account your card was issued to.
- Move once. Try a second station or post. Success there clears your credential and account together — report the first station with its ID, the time and the exact message.
- Use contactless where it is offered. Some stations accept a bank card directly with no account at all — NEVI-funded corridor stations in the U.S. are required to — which routes around the account layer entirely.
Access Control on EVDANCE Stations
On shared and public hardware, this check is the design, not an obstacle. The EV-AC03201T dual-connector AC station (two Type 2 connectors, up to 43 kW shared, RFID, OCPP 1.6J) reads the driver’s card and runs the authorisation against the operator’s platform, where the account lists live. The EV-ACT3204PE 22 kW wallbox (three-phase, Type 2, RFID and app) applies the same idea at shared-site scale. For operators, the lesson of the table is that many “charger faults” reported by drivers are account events — visible in the platform long before a technician is needed.
Frequently Asked Questions
Does “authorization failed” mean I was charged?
No energy was delivered, so there is no session to bill. If an amount appears reserved on your card, that is the operator’s pre-session process and your bank’s release timing; the operator’s session record for that station and time settles any dispute.
My card worked yesterday at the same station. What changed?
Usually something on the account side: a payment method expired, a subscription lapsed, or the account was changed. Hardware rarely fails overnight in a way that rejects one driver — check the account in the app before blaming the card.
Why does my card work on one network but fail on another?
Accounts live with the network that issued them. A credential works at another network’s station only where the two have a roaming arrangement covering your account.
