I have the error 'Transaction does not fullfill minimum eViolin requirements'. What does this mean?

This error message can occur under the transactions tab of a charging station.

This message means that the transaction may not meet one of the following eViolin restrictions:

  • The registered charging session volume is at least 0 kWh and no more than 350 kWh (this may be higher for truck charging).
  • The charging session duration must be longer than 2 minutes OR the volume must be higher than 0.2 kWh.
  • The card was scanned incorrectly or presented twice within a few seconds. This will not affect future transactions or the proper functioning of the charging station.

  • You incorrectly set the charger to Plug&Charge. It is possible to use roaming with a digital charging pass to circumvent using the RFID reader. The charger is set to always charge with this pass ID. For example for EVbox this is 'evb_autostart' and for Alfen this is 'PlugAndChargeIdentifier'. When a non existing charge card is filled in for this setting the charger will try to use roaming for a non existant charge pass. Charging will be blocked. Only use this setting if you know how to use it. Otherwise we advise to keep the Plug&Charge setting turned off.

  • Data is missing or was not processed correctly during a charging session.

Want to investigate further? Check the charging station's logs:

  • Check the Status Notifications to see if "SuspendedEVSE" or "SuspendedEV" appears first:
    • "SuspendedEV": This is likely a problem with the vehicle—contact the manufacturer or dealer.
    • "SuspendedEVSE": Then it's probably the charging station—contact your charging station supplier and share your findings.
  • Check whether the StartTransaction and StopTransaction are following each other up very close together for shorter than 2 minutes.
