This article describes the most common error messages in the SBC web interface of ABL charging stations (models eMH2, eMH3, eMC2, eMC3) and shows you step by step how to resolve them. The error messages relate to situations where the charging station is shown as offline in the reev Platform.
Prerequisites
Access to the local SBC web interface of the ABL charging station
Access to the reev Platform
The charging station is shown as offline in the reev Platform
Troubleshooting
Transport Layer Error – TLS Connection Faulty
How do you identify the error?
The charging station is shown as offline in the reev Platform.
The system time and date in the SBC web interface do not match the actual time.
You can find the system time at the bottom of the SBC web interface.
How do you resolve the error?
The following steps are required to correct the system time: Instructions for correcting the system time
Note: An incorrect system time prevents the establishment of a valid TLS connection to the reev Platform. The connection can only be established successfully after the time has been corrected.
Transport Layer Error – Connection Failed / Unknown Error
How do you identify the error?
The charging station is shown as offline in the reev Platform.
This error frequently occurs when the SBC has been replaced.
How do you resolve the error?
Check whether the security certificates have been correctly uploaded to the SBC.
If the error persists after verification, contact ABL support: https://www.ablmobility.de/en/service/support/
Note: After an SBC replacement, the security certificates must be uploaded again, as they are not transferred automatically.
Transport Layer Error – Unresolved Address
How do you identify the error?
The charging station is shown as offline in the reev Platform.
This message frequently appears during a restart of the charging station.
How do you resolve the error?
The following steps are required to resolve the error:
Wait until the restart of the charging station is fully completed. The status will then change automatically.
If the message persists afterwards, check the backend configuration in the SBC web interface: Instructions for verifying the ABL integration
Tip: After a restart, check whether the correct backend URL is stored in the SBC web interface.
LTE Stick Issues
How do you identify the error?
The charging station is shown as offline in the reev Platform.
The LTE stick is not recognised or not correctly recognised in the SBC web interface.
How do you resolve the error?
The following steps are required to resolve the error:
Restart the charging station.
After the restart, check whether the LTE stick is correctly recognised.
If the problem persists, contact ABL support.
Offline Mode Is Activated
How do you identify the error?
The charging station is shown as offline in the reev Platform.
No error message is displayed in the SBC web interface.
Offline mode is activated in the SBC web interface configuration.
How do you resolve the error?
Activate online mode in the SBC web interface configuration.
The following steps are required to activate online mode:
Open the SBC web interface of the charging station.
Navigate to the connection settings.
Switch from offline mode to online mode.
Save the settings.
Then check in the reev Platform whether the charging station is shown as online.
Note: In offline mode, the charging station cannot establish a connection to the reev Platform. Charging sessions are not recorded in the reev Platform in this mode.
Stand-Alone Mode Is Activated
How do you identify the error?
The charging station is shown as offline in the reev Platform.
The backend URL is missing in the SBC web interface.
How do you resolve the error?
Check the backend configuration in the SBC web interface and enter the correct backend URL: Instructions for verifying the ABL integration
Note: In stand-alone mode, the charging station operates without a backend connection. For the charging station to be managed in the reev Platform, the correct backend URL must be stored.
