This article describes how to proceed when an ABL charging station is displayed as offline in the backend or during onboarding, and which steps to follow for error analysis and connectivity checks.
Prerequisites
The following prerequisites must be met before starting the error analysis:
Access to the SBC Web Administration Interface of the charging station
Physical access to the charging station (for restart)
Internet connection on the diagnostic device (laptop or tablet)
Error Analysis: Step by Step
Follow the steps below in order to identify and resolve the cause of the offline status.
Step 1: Restart the Charging Station
A restart often resolves temporary connectivity issues. Restart the ABL charging station and then check whether the station is back online.
Step 2: Access the SBC Web Administration Interface
Connect to the SBC Web Administration Interface of the charging station to perform further diagnostics.
Step 3: Check and Update the Firmware Version
Outdated firmware can cause connectivity issues. Check whether the latest firmware version is installed and perform an update if necessary.
Note: Make sure the charging station is not disconnected from the power supply during the firmware update. An interrupted update can result in an unrecoverable error.
Step 4: Check for Error Messages in the SBC Web Interface
Check whether any active error messages are displayed in the SBC Web Administration Interface and determine the appropriate next steps accordingly.
Step 5: Check Connectivity
Check the network connection of the charging station directly via the SBC Web Administration Interface. This step is particularly relevant for stations using an LTE connection.
Tip: For LTE connections, poor mobile signal reception at the installation site may be the cause of the offline status. Check the signal strength in the SBC Web Administration Interface.
Contacting ABL Support
If the steps above do not resolve the issue, a hardware fault may be present. In this case, contact ABL Support directly.
The fastest way to reach support is via the ABL homepage, where you can create a support ticket with all relevant information: ABL Support – Create a Ticket
Note: Have the following information ready when contacting support: serial number of the charging station, error description, firmware version, and if applicable, screenshots of the error messages from the SBC Web Administration Interface.
Troubleshooting
Problem | Possible Cause | Action |
Station remains offline after restart | Network or configuration error | Perform steps 2–5 |
Error message in SBC web interface | Firmware error or configuration issue | Update firmware, review error message |
Unstable LTE connection | Poor mobile signal reception | Check signal strength, adjust antenna position if necessary |
No access to SBC web interface | Incorrect IP address or network configuration | Check network connection and IP settings |
Frequently Asked Questions
Why is my ABL charging station displayed as offline even though it is switched on?
An offline status can have various causes: an interrupted network connection, outdated firmware, or a temporary controller error. Follow the steps in this article in order to narrow down the cause.
How long does a restart of the ABL charging station take?
A restart typically takes 1–3 minutes. Wait a few minutes after the restart before checking the connection status in the backend.
What is the SBC Web Administration Interface?
The SBC (Single Board Computer) Web Administration Interface is the local configuration interface of the ABL charging station. It can be accessed via a browser within the same network and enables diagnostics, configuration, and firmware updates.
When should I contact ABL Support?
Contact ABL Support if all steps in this article have been completed and the charging station is still offline. This may indicate a hardware fault.
Can I check connectivity without access to the SBC web interface?
Without access to the SBC Web Administration Interface, diagnostic options are limited. Make sure you are connected to the same network as the charging station and verify the IP address of the station.
