2. The charging station does not recognize the charging card, or transactions are not being registered.

In the logs, filter the status messages for:

• Authorize

• StartTransaction

• StatusNotifications

• StopTransaction

If any of the above status notifications are missing, it means that the charging station is not fully transmitting the transaction to the Maxem Energy Cloud.

Solution: Contact charging station vendor

Contact the manufacturer of the charging station and explain which status messages are not being generated by the charging station.

3. No error message, and the above does not apply.

When troubleshooting charging issues, it is crucial to determine whether the problem originates from the charging station or the electric vehicle (EV). Carefully check the sequence of SuspendedEVSE and SuspendedEV statuses in the log, as this order can help pinpoint the source of the issue.

Step 1: Find the Issue

1. Filter the status messages in the logs:

   • Authorize

   • StartTransaction

   • StatusNotifications

   • StopTransaction

2. Check the timestamps:

   • Focus on the notifications around the time the issue occurred.

3. Analyze the StatusNotifications:

   • Review all StatusNotifications that occurred between StartTransaction and StopTransaction at the time of the issue.

4. Check the order of specific StatusNotifications:

   • If "SuspendedEV" appears first: The issue is likely caused by the vehicle (EV).

   • If "SuspendedEVSE" appears first: The issue is likely caused by the charging station.

Step 2: Take Action

• If the issue is caused by the vehicle, contact the vehicle manufacturer or dealer for support.

• If the issue is caused by the charging station, contact the charging station manufacturer for further assistance.
