Understanding and Managing System Errors

In OCPP, all possible combinations of charging point statuses and error codes can occur. In the ChargePilot Dashboard, error codes are always displayed in the Error Notifications tile, even if the charging point’s status is not set to “Error.”

In the Charging Point Details Table (single-site view), a red info icon indicates when a charging point sends an error code.

All displayed error codes are updated in real time. Once an error is resolved—such as after a station reboot or reconnection to ChargePilot — the error information is automatically removed from the ChargePilot Dashboard.

Recommended Steps to resolve the error

1

Charging Station Offline

Charging stations may briefly go offline during restarts, like firmware updates. Additionally, stations may appear offline if the power supply to the station or internet connection is interrupted.

Charging on Offline Stations

  1. As long as power is still supplied, you can charge in offline mode. While offline, ChargePilot cannot receive data, so it assumes the charging session continues and reserves the charging power to stay within fuse limits.

  1. If fallback is enabled, the fallback setting (e.g., 6 A per phase) is deducted from the fuse limit during offline periods. Without fallback, the station’s maximum capacity (e.g., 32 A per phase) is deducted instead.

  1. You can check in the settings if fallback is supported and which value is configured.

The offline charging station is malfunctioning

  1. If you can’t charge on an offline station due to a technical issue, the fallback value will still be deducted from the fuse limit if fallback is enabled, to protect the fuse limit. ChargePilot assumes charging is possible while offline.

  1. If fallback isn’t activated, you can set the station’s capacity to 0 A in settings. Warning: setting capacity to 0 A assumes no charging occurs, so verify before doing this.

Steps to bring the charging station back online

  1. Check the power connection of the charging station.

  1. Check the power connection of the network switch.

  1. Check the cable between the charging station and the network switch.

  1. Restart the charging station via its circuit breaker.

  1. If the problem persists, please contact our support.

2

Controller Offline

In most cases, offline controllers are in a temporary state because the controller briefly lost its internet connection and/or needs to reconnect to our backend. This can happen, for example, during an update or restart. However, charging processes remain unaffected during this time. It is also possible that the power supply to the controller was interrupted, causing it to shut down.

Charging while the controller is offline

  1. Charging is possible as long as the charging stations have power.

  2. ChargePilot continues to manage charging while the internet connection is lost.

  3. While the controller is offline, no changes such as new RFID cards or prioritization of a charging point or RFID can be performed to influence the charging.

Steps to bring the controller back online:

  1. Check the internet connection of the network the controller is connected to.

  2. Verify the power connection of the controller and internet router.

  3. Restart the controller via its circuit breaker. This is different from the circuit breaker of the charging stations.

  4. If issue persists, please contact our support.

3

EMS Offline

If the connection to the Energy Management System (EMS) is lost, ChargePilot can no longer receive real-time data on available power limits. In this case, a fallback value for the EMS will automatically be applied to protect the system from overload.

What happens when the EMS connection is lost

  1. ChargePilot assumes the maximum current available based on the predefined fallback value for the EMS.

  2. The fallback value (e.g., 100 A) is deducted from the total power available for charging to ensure circuit protection.

  3. Load management will continue based on this fallback value until the connection to the EMS is restored.

Steps to restore EMS connection

  1. Verify that the EMS is powered and connected to the network.

  2. Check the modbus connection between ChargePilot and the EMS.

  3. Restart the EMS or network devices if needed.

  4. If issue persists, please contact our support.

4

EMS Unknown

When the controller is offline, ChargePilot doesn’t receive any information on the meter status anymore.

5

Meter Offline

Meter Offline: When the connection to the meter is lost, ChargePilot can no longer monitor real-time power consumption data. To ensure system safety, a fallback value for the meter will be automatically applied.

What happens when the meter connection is lost:

  1. ChargePilot assumes the meter's fallback value (e.g., 50 A) as the maximum power consumption.

  2. This fallback value is deducted from the total available power to prevent overload.

  3. Load management will continue using this fallback value until the meter connection is restored.

Steps to restore meter connection:

  1. Ensure the meter is powered and connected to the network.

  2. Check the network connections between the meter and ChargePilot (cables, switches, etc.).

  3. Restart the meter or related network devices if necessary.

  4. If issue persists, please contact our support.

6

Meter Unknown

When the controller is offline, ChargePilot doesn’t receive any information on the meter status anymore.
