What Does Charging Not Possible (Mercedes-Benz) Mean on an EV Charger?
Updated March 2026
This is general guidance based on U.S. Department of Energy AFDC. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure. If anything looks or feels unsafe, stop charging and move away from the charger.
Your Mercedes-Benz is displaying a message that charging is not possible. This can appear due to a fault in the vehicle's charging system, an incompatible charger, extreme battery temperature, or a 12V battery issue.
Seeing this on the charger right now?
- Don't unplug while the charger is active. Wait for the screen to update.
- Try stopping and restarting the session from the charging app or RFID card.
- If the error persists, move to a different connector or charger if available.

What to do
- Check the MBUX or Mercedes me app for more details about the fault

- Check that the charge port flap is fully open and the port is clean
