EV Charger Error
What Does Vehicle Communication Error Mean on an EV Charger?
Updated March 2026
This is general guidance based on Open Charge Alliance (OCPP). 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.
The charger cannot communicate with your vehicle. The digital handshake between the charger and your car failed. This can happen with both AC and DC charging.
