EV Charger Error Lights Explained
Error lights are designed to alert you to a condition that needs attention, not to indicate danger.
EV chargers use indicator lights to show their status. These lights help communicate whether the charger is operating normally or if something needs to be checked. In most cases, an error light does not mean the charger is unsafe or broken.
A steady green or blue light usually indicates that the charger is powered and ready, or actively charging. A flashing light often means the charger is waiting for a scheduled charging time or communicating with the car.
Red or amber lights typically indicate an issue that has paused charging. Common causes include a loose cable connection, a temporary power fluctuation, or a communication issue between the charger and the vehicle.
If you see an error light, start by unplugging the charging cable from both the charger and the car. Wait a few seconds, then reconnect securely. This often clears temporary errors.
Next, check whether the charger is scheduled to charge later, as some chargers will display warning or standby lights while waiting for a set time. If your charger uses an app, open it to see if additional information or alerts are displayed.
If the error light persists after these checks, the charger may be signalling a condition that needs further review. This does not mean the system is unsafe. The charger’s built-in protections stop charging automatically to prevent any risk.
Different charger models use different light patterns, so the app or user guide can provide specific meanings for your device. If needed, support can help interpret the indicator and advise on next steps.
