Below are the error codes for the EV7UK / EVT7UK EV charger, with the cause of each error and the recommended troubleshooting steps.
| Error name & code | Error description | Troubleshoot |
|---|---|---|
| High temperature (0x00000002) | Charging stopped due to high temperature detected. | 1. Disconnect the charging cable. 2. Wait until the temperature returns to normal, indicated by the LED turning green. 3. Once the LED is green, reconnect the cable to resume charging. |
| Charging error (0x00000010) | The EV is requesting a charging current that exceeds the charger’s capacity. | 1. Disconnect the charging cable. 2. Check any EV settings that may cause this issue or contact your EV manufacturer. |
| Over voltage (0x00000020) | Charging stopped due to input voltage exceeding limit. | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| Under voltage (0x00000040) | Charging stopped due to input voltage being below limit. | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| Charging error (0x00000080) | Charging has stopped due to an error detected in the internal energy meter. | 1. Disconnect charging cable. 2. Switch off main power supply and contact customer service for assistance. |
| Charging error (0x00000100) | Charging stopped due to an error: the internal relay could not be switched ON. | 1. Disconnect charging cable. 2. Switch off main power supply and contact customer service for assistance. |
| Socket lock error (0x00000200) | Charging stopped because the socket failed to lock or unlock. | 1. To release a stuck charging cable, push it towards the charger and then press the Unlock button. 2. If problem persists, turn off the main power supply, then turn it back on and attempt to unplug again. 3. If the issue continues, contact customer service for assistance. |
| Charging error (0x00000400) | Charging stopped because the internal relay could not be turned OFF. | 1. Disconnect charging cable. 2. Switch off main power supply and contact customer service for assistance. |
| Charging error (0x00001000) | Charging stopped due to abnormal CP (Control Pilot) voltage detected from the EV. | 1. Disconnect charging cable. 2. Please verify your EV settings or use another charging cable (for socket type charger) to try again or contact your EV manufacturer. |
| Cable disconnected during use (0x00002000) | Charging has been paused because the connection was unexpectedly interrupted before the session could complete—either by the vehicle (EV suspend) or by the charging station (EVSE suspend). | 1. Disconnect charging cable. 2. Reconnect the charging cable and attempt to charge again. |
| Cable disconnected during use (0x00004000) | Charging stopped due to abnormal disconnection before the charging process was completed. | 1. Disconnect charging cable. 2. Reconnect the charging cable to try charging again. |
| Charging error (0x00008000) | Charging has been halted because the rotary switch for maximum charging current has been set incorrectly. | 1. Disconnect charging cable. 2. Switch off main power supply. 3. Contact technician to verify the rotary switch setting. 4. If problem persists, contact customer service for assistance. |
| Cover opened (0x00010000) | The charger’s front cover is not properly installed. | 1. Install it properly and the charger will resume normal operation. |
| Charging error (0x00020000) | Charging has stopped because residual current was detected. | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| Cable error (0x00040000) | Charging stopped due to abnormal PP voltage detected from the charging cable. | 1. Disconnect charging cable. 2. Please verify your EV settings or use another charging cable (for socket type charger) to try again. |
| Over frequency (0x00080000) | Charging stopped due to input frequency exceeding the limit. | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| Under frequency (0x00100000) | Charging stopped due to input frequency being below limit. | 1. Disconnect the charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| PEN fault (0x00400000) | Charging stopped due to a detected PEN fault. PEN is triggered when voltage between Live and Neutral >253V or <207V. | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| PEN fault (0x00800000) | Charging stopped due to PEN fault is found. (3 phase) | 1. Disconnect charging cable. 2. Switch off main power supply and contact technician to verify the electrical installation. |
| Charging error (0x01000000) | Charging has stopped because an abnormal diode voltage was detected in the EV. | 1. Disconnect charging cable. 2. Please verify your EV settings or use another charging cable (for socket type charger) to try again or contact your EV manufacturer. |
| Under voltage (0x10000000) | The input voltage briefly fell below the permissible limit but did not interrupt the charging process. | 1. Contact a technician to check the electrical installation and improve input voltage stability. |
