How to deal with the charging problem of Wuling Hongguang miniev?
2 Answers
The following is the relevant content about the charging problem of Wuling Hongguang miniev: 1. Loose or poor contact of the plug: You can try unplugging and replugging the plug. This situation is generally rare, because the plug needs to be tightly inserted before charging can start; 2. The charging socket is not grounded or has poor grounding: Of course, when using a household 220V power supply for charging, a ground wire is absolutely necessary. If there is no ground wire, charging will not be possible. If there is a ground wire in the socket but it has poor grounding, you can pour water at the grounding point or re-ground it; 3. Excessive charging current or voltage: In this case, you can check the current and voltage of the charging line and then try charging again; 4. High temperature of the battery control board: When the control board is at a high temperature, charging is also impossible. Wait for the temperature of the control board to drop before charging.
As a seasoned electric vehicle technician with years of experience, let me share some insights on troubleshooting Wuling Hongguang MINIEV charging issues. The most common charging failures stem from loose charging gun connections or dust accumulation in the ports – start by cleaning the ports with a cloth. Battery temperature abnormalities (overheating or extreme cold) can also cause issues; avoid charging under direct sunlight in summer, and pre-warm the vehicle before charging in winter. If the charger indicator light doesn't illuminate, check your household socket voltage stability and try alternative sockets or charging stations. Blown fuses are another frequent culprit – inspect relevant fuses in the vehicle's fuse box for melting. For persistent issues, never attempt DIY repairs on high-voltage circuits; prioritize safety and visit authorized service centers where professionals can scan fault codes and diagnose software problems like BMS abnormalities using specialized tools. For routine maintenance, conduct quarterly battery health checks, avoid deep discharges to 0%, and adopt shallow charge-discharge habits to prolong battery lifespan.
