What is the overvoltage and undervoltage protection during charging of Wuling Hongguang mini?

It should be a problem with the circuit. It is recommended to check the charging pile first. If there is no problem with the charging pile, contact after-sales service. The following are the reasons why the mini cannot be charged: 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 begin. The charging socket is not grounded or has poor grounding: When using a household 220V power source for charging, a ground wire is required. If there is no ground wire, charging will not work. If there is a ground wire in the socket but it has poor grounding, you can pour water on the grounding point or re-ground it. Excessive charging current or voltage: In this case, you can check the current and voltage of the charging circuit and then try charging again. High temperature of the battery control board: When the control board is at a high temperature, charging is not possible. Wait for the control board temperature to drop before charging.
