  The indicator light might be off on your Huawei Battery Charger due to several reasons. It could be due to an abnormal upstream input power. Check the upstream input power cable. Alternatively, the upstream RCBO might be faulty, in which case you should check it and replace it if needed. The AC power cable might be damaged, loosely connected, or have other connection faults, so inspect the cable. In rare cases, the charger itself may be faulty, requiring you to contact the after-sales team.

  If the indicator on your Huawei Battery Charger is flashing red, it could indicate a few issues. It might be due to input overvoltage (AC voltage greater than 276 V) or input undervoltage (AC voltage less than 184 V). Check whether the input voltage is within the normal range. If it's a three-phase input, a phase might have failed (voltage less than 50 V). Also, charger overheat protection could be triggered, so ensure the charger is not covered, has no nearby heat sources, and the ambient temperature is within the allowed range. The charging connector might have been unplugged incorrectly, so remove and replug it. Finally, overcurrent protection could be triggered; in this case, reduce the charging current of the vehicle or consult the vehicle's after-sales service.

Why is the indicator steady red on my Huawei Battery Charger?

  A steady red indicator on your Huawei Battery Charger can mean several things. The AC input power cable of the charger might be loose, damaged, or incorrectly connected to the power distribution box; try reconnecting the cable correctly. The earthing system could be incorrectly set, requiring you to contact the installer to correct it. The charger socket might be faulty, in which case you should contact the after-sales team. The charging connector cable might be damaged or abnormal, so replace the charging connector. There might also be a risk of current leakage, so switch off the upstream RCBO and power on the charger 5 seconds later. If the fault persists after the restart, contact the after-sales service team.
