Protection Functions

Input and output of the EV charger station are electrically isolated.
The output includes a back-feed prevention device to stop the vehicle battery pack from charging the charger’s output filter capacitor and to prevent instantaneous high current at the charger’s output terminal when the battery pack is connected.
Specify the charger’s voltage rating and insulation class; ensure compliance with applicable “Electric Vehicle Conductive Charging Device” regulations.
Designed and manufactured according to IEC 61851-1:2017 and IEC 62196-2:2016.

Common Malfunctions	Method Of Exclusion
Air switch burnt out	Replace the air switch.
The information acquisition board is burned out	Contact the manufacturer: replace the information acquisition board.
Module damage	Contact the manufacturer:replace the module.
Report system failure	It may be caused by various reasons such as the module and the collection board. It is recommended to contact the manufacturer.
The platform can’t connect to the Internet	Check the network cable interface, whether the network cable is plugged in properly. The network communication board is faulty and replaced.
DC Undervoltage	Check whether the fuse is burned and whether the relay is closed
AC Undervoltage	Check the wiring and switch of the power distribution cabinet for any abnormality.
The power meter on the charging Station shows zero	Unplug and plug the wires on the circuit board again, the monitoring board is faulty and replace it.
Locking card phenomenon	When the charging is complete, remember to swipe the card to pay, if the card lock phenomenon occurs, please go to the last charging machine to swipe the card and pay the fee to unlock it.
Jumping the gun phenomenon	Confirm that the IC card balance is sufficient when swiping the card, otherwise, it will automatically stop charging during the charging process.

Symptoms of common faults of the indicator lights on the module panel

There are three indicator lights on the module panel, which are the power indicator (green light), the protection indicator (yellow), and the fault indicator (red), and the fault indicator is as follows:
‍

Indicator Light	Normal Status	Abnormal State	Abnormal Problem
Power Indicator (Green)	On	Off	No input voltage; module’s internal auxiliary power supply does not operate
Protection Indicator (Yellow)	Off	On	AC input overvoltage, undervoltage, or overtemperature
Protection Indicator (Yellow)	Off	On	Communication interruption or manual mode
Fault Indicator (Red)	Off	On	Output overvoltage, module address duplication, or severe current imbalance
Fault Indicator (Red)	Off	Flashing	Faulty fan
Note: When the module is in manual mode, the yellow light flashes.
