Given Snowy Conditions, What Maintenance Protocols Should Be Implemented For Electric Charging Stations?

In snowy conditions, maintaining electric charging stations requires specific protocols to ensure optimal functionality. Here are some key steps:

The snow at the station is often cleared
First of all, it is necessary to remove the snow first. DC piles with ventilation and heat dissipation, whether they are integrated piles or split piles, the ventilation of the equipment needs to go from the suction hole to the exhaust fan, and it will pass through the module halfway. In heavy snowfall, snow is more likely to be adsorbed and drift into the device, which may cause the otherwise dry module to become wet or even enter water after melting, resulting in the motherboard being burned out. Therefore, the operation and maintenance personnel must clear the snow outside the pile in time. In addition, for charging spaces, it is also important to clean them up in time. If the temperature is low and the snow is not treated in time, it may cause the road surface to freeze and affect the normal operation of the charging vehicle. Timely clearing of snow can also keep the station in good shape.

Components are often checked
In addition to timely snow removal, operation and maintenance personnel should also increase the intensity and frequency of inspection of the components inside the charging pile, and replace them in time if damaged.
For the cables inside and outside the pile, it is also necessary to strengthen the inspection, when the wire has a false connection point, a wire trip, a damaged insulation layer, an insulation fulcrum falling off, and an abnormal smell when the wire is energized, the wire may be aging. At this time, if it is raining or snow, the possibility of a fault is greater.

The gun wire is often combed, and the gun head is often wiped
At low temperatures, the charging cable will become relatively stiff, so it is recommended that the operation and maintenance personnel or the operation plant often go to the station to take care of it and organize the gun cable smoothly to prevent the charging vehicle owner from being unable to untie it. In addition, the tip of the gun that may be exposed is also a key concern. If the tip of the gun has snow entering, it melts into water and then freezes, if it is not wiped in time, it is prone to insulation failure when charging. Therefore, O&M personnel should also pay attention to the status of the gun head in time to prevent water or freezing.

Remind the owner of the charging precautions
Special posters or notices can be posted in the charging station in the cold winter weather to remind charging vehicle owners of the precautions for charging in winter and improve the experience of charging users. For example, remind the owner that the air conditioner can be turned on and run for some time before charging. Because the charging demand for electric vehicles in a low-temperature state will decrease, not only will they not be fully charged, but they will also be charged slowly. In addition, you can prepare a dry cloth for the car owner or indicate in the reminder that it is recommended that the car owner wipe the charging gun head with a dry paper towel or other soft cloth to prevent the insulation failure mentioned above.
