During the use of the charging pile, with the increase of running time, the technical performance of each component will gradually decline due to the influence of many factors such as heat, vibration, impact, aging and accidents. Maintenance operations include cleaning, inspection, fastening, testing, adjustment and inspection. In the maintenance and inspection of equipment, we must invite professional personnel and use professional maintenance tools to ensure the maximum working efficiency of DC charging piles. Equipment maintenance mainly focuses on prevention, and the periodic protection is divided into level 1 and level 2. The primary maintenance is to clean the dust inside and outside the equipment, tighten it, and check the indicator lights, fuses, fuses and lightning protection devices. Level II maintenance is centered on cleaning, testing, adjustment and calibration, except for the items of level I maintenance, such as cleaning and reliability inspection. Eliminating hidden dangers and adjusting parts, charging piles can be more tidy, beautiful and practical. Seasonal maintenance. Seasonal maintenance is mainly due to special protection measures for special weather and climate during the season, so that the charging pile can work normally. If you encounter a problem that is difficult to solve, you can get a faster and better solution by consulting professional technicians.

Daily maintenance can be carried out as follows:

1. Keep it clean

First of all, it is necessary to keep the parking space clean and the surface of the charging pile free of foreign bodies and dust. Secondly, it is necessary to check whether the charging pile can be charged normally, and check whether the fire-fighting facilities in the charging position are compliant.

2. Check the charging pile body.

① Check whether the charging pile indicator is normal.

② Be sure to pay attention to the fault display on the display, and repair it in time if there is any fault.

③ Be sure to pay attention to whether the charging pile is damaged or deformed, and check whether the circuit breaker and lightning protector are damaged.

④ Touch the surface of the charging pile with your hand to feel if the temperature is too high.

⑤ Press the leakage test button of the circuit breaker inside the charging pile to see if the circuit breaker can automatically disconnect, etc.

3. Check the external charging cable.

Check whether the charging pile wire interface, door lock, power supply, etc. are damaged, deformed, dropped, and there are any loose marks.

4. Electrical and control system inspection

Check whether the internal equipment of each control circuit board of the charging pile is aged or not, and see if each index is within the normal range.

5. When charging and running

When the charging pile is running, it can be judged whether the charging pile is normally engaged and whether the radiator works normally by the sound of the equipment.
