Daily maintenance of charging pile of household new energy electric vehicle

Due to the national support for low-carbon travel, more and more car owners choose to buy electric vehicles, and the electric vehicle market will become more and more popular in the future. The energy supply of electric vehicles is charging. When buying a car, the owner will install it next to the garage or parking space Charging pile , but it doesn't matter after the charging pile is installed. Routine maintenance is very important, which is not only related to power safety, but also related to the normal use of the machine. Today, follow the method of Shenglan engineer to learn the maintenance method of household electric vehicle charging pile:

1、 Understand Charging pile The situation.

Household charging piles are generally divided into conventional charging and fast charging. According to different installation methods, it can be divided into wall mounted charging pile and vertical charging pile. The fixing of wall mounted charging pile must rely on the wall, and the common place is indoor or underground parking lot; The vertical charging pile can be fixed by itself. The common place is the outdoor parking lot. According to different installation locations, it can be divided into outdoor charging pile and indoor charging pile. According to different charging types, it can be divided into AC charging pile and DC charging pile. AC charging piles are mostly suitable for small passenger electric vehicles. They are widely used in public parking lots and community garages because of their small current, small volume and flexible installation. Generally, electric vehicles can be fully charged in 6 ~ 8 hours.

II Charging pile Maintenance method of maintenance pile.

1. Environmental inspection.

First, check the cleanliness of the charging parking space, whether there are sundries and whether there are flammable and explosive objects around. Check whether there are foreign matters on the surface of the charging pile; Secondly, check whether the power supply and communication line of the charging pile are connected normally; Check whether the fire-fighting facilities at the charging location meet the relevant requirements, and check the maintenance records.

2. Check Charging pile organism.

(1) Check the color of the charge point indicator and the status of the charge point distribution box indicator.

(2) Check whether there is fault display on the display screen, and repair it in time if necessary.

(3) Check Charging pile Whether it is damaged or deformed; Whether the protective cover and waterproof device of the charging gun are normal; Whether the door lock of the charging cabinet is normal, and whether the circuit breaker and lightning arrester are damaged; Whether the charging pile grounding is normal; Whether there is peculiar smell inside; Whether the charging pile line connection is normal and loose.

(4) According to Charging pile Internal odor diagnosis is faulty.

(5) Touch whether the surface temperature of the charging pile is too high and whether there is water vapor condensation inside.

(6) Press the leakage test button of the circuit breaker inside the charging pile to see whether the circuit breaker can be disconnected automatically.

3. Check the external charging line.

see Charging pile Whether its interface, door lock, power supply, wire and other parts are damaged, deformed and fall off, and whether there are signs of looseness.

4. Check the electrical and control system.

inspect Charging pile Check whether the internal equipment of each control circuit board is aging and whether each index is within the normal value range.

5. During charging operation.

Charging pile During operation, listen to the working sound of relay and other equipment to judge whether the charging pile absorbs normally and whether the radiator works normally.

III Charging pile The maintenance of is a matter of attention.

1. Do not let heavy objects press the power line or trample on the power line. Charging is prohibited when the charging line is defective, cracked, worn, broken, exposed, etc.

2. If a machine fault is displayed, do not charge. Please contact the charge point maintenance personnel.

3. Please take waterproof and moisture-proof measures before charging in rainy days.

Above, I hope it can bring help to the owner's friends. Only by doing a good job in the maintenance of the charging pile at ordinary times can it be used safely and safely Charging pile , it can also reduce faults and prolong service life.
