What are the issues to pay attention to during daily maintenance of two wheeled electric vehicle charging stations.

Nowadays, more and more people choose to buy two wheeled electric vehicles. Driven by the explosive growth of the electric vehicle market, the charging pile market has enormous potential. According to the survey, the configuration of charging stations accounts for 14.7% of the factors affecting users' purchase of electric vehicles, ranking third. The current problem with the development of electric vehicles is the insufficient range, therefore, the role of supporting facilities such as charging stations is particularly important. In the future, as the number of electric vehicles continues to rise, the demand for charging stations will also continue to increase. So how much do we know about the daily maintenance of charging stations? Today, the editor will popularize the issues that need to be paid attention to in the daily maintenance of electric vehicle charging piles.

Charging stations are generally divided into two types: conventional charging and fast charging. According to different installation methods, it can be divided into wall mounted charging piles and vertical charging piles: the fixation of wall mounted charging piles must rely on the wall, and commonly used locations are indoor or underground parking lots; Vertical charging stations can be fixed on their own and are commonly used in outdoor parking lots; According to the installation location, it can be divided into outdoor charging piles and indoor charging piles. Depending on the type of charging, it can be divided into AC charging piles and DC charging piles. AC charging piles are more suitable for small passenger electric vehicles and are widely used in public parking lots and community garages due to their low current, small size, and flexible installation. Generally, electric vehicles can be fully charged in 6-8 hours.

In the daily maintenance of charging stations, direct diagnosis method is usually used to diagnose whether there is a fault in the charging station. The methods include asking, checking, listening, and testing.

Q: By asking users, understand the common faults they encounter in their daily use.
Check: Firstly, inspect the environment of the charging parking space. Firstly, check the cleanliness of the charging parking space for any debris and inspect the surface of the charging station for any foreign objects; Next, check if the power supply and communication line connection of the charging station are normal; Check whether the fire protection facilities of the charging station comply with relevant regulations and verify the maintenance records; The second is the inspection of the charging station distribution cabinet. Check whether the door lock of the distribution cabinet is normal, whether the power indicator light is normal, whether the distribution cabinet is equipped with a protective net, whether the grounding is normal, whether the internal circuit breaker connection of the distribution cabinet is normal, and whether the current transformer connection terminal is damaged. The third is the appearance safety inspection. Check if the charging station is damaged or deformed; Whether the protective cover and waterproof device of the charging gun are normal; Whether the charging cabinet door lock is normal, and whether the circuit breaker and lightning arrester are damaged; Is the grounding of the charging station normal; Is there any odor inside; Is the connection of the charging station line normal and loose.

Listen: When the charging station is running, listen to the working sound of relays and other equipment to determine whether the charging station is properly engaged and whether the radiator is working properly.

Test: Check the function of the charging station; Inspectors use charging cards or mobile clients to check the functions of the charging station, mainly including whether the charging station is powered, whether the indicator lights, display screens, and card readers are working properly, whether the charging station equipment is connected to the internet normally, and whether the charging interface can be used normally.

Specific maintenance: 1. Number the circuit breakers and cables according to their brand, model, current, and storage location in the maintenance list, and assign a dedicated person to supervise and maintain them. 2. List and manage cable wires according to three-phase, single-phase, length, and line specifications. After pasting the length and line specifications, tie them neatly and arrange them neatly for storage. 3. Maintenance personnel should be equipped with corresponding maintenance tools, such as multimeters, clamp gauges, electric pens, insulation tape, large and small screwdrivers, wrenches, and other commonly used tools. 4. Conduct a monthly safety inspection and maintenance of the charging station. 5. During maintenance operations, a slogan similar to "When someone is working, do not close the switch" should be hung below the corresponding work area for personal safety, and protective measures should be taken.
