How much do you know about the daily maintenance of electric vehicle charging piles?

Nowadays, more and more people choose to buy electric vehicles. Driven by the explosive growth of the electric vehicle market, the charging pile market has great potential. According to the survey, among the factors that affect users to purchase electric vehicles, the configuration of charging piles accounts for 14.7%, ranking third. The most prominent problem at the current stage of the development of electric vehicles is the problem of insufficient battery life. Therefore, the role of supporting facilities such as charging piles is particularly important. In the future, as the number of electric vehicles continues to rise, the demand for charging piles will also continue to increase. So how much do we know about the daily maintenance of charging piles? Today, the editor will popularize the issues that need attention in the daily maintenance of electric vehicle charging piles.


Charging piles 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 wall-mounted charging piles must be fixed on the wall, and the common places are indoor or underground parking lots; the vertical charging piles can be fixed by themselves, and the common places It is an outdoor parking lot; according to different installation locations, it can be divided into outdoor charging piles and indoor charging piles; according to different charging types, it can be divided into AC charging piles and DC charging piles: AC charging piles are mostly suitable for small passenger electric vehicles , and because of its small current, small size, and flexible installation, it is widely used in public parking lots and residential garages. Generally, electric vehicles can be fully charged in 6 to 8 hours.
In the daily maintenance of the charging pile, the direct diagnosis method is usually used to diagnose whether the charging pile is faulty. The methods include asking, checking, listening, and trying.
Question: By asking users, understand the common faults users encounter in their daily use.
Check: The first is the environmental inspection of charging parking spaces. First check the cleanliness of the charging parking space, whether there is any debris, and check whether there are foreign objects on the surface of the charging pile; secondly, check whether the power supply of the charging pile and the connection of the communication line are normal; finally, check whether the fire-fighting facilities of the charging place meet the requirements of relevant regulations, and check the maintenance records ; The second is the inspection of the charging pile distribution cabinet. Check whether the door lock of the power distribution cabinet is normal, whether the power indicator light is normal, whether the protective net is installed in the power distribution cabinet, whether the grounding is normal, whether the connection of the breaker inside the power distribution cabinet is normal, and whether the connection terminals of the current transformer are damaged. The third is appearance safety inspection. Check whether the charging pile is damaged or deformed; whether the protective cover of the charging gun and the waterproof device are normal; whether the door lock of the charging cabinet is normal; whether the circuit breaker and lightning protection device are damaged; whether the grounding of the charging pile is normal; whether there is any peculiar smell inside; Whether the connection is normal or not loose.
Listen: When the charging pile is running, listen to the working sound of the relay and other equipment to judge whether the charging pile is normally engaged and whether the radiator is working normally.
Test: Functional inspection of charging piles; inspectors use charging cards or mobile phone clients to check the functions of charging piles, mainly including whether the charging piles are powered, whether the indicator lights, display screens, and card readers are working normally, and whether the charging pile equipment is connected to the network normally. Whether the charging interface can be used normally.
Specific maintenance: 1. Number the breakers and cables according to the brand, model, current and storage location, fill in the maintenance list, and designate a special person to take care of the maintenance. 2. Manage the cables in a list according to three-phase, single-phase, length, and wire gauge. After the length and wire gauge are pasted, they are bundled and neatly arranged for storage. 3. Maintenance personnel should be equipped with corresponding maintenance tools, such as multimeters, clamp meters, electric pens, insulating tape, large and small screwdrivers, wrenches and other common tools. 4. Do a safety inspection and maintenance of the charging pile once a month. 5. During maintenance operations, slogans such as "someone is working, no switching on" should be hung under the corresponding work place to ensure personal safety and take protective measures.
