Daily Maintenance of Electric Vehicle Charging Station

What is EV Charging Station?

An EV charging station, also called electric vehicle charging station, electric recharging point, charging point, electronic charging station (ECS), and electric vehicle supply equipment (EVSE), is a machine that supplies electric energy for the recharging of plug-in electric vehicles—including electric cars, neighborhood electric vehicles and plug-in hybrids.

Nowadays, more and more people choose to buy electric vehicles. Driven by the explosive growth of the electric vehicle market, the EV charger market has huge potential. According to the survey, among the factors that influence users to purchase electric vehicles, the configuration of EV charger accounts for 14.7%, ranking third. The most prominent problem at the current stage of the development of electric vehicles is the lack of endurance. Therefore, the role of supporting facilities such as EV charging station is particularly important. In the future, as the number of electric vehicles continues to rise, the demand for EV charger will also continue to increase.

EV chargers are generally divided into two types: conventional charging and fast charging. According to the different installation methods, it can be divided into wall-mounted charging stations and vertical charging stations: the wall-mounted charging stations must be fixed on the wall, and the common location is indoor or underground parking lot; while the vertical charging station can be fixed by itself, and the common location It is an outdoor parking lot; according to different installation locations, it can be divided into outdoor charging stations and indoor charging stations: according to different charging types, it can be divided into AC EV charger and DC EV charger: AC charging stations are mostly suitable for small passenger electric vehicles, And because of its small current, small size, flexible installation, etc., it is widely used in public parking lots and residential garages. Generally, electric vehicles can be fully charged in 6-8 hours.

In the daily maintenance of the EV charger, the direct diagnosis method is usually used to diagnose whether the EV charger is faulty. The methods include asking, checking, listening, and testing.

Ask: By asking users to understand the common faults that users encounter in their daily use.

Check:

1.     check the environment of charging parking spaces. Firstly, 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 and communication line of the charging pile are normal; finally, check whether the fire-fighting facilities of the charging position meet the relevant requirements and check the maintenance records ;

2.     the inspection of the charging pile power distribution cabinet. Check whether the power distribution cabinet door lock is normal, whether the power indicator is normal, whether the power distribution cabinet is installed with a protective net, whether the grounding is normal, whether the internal circuit breaker wiring in the power distribution cabinet is normal, and whether the current transformer connection terminal is damaged.

3.     the 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 charging cabinet door lock is normal, whether the circuit breaker and the lightning protector are damaged; whether the charging pile is grounded normally; whether there is any peculiar smell inside; the wiring of the charging pile Whether the connection is normal and whether it is loose.

Listen: When the charging pile is running, listen to the sound of the relay and other equipment to judge whether the charging pile is normally closed and the radiator is working normally.

Test: Check the function of the charging pile; the inspector uses the charging card or mobile phone client to check the function of the charging pile, including whether the charging pile is powered, whether the indicator light, display screen, and card reader are working normally, and whether the charging pile equipment is connected to the network normally. Whether the charging port can be used normally.

Specific maintenance:

1. According to the brand, model, current and storage location, enter the number of the breaker and cable into the maintenance list, and make a special person to take care of the maintenance.

2. List the cables according to three-phase, single-phase, length, and wire gauge. After the length and wire gauge are pasted, they are bundled neatly and stored neatly.

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 safety inspection and maintenance of the charging pile once a month.

5. During maintenance operations, a slogan similar to "Someone is working, it is forbidden to close" should be hung under the corresponding work place to ensure personal safety and take protective measures.
