Technical support

Electric vehicle charging pile manufacturers believe that when purchasing electric vehicle charging piles, users must first understand the connection method of current conversion within the equipment, as well as some principles and techniques. When a DC charging pile is required for charging, use the power cord and connector to connect to the electric vehicle. At this time, the DC charger power cord and connector are permanently fixed on the charger. Using this connection method can prevent users from pulling and placing wires randomly during charging, making the operation safer and more reliable. It is convenient for the management of staff in the charging station.
​
When a user needs to use an AC charging pile for charging, the power supply cable and plug should be permanently fixed on the electric vehicle. In this way, the user can charge at any time, so as to avoid forgetting to bring the charging equipment and causing accidents. It avoids the embarrassing situation of being unable to charge, and being fixed on an electric car also avoids cable wear and tear caused by users’ frequent carrying.

Do charging piles require regular maintenance?
Electric vehicles are a favorite means of transportation for modern commuters. Charging battery cars is a problem that needs to be solved, and electric charging stations in the community can solve this problem very well. Six points that need to be considered during the daily charging process at charging stations in the community. The electric vehicle charging pile manufacturer will briefly introduce these six maintenance elements to you.
1. Electric vehicle charging pile manufacturers remind residents to pay attention to protecting the charger when charging at residential electric charging stations.
2. When charging at the electric charging station in the community, pay attention to charging in time.
3. Electric vehicle charging pile manufacturers believe that the ambient temperature selected for charging at residential charging stations is 25°C.
4. When charging at a community charging station, pay attention to regular deep discharge.
5. When charging at the electric charging station in the community, pay attention to making full use of the maintenance conditions. Many battery car dealers can provide battery repair services, which should be taken full advantage of.
6. The electric vehicle charging pile manufacturer shared that the electric charging stations in the community must be charged every day.

There are three main ways to charge electric vehicles, one is to use public charging piles, the other is to install household charging piles in private parking spaces, and the third is to directly use household portable chargers

Safety issues are a top priority. During the charging process, strong current must pass through thousands of parts when conducting inside. If any small part among them cannot withstand it, it will cause safety risks. “In addition, “the problem of waterproofing is the same. If waterproofing is not done well, static electricity or even leakage may occur.
One advantage of the car charging gun is that it is very easy to carry. You can put the charging gun in the trunk of the car at any time and take it out to charge the car whenever it is convenient. Mr. Liu is a BYD Tang car owner. He parks his car in the parking lot on the first floor of the company. It is very convenient to get electricity. He often goes to the company to charge with a car charging gun.

1. Portable charging gun: Just connect it to a household 220V 16A three-pin socket to charge your electric vehicle.
2. Home charging pile: If you have a fixed personal parking space, you can choose to install a home charging pile. Generally, you must seek permission from the property owner.
3. Public charging piles: Generally built, maintained and operated by power companies such as State Grid and China Southern Power Grid.
Things to note when charging new energy vehicles:
1. When using household single-phase AC charging, the corresponding 220V power supply plug strip must be of reliable quality to avoid abnormal heating and ablation caused by poor contact.
2. When charging, the 220V connecting strip is prohibited from being placed in the car for charging. When charging, make sure the charging gun is plugged in and the black button on the charging gun needs to pop up normally.
3. When charging, the high-voltage distribution box under the sub-instrument is in working condition, and the relay will make several “clicking” sounds at this time; if there is an air-cooled on-board charging device, it is also in working condition, and the cooling fan is working. There will be a “buzzing” sound, which is normal.
4. The charging time should be different according to the mileage. The longer the mileage, the longer the charging time, and vice versa. The charging time should be controlled between 4-12 hours. Long-term charging is not allowed.
5. If the vehicle is not used for a long time, in order to extend the service life of the power battery, it is recommended to replenish it once a month.
6. When charging, use the matching charger, place it in a cool and ventilated place, avoid high temperature and humidity, and do not let water enter the charger to prevent electric shock accidents.

What should I do if the EV charging gun of the charging pile cannot be pulled out?

1. Press the “Emergency Stop” button
Since the EV charging gun interface has a locking function to avoid disconnection during charging, locking may occur. You can try to find the emergency unlocking device. Since there are many types of charging guns, the location of the unlocking port may be different. Keep a screwdriver in the car, which can come in handy at this time. Insert the screwdriver into the unlocking port. Pull it toward the gun head to unlock.
2. Start charging again
Click to start charging, end charging after 20 seconds, and the locking mechanism will most likely be unlocked. In addition, some users reported that after unlocking the car door, the charging gun will automatically unlock, but this method is not available for all models.
3. Contact customer service
Generally, the customer service contact information will be left on the charging pile. You can call for consultation, tell the charging pile code, and the customer service background will unlock it.
After trying the above methods, if the EV charging gun still cannot be pulled out, then the only possibility is that the hardware is damaged. In this case, you can only call for repair and wait for the engineering staff to handle it on site.
