How much does it cost to build a charging pile?

As environmental green has become a development trend, new energy vehicles have become a hot spot. The topics we have talked about have shifted from the experience of vehicles such as the mileage of electric vehicles to the charging piles of supporting facilities. Today, we will sort out the charging piles for everyone. Q&A for installation issues.

1. “Do you need to coordinate multiple charging stations?”

Charging piles do not think that a few holes in the ground to fix the charging pile, and then pull a wire can be, in fact, the coordination of the workload is quite large, mainly in four departments, users themselves, car companies, power companies and properties Property rights party. The application is directly applied to the company in your city and then transferred to the power supply bureau. After that, the technical engineer will look at the site and provide the construction plan. If you are installing in the community, you need to obtain the consent of the developer.

2. “Can 380 volts get an electric shock?”

Because the charging voltage of the charging pile is 380 volts, the current is 36 amps, the voltage of the residential electricity is high, and the current is strong. Therefore, the property management company and the fire department are required to coordinate, because many friends have only heard of electric vehicles, which is not true for them. Understand, and take the high route for the cable connecting the charging pile, so the safety instructions issued by the fire department are required.

3. “Do individuals still need to pay the installation fee?”

The charging pile needs the power distribution room to re-based the power distribution, because the power load of each cell is calculated before installation. If the cell uses 100 volts, it will only give you a 120 volt electrical switch. Therefore, the high voltage of the charging pile of 380 volts must be separately powered, that is, another switch is arranged, which involves a cost of more than 8,000 yuan, which is borne by ourselves. Then, the power company pulled the wires from the switch to the charging pile about 200 meters. The construction cost, including the hardware cost of the charging pile, was borne by the power company, about 60,000 yuan. Among them, the country has a corresponding subsidy policy for the power company. . At the same time, you need to pay for the property.

4. “Is it difficult to construct?”

During the construction process, we have to coordinate the installation of the power distribution cabinet, and ask the owners to move the vehicle for construction. The cable connecting the charging pile is thicker than the child's arm. The current of each charging pile is 36 amps, and the four are 144 amps. In the future, the number of charging piles will increase. Without such a thick cable, it cannot withstand more current. The cable is not laid on the ground, but from the air, because the underground parking lot enters and exits a lot of vehicles, laying on the ground, once the cable is crushed, the consequences are unimaginable. From the air frame, the workload is much larger. But for the sake of safety it is still worth it. In order to cable from the air, the four workers took four days to re-peel the previously laid wire trough and lay the cable.

5. "How much is it per kilowatt hour?"

The electricity bill is calculated according to the commercial use. Our cell is calculated according to the average power of 1.26 yuan per kilowatt. However, some cell meters can automatically calculate which time period the electricity price is cheap and automatically adjust the charging time, which will save more money.

6. “How much does it cost to build a charging pile?”

It is reported that regardless of the land cost, the construction of a battery rental station (excluding batteries) for the replacement of battery services for 50 electric buses will total 30 million to 40 million yuan; 30 electric vehicles will be built on the basis of existing parking lots. The total investment of the bus charging station is 10 million yuan; the total investment of a commercial charging station with 9 charging spaces is at least 5 million yuan; the investment of a roadside charging pile is at least 25,000 yuan.

The price of a single charging pile ranges from two thousand yuan to 10,000 yuan. There are two types of self-use charging piles, one is "wall hanging" and the other is "buried". The buried charging pile can be used only by grounding, embedding and energizing. The whole process can be controlled within one or two hours. As for the wall-mounted charging pile, the installation is faster. From the charging method, the charging pile has a DC charging pile and an AC charging pile.

For private car owners, the first condition for installing a charging pile is to have their own private parking space. Experts say that charging the pile in the underground parking space is relatively better. Power can be found near underground parking spaces. It is relatively simple to direct electricity to the parking space, and the air transportation will not hinder others. Moreover, there are relatively few pedestrians in the underground garage.

7. “Is the charging pile safe?”

Experts said that the safety performance of the charging pile can be guaranteed to the maximum extent. When installing the charging pile, it will be as close as possible to the closed state. Only the user of the charging pile can open the charging interface to effectively prevent leakage accidents.

8. “How long does it take to charge the charging pile?”

Generally speaking, if all the conditions are met, such as the property, power supply and other departments agree, the installation plan is not very complicated, and the installation can be completed in three days. The general process is to install the company to install the installation plan, get the consent of the power supply department, send someone to install. Under normal circumstances, the charging pile can be installed in one day, and the power supply department will supply power to the charging pile after passing the acceptance.

9. “What issues should I pay attention to when installing the garage?”

For experienced installers, installing charging poles in a complex environment such as a residential underground garage will first consider the following issues:

The location of the parking space is measured to ensure that other vehicles can enter and exit normally;

Clear the location of the distribution box and confirm the distance of the power line.

Determining whether the underground garage has moisture seepage;

Make sure that the light is sufficient;

Test whether the signal in the underground garage is stable.

Then, install the charging post and plan the socket distance in advance. Before installing the charging pile, it is necessary to confirm the number of charging piles. For example, the 16-way Yunyi charging intelligent charging station with good sales on the market is taken as an example. Each socket needs to be separated by 80~100cm to ensure the smooth entry and exit of the charging vehicle. When installing the socket, you can mark it in advance and set the length of the charging cable according to the distance of the socket.

Third, the power cord is connected by a professional electrician. When connecting the final power cord, it is necessary to be operated by a professional with an electrician's license. Before that, it is necessary to ensure that the charging post is properly connected to the zero-fire line and ground wire, and the device is equipped with an air switch. After confirming that the safety is correct, re-energize and test whether the charging pile is running normally.

Finally, check the signal strength. Since the underground garage cannot be compared with the ground, it is ultimately necessary to check whether the signal strength meets the standard.
