How to install charging piles and charges
How to install the charging station
1 . “The installation of charging piles requires coordination among many parties”
The charging piles do not think that a few holes are made in the ground to fix the charging piles, and then a wire can be pulled. In fact, the workload of coordination is quite large, and there are mainly four departments, the users themselves, the automobile enterprises, the electric power company and the property rights party. In terms of application, apply directly to the company in your city, and then transfer it to the power supply bureau. After that, a technical engineer will look at the site and provide a construction plan. If you are installing in a community, you also need the approval of the developer.
2, “Residents Worried380Voltage Electric Shock”
Because the charging voltage of the charging pile is 380 volts and the current is 36 amps, it is higher than the voltage and current of residential electricity, so the property management company and the fire department need to coordinate. I don’t really understand, but the cables connected to the charging piles are routed at high places, so safety instructions issued by the fire department are required.
3, “Installation fee paid1RMB”
The charging pile needs the power distribution room to re-distribute the basic power distribution, because the electricity load of each community is calculated before installation. If the voltage of 100 volts is used in the community, only a 120-volt electric switch will be provided for you. . Therefore, the high voltage of 380 volts of the charging pile must be powered separately, that is, an additional switch is arranged. This part involves a cost of more than 8,000 yuan, which is borne by ourselves. Then, the power company pulls the wire from the switch to the charging pile for about 200 meters. This construction cost, including the hardware cost of the charging pile, is borne by the power company, which is about more than 60,000 yuan. The state has a corresponding subsidy policy for the power company. . You will also need to pay property fees.
4, “Construction is difficult”
During the construction process, we need to coordinate the space for installing the power distribution cabinet, and Owners are requested to move their vehicles to facilitate construction. The cable connecting the charging piles is thicker than a child’s arm. The current of each charging pile is 36 amps, and 4 is 144 amps. In the future, the number of charging piles will be increased. Without such a thick cable, it cannot withstand higher currents. The cables are not laid on the ground, but from the air, because there are many vehicles entering and exiting the underground parking lot, and they are laid on the ground. Once the cables are crushed, the consequences will be unimaginable. If they are installed from the air, the workload is much larger. , but it’s worth it just to be on the safe side. In order to lift the cable from the sky, the four master workers spent 4 days re-stripping the previously arranged wire trough and laying the cable.
5 , “per kWh1.26yuan”
The electricity bill is calculated based on commercial electricity consumption. In our community, it is calculated based on an average of 1.26 yuan per kilowatt-hour of electricity. However, some residential electricity meters can automatically calculate which time period the electricity price is cheaper and automatically adjust the charging time, which will save money.
6. How much does it cost to build a charging pile?
It is reported that, regardless of land costs, the total investment in building a battery rental station (excluding batteries) that provides battery replacement services for 50 electric buses is 30 million to 40 million yuan; The total investment in building a charging station for 30 electric buses on the basis of parking lots is 10 million yuan; the total investment in building a commercial charging station with 9 charging parking spaces is at least 5 million yuan; the investment in one roadside charging pile The amount is at least 25,000 yuan.
From the perspective of Bao Industrial and Commercial City, the largest electric vehicle e-commerce company in the country, the price of a single charging pile ranges from more than 2,000 yuan to 10,000 yuan. There are two types of charging piles for personal use. Wall-mounted” type, one is “buried” type. Buried charging piles can be used only by laying the foundation, burying the wires, and electrifying, and the whole process can be controlled within one or two hours. As for the installation of wall-mounted charging piles, it is faster. In terms of charging methods, charging piles include DC charging piles and AC charging piles.
For private car owners, the first condition for installing charging piles is to have their own private parking spaces. Experts say that it is relatively better to install charging piles in underground parking spaces. The power supply can generally be found near the underground parking space. It is relatively simple to lead the electricity to the parking space, and the aerial wiring will not hinder others. Also, there are relatively few pedestrians in the underground garage.
7. Is the charging pile safe?
Experts said that the safety performance of charging piles can be guaranteed to the greatest extent technically. When the charging pile is installed, it will be made into a closed state as much as possible, and only the user of the charging pile can open the charging interface to effectively prevent leakage accidents.
8. How long does it take to install the charging pile?
Generally speaking, if all conditions are met, such as 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 that the installation company issues an installation plan, and after obtaining the consent of the power supply department, it sends someone to install it. 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 the acceptance is passed.
9. Maintenance of charging piles
Private car owners do not need special maintenance in using charging piles, just ask the charging pile installation company to check regularly. That’s it.
