In the process of new energy vehicle charging pile installation, the property company, the neighborhood committee, and the fire department should be fully coordinated with each other, and the problems that need to be focused on are mainly reflected in the fact that the charging voltage ratio is higher than the residents' daily electricity voltage, and it will produce a strong electric current, which is very likely to affect the normal use of electricity by the residents of the neighborhood, resulting in the inability of residents to have a normal life. Therefore, reasonable installation of a charging pile is very necessary. These hidden dangers should be avoided in the design stage to facilitate property management and prevent fire problems.
In the preliminary stage of charging pile installation, the coordination of all aspects of the problem is completed, and we should consider the financial aspects of the problem. If the 4S store provides a free installation service, there is no need to solve the cost problem. If it is installed independently, it needs to consume a certain cost, which is mainly reflected in two aspects of the cost:
First, the distribution room for the user's electric energy to be redistributed, usually DC charging pile is 380 volts, high voltage to go independently of the power, can not be confused with the residential electricity, and at the same time to install an independent switch, the specific expenditures should be taken into account the actual situation.
Secondly, the power company from the switch to pull the wire until the charging pile needs 200 meters distance, which leads to the construction cost being relatively high, coupled with the charging pile of the hardware facilities of the investment, need to deliver a part of the cost to the power company, but also to pay the property company to pay the management costs.
After all the work in the preliminary preparation stage is in place, we enter the construction process. When installing the charging pile, it is necessary to follow the prescribed steps. The environmental conditions of various residential neighborhoods are different, the garage is located in different specific locations, and the time consumed by the installation of construction is also different, some construction conditions are convenient, with two hours to complete the task, but some construction will be affected by a variety of factors, the construction progress is relatively slow, and it takes a whole day to complete.
In order to ensure the quality of the installation, the staff should do a good job of site research before the installation and construction, communication with the residents of the community, and property company personnel to communicate with a detailed understanding of the internal situation of the community, the charging pile installation and construction of reasonable design. Owners have to do a good job communicating with the property, property, and construction personnel docking, check the quality of the cable and the labeling, clear indicators to meet the requirements before use, and pay attention to the cable on the number of records. Charging pile model selection, to listen to the new energy vehicle user's insights, from the actual starting point to determine. The staff should have a comprehensive understanding of the type of power supply belonging to the district, and the wiring can only be done after obtaining the approval of the national grid.
New energy vehicle charging pile installation construction process, staff should first determine the distance between the charging pile and the new energy vehicle, and do a good job of reservation. If the charging port of the new energy vehicle is in the side position of the charging pile, the charging pile installation construction should take this into account, the distance between the charging pile and the new energy vehicle should be more than 40 centimeters, to ensure that the use of the door will not affect the switch. If the charging pile is installed at the rear of the new energy vehicle, the distance between the charging pile and the new energy vehicle should be more than 50 centimeters.
In the process of actual installation, the charging pile and ground infrastructure should maintain a certain distance to avoid mutual influence. When the installation work is completed, it is also necessary to reserve a space for maintenance personnel to work, to ensure that the construction position meets the standard, and when it is necessary to adjust the charging pile in the later stage, the charging pile will not be damaged.
After the completion of the charging pile installation and construction, the electric car will be driven to the site for use, functional testing, to determine the use of the charging pile, the construction of the number of meters with the eyes to observe, check the numbers above the cable, compare the amount of cable used, without producing a large deviation from the gap can be delivered to the installation and construction costs.
