Today, I will tell you about the construction process of new energy vehicle charging stations. The construction of the charging station is divided into five stages, namely the preparation stage, the filing stage, the construction stage, the acceptance stage, and the commissioning stage.

The preparation stage is the preparatory work in the early stage of the construction of the charging station, including market research, site determination, capital budget, site planning, site layout, and determination of pile enterprises, etc.

The filing stage includes: NDRC department project filing, legal review of land resources and land, land use review by the Planning Bureau, and application for approval by the local power bureau

The construction stage is mainly for the construction and installation of charging piles, box transformers, cables, etc.

The acceptance stage includes organizing the completion acceptance and preparing the acceptance materials

The debugging stage is mainly to debug the charging station equipment and connect it to the operation platform

The preparatory stage of the charging station construction process - surveying the market

How to assess the local market for charging facilities? We mainly analyze it from three aspects.

First, the local number of new energy vehicles, because the number of new energy vehicles determines the size of the local charging market.

Second, the number of local charging facilities can be obtained through the data on the number of local new energy vehicles and charging facilities, and the local vehicle-to-pile ratio can be obtained. The higher the vehicle-to-pile ratio, the greater the market demand for local charging facilities.

Third, the local charging facility policy mainly depends on the local charging facility planning and subsidy policy. The planning policy can understand the local promotion of the construction of charging facilities, which determines the difficulty of the approval, filing, and acceptance procedures of charging stations. Subsidy policy, you can learn about the local subsidy for the construction of charging facilities. The higher the subsidy amount, the easier it is for the charging station to make a profit.

Preparatory stage of charging station construction process - site selection

The location of the charging station should be considered in combination with the government's development plan, and should be closely combined with the current situation of the distribution network and the short-term and long-term planning to meet the requirements of the charging station for power supply and the power grid's requirements for the power quality control of the charging station. The following should be considered when selecting a location for a charging station:

First, the construction of the charging station should facilitate the acquisition of the power supply, choose to be close to the power supply end, and facilitate the entry and exit lines of the power supply.

Second, the construction of the public charging station should be selected in a place with convenient access to vehicles. It should be selected beside the urban secondary road, not near the branch road or intersection. The entrance and exit of the charging station should be connected to the urban secondary road.

Third, the newly built charging station should make full use of the nearby roads, traffic, water supply and drainage, fire protection and other municipal public facilities.

Fourth, charging stations should not be located in low-lying, water-prone places and places prone to secondary disasters.

Fifth, the charging station is not allowed to be located in places with severe vibration or high temperature, and should not be located in places with dust, water mist or corrosive gases.

Sixth, the charging station is not allowed to be set directly above or below the site with explosion hazard. When it is adjacent to a building with explosion hazard, it should meet the requirements of the regulations.

Seventh, the charging station is not allowed to be located directly below the bathroom or other places that often accumulate water, and the functional room where electrical equipment is installed should not be adjacent to the above-mentioned places.

Eighth, the charging station should meet the requirements of environmental protection and fire safety, and the fire separation distance between it and other buildings and structures should meet the relevant requirements.

Ninth, the charging station should reserve a certain spare space.

Preparatory phase of the charging station construction process - site planning

How to carry out site planning when the site is clearly defined? We mainly analyze from four aspects;

First, clarify the site facilities, which mainly include charging piles, box-type transformers, parking spaces, fire-fighting equipment, canopies, and drainage systems. Of course, you can also add supporting facilities such as lounges, self-service car washes, and self-service vending machines.

Second, to determine the entrance and exit, it is necessary to determine a reasonable entrance and exit according to the site location, main road, direction and convenience to facilitate users to charge.

Third, the utilization rate of the site. For the identified site, it is necessary to plan reasonably, use the maximum area, improve the utilization rate of the site, and ensure profitability.

Fourth, for the secondary construction, if the site is large enough, it is necessary to consider reserving the site to facilitate the secondary construction.

Preparatory phase of the charging station construction process - electrical arrangement

In the preparation stage of the charging station construction process, how to do the electrical layout of the charging station? We mainly analyze it from five aspects.

First, the layout of the electrical equipment of the charging station should follow the principles of safety, reliability and applicability, and facilitate installation, operation, handling, maintenance and debugging.

Second, high and low voltage switch cabinets, transformers, charging piles, monitoring devices, etc., should be installed in their respective functional rooms, and should be installed on the first floor of the building for easy transportation and installation.

Third, between the high and low voltage switch cabinet and the charging pile, and between the charging pile and the parking space in the charging area should be as close as possible.

Fourth, when limited by the construction site, the power transformation and distribution facilities and charging piles can be set in the outdoor combined substation, and the foundation should be properly raised to facilitate ventilation and waterproofing.

Fifth, the transformer room should not be arranged adjacent to or directly below the control center, and measures to prevent electromagnetic interference should be taken if it cannot be satisfied.

Preparatory stage of charging station construction process - station layout

In the preparatory stage of the charging station construction process, how to do the station layout of the charging station. The overall layout of the charging station shall be convenient for the access and parking of electric vehicles, and ensure the safety of personnel and facilities in the station.

First, the entrance and exit of the charging area should have at least two lanes connected to the road outside the station. The charging station should be provided with a buffer distance or buffer zone, and a parking lane for electric vehicles waiting for charging should be attached to facilitate the entry and exit of electric vehicles.

Second, the width of a single lane in the charging area should not be less than 3.5m, and the width of a double lane should not be less than 6m. The turning radius is determined according to the type of electric vehicle, and should not be less than 9m; the road slope should not be greater than 6%, and the slope should be outside the station.

Third, the charging pile should be set close to the charging area, and the electric vehicle should not hinder the charging of other vehicles in the station when charging in the parking space.

Fourth, the charging area should consider installing rain, snow, sunshade and other facilities to protect the charging facilities in the station and bring convenience to the drivers and passers-by of electric vehicles charging in the station.

Preparatory stage of the charging station construction process - entrance and exit

Preparatory stage of charging station construction process, matters needing attention at the entrance and exit of charging station

First, entrances and exits must be easily identifiable, which can be facilitated by prominent signs or architectural symbols.

Second, the entrance should be arranged on a road section with large traffic flow. If it is near a commercial plaza, entertainment facilities, etc., it is necessary to ensure that the number of entrances is sufficient.

Third, open space should be set aside before the entrance and special isolation facilities should be set up to form a "harbour-style" waiting area to avoid affecting road traffic.

Fourth, the exit of the charging station should be arranged on a road section with less traffic, and maintain a specified distance from urban roads, passages, and overpasses.

Fifth, if the site area is large, the entrance and exit can be set up with two lanes, and the traffic organization of right in and right out is adopted.

The preparatory stage of the charging station construction process - determining the pile enterprise

Today, there are many manufacturers of charging piles on the market, but the production standards and product quality are difficult to control. Therefore, to choose a charging pile with reliable quality and stable performance, and choose a powerful large manufacturer, you need to pay attention to the following points when choosing a charging pile manufacturer.

Because the charging pile is an electronic technology product, the production technology of the charging pile manufacturer is very important, which can directly affect the performance of the charging pile during use. To choose a car charging pile manufacturer, it is necessary to understand its specific processing technology, including the raw materials or parts used in the production process and the basis of assembly inspection technology, etc., in order to effectively ensure that the charging pile can cope with changes in various environments and climates. life.

2. Consider the practicability of the manufacturer's charging pile

The use of charging piles is to ensure the travel of electric vehicles, and also to relieve the anxiety of electric vehicle owners, and at the same time, it is convenient for users to get started quickly. When choosing a car charging pile manufacturer, it is not only necessary to consider the practicality of the equipment. It is also necessary to focus on practicality and ease of operation in operation, so as to meet the charging requirements of different models and users.

3. Consider the after-sales situation of the manufacturer

In the process of using car charging piles, it is inevitable that abnormalities will occur due to various factors. Regular manufacturers will have a certain warranty period for charging pile products. Therefore, users should pay attention to the length of the warranty period provided by the manufacturer for charging piles when choosing. Automobile charging pile manufacturers must have perfect after-sales service.
