Location selection of automobile charging pile installation requirements
1. A safe distance should be ensured between the electric vehicle and the automobile charging pile: when the automobile charging pile is installed on the side of the vehicle and does not hinder the door opening, the clear distance between the outer contour of the automobile charging pile (including anti-collision facilities) should not be less than 0.4m；; When the door is blocked from opening, the clear distance between the outer profile of the automobile charging pile (including anti-collision facilities) and the electric vehicle should not be less than 0.6m.
2. When the automobile charging pile is installed at the rear of the vehicle, the clear distance between the outline of the automobile charging pile (including anti-collision facilities) and the electric vehicle should not be less than 0.5m. At present, when designing garage parking spaces, architecture majors usually have a width of 2.4~2.5m and a length of 5.5~6m. Generally, the width of electric passenger cars is about 1.8m, and the length of cars is less than. It can be seen that it is difficult to meet the specification requirements if charging facilities are set on the side of ordinary parking spaces. It is suggested that when arranging parking spaces with slow piles, priority should be given to setting parking spaces with partition walls at the back of the vehicle perpendicular to the carriageway as slow piles, setting wall-mounted slow piles at the rear of the vehicle, and setting rear wheel stops at the parking spaces to ensure safety and avoid accidents when people operate charging facilities, which can make full use of space and facilitate the arrangement of parking spaces. If a complete set of electrical equipment manufacturers need to set charging facilities on the side of vehicles, they should fully consider the size and spacing requirements of charging facilities when designing, and cannot simply set them according to the size of ordinary parking spaces.
3. When setting charging piles, designers should pay attention to the convenience and safety of actual operation. The parking space with slow filling piles should be equipped with pillar-type slow filling piles at the rear of the car, which can avoid unfavorable factors and facilitate practical use. For example, when setting in outdoor public areas, complete electrical equipment manufacturers may consider setting in combination with green belts, but attention should be paid to the influence of surrounding vegetation and irrigation facilities. For example, it is not advisable to plant tall trees around to reduce the harm caused by lightning strikes, and at the same time avoid hindering the maintenance of vegetation. Generally, the power of the fast-filling pile is relatively high, so it should be set centrally and close to the transformer to reduce the line loss, which is mainly used for supplementary and emergency charging. It can be considered to be set in an area convenient for access and management to improve the utilization rate and facilitate timely maintenance and emergency treatment.
In addition, the designer should reasonably set the number and area of fast and slow charging according to the main customer groups. For businesses, hospitals, restaurants, entertainment and other places, people flow frequently, and the per capita stay time is relatively short and not fixed, so the demand for fast charging is more urgent. However, the staff in offices, schools, hotels and other places are relatively fixed, and the stay time is relatively stable. Users can fully estimate the required charging time. If there is no special requirement for charging time, consider setting up more slow charging. Complete electrical equipment manufacturers, especially in the design of complex projects, should fully consider the distribution of business formats, optimize the layout of fast and slow charging parking spaces for customer groups, reduce the idleness of charging piles and improve the user experience.
