The function of the charging pile is similar to the refueling machine in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential quarters parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform operations such as the corresponding charging method, charging time, and cost data printing. The charging pile display screen can display data such as charging capacity, cost, and charging time.

The function of the charging pile

The charging pile (bolt) can be used for timing, metering, and metering charging, and can be used as a terminal for citizens to purchase electricity. At the same time, in order to improve the efficiency and practicability of public charging piles (bolts), the functions of a pile (bolt) for multi-charging and charging electric bicycles will be gradually added in the future.

Types of charging piles

According to the installation method

It can be divided into floor-mounted charging piles and wall-mounted charging piles. Floor-standing charging piles are suitable for installation in parking spaces that are not close to the wall. Wall-mounted charging piles are suitable for installation in parking spaces close to the wall.

According to installation location

According to the installation location, it can be divided into public charging piles and special charging piles. Public charging piles are built in public parking lots (garages) combined with parking spaces to provide public charging services for social vehicles. The dedicated charging pile is the self-owned parking lot (garage) of the construction unit (enterprise) and is used by the internal personnel of the unit (enterprise). Self-use charging piles are built in personal parking spaces (garages) to provide charging for private users. Charging piles are generally combined with the construction of parking spaces in parking lots (garages). The protection level of charging piles installed outdoors should not be lower than IP54. The protection level of charging piles installed indoors should not be lower than IP32.

According to the number of charging ports

It can be divided into one charge and one charge.

According to charging method

Charging piles (bolts) can be divided into DC charging piles (bolts), AC charging piles (bolts) and AC and DC integrated charging piles (bolts).

Safety requirements for charging piles

(1) The substation shall be equipped with safety fences, warning signs, safety signal lights and alarm bells.

(2) A warning sign of "Stop, High Voltage Danger" should be hung outside the door of the high-voltage power distribution room and the transformer room or on the safety column of the substation. The warning signs must face the outside of the fence.

(3) The high-voltage power distribution device should have obvious operating instructions. The grounding point of the equipment should be clearly marked.

(4) There should be obvious signs of "safe passage" or "safe exit" indoors.

In addition, the layout design of the substation and power distribution equipment should be convenient for installation, operation, handling, maintenance, testing and monitoring. High and low voltage power distribution rooms, transformer rooms, capacitor rooms, and control rooms should not have any pipes and lines that have nothing to do with them. Of course, even if the technical bottleneck of the charging station is well resolved, there may still be problems such as difficulty in site selection for the construction of the charging station. New energy vehicles should focus on cities first, but the prosperous Ⅸ area often has a shortage of land, and the cost of land prices is high. In this regard, the government needs to be able to tilt it in policy. Promote the construction of charging facilities. The development and operation of electric vehicle charging stations by power companies has inherent advantages. It is a new business for electric power companies to sell electricity directly to vehicles, and it is hoped that power companies can change
