According to the installation method

Can be divided into floor-standing charging piles, wall-mounted charging piles. Floor-standing charging posts are suitable for installation in parking spaces that are not close to the wall. The wall-mounted charging pile is suitable for installation in a parking space close to the wall.

By installation location

According to the installation location, it can be divided into public charging piles and special charging piles. The public charging pile is a charging pile built in a public parking lot (library) combined with parking berths to provide public charging services for social vehicles. The special charging pile is a charging pile used by the construction unit (enterprise) own parking lot (library) for the internal personnel of the unit (enterprise). The self-use charging pile is built in a personal own parking space (library) to provide charging stations for private users. The charging pile is generally constructed in conjunction with the parking space of the parking lot (library). The charging post installed outdoors should not be less than IP54. The charging pile installed indoors should not be less than IP32.

According to the number of charging interfaces

Can be divided into one charge and one charge.

By charging method

The charging pile (plug) can be divided into a DC charging pile (plug), an AC charging pile (plug) and an AC-DC integrated charging pile (plug).

Construction requirements

As the electric vehicle charging pile (plug) on the electric side of the power grid, the particularity of its structure determines that the characteristics of the automatic communication system are that the points to be measured are large and scattered, the coverage is wide, and the communication distance is short. And with the development of the city, the network topology requires a flexible and expansive structure. Therefore, the choice of the communication mode of the electric vehicle charging pile (plug) should consider the following problems:

(1) Reliability of communication – Communication systems must withstand harsh environments and strong electromagnetic interference or noise interference for a long time, and keep communication open.

(2) Construction costs – comprehensive consideration of construction costs and long-term use and maintenance costs, provided that reliability is met.

(3) Two-way communication - not only can the upload of information, but also the release of control volume.

(4) Multi-service data transmission rate - With the continuous increase of terminal traffic, the communication between the primary station and the sub-station and the sub-station to the terminal has higher and higher requirements for realizing the data transmission rate of multiple services.

(5) Communication flexibility and scalability - Because charging piles (plugs) have the characteristics of multiple control points, wide area and dispersion, standard communication protocols are required, along with the development of "ALL IP" network technology trends As well as the continuous growth of power operation business, it is necessary to consider the IP-based service bearer, and at the same time require easy installation, commissioning, operation, and maintenance.
