1. According to installation conditions, it is mainly divided into vertical charging pile and wall mounted charging pile.  

Vertical charging pile does not need to be against the wall, which is suitable for outdoor parking Spaces or residential parking Spaces, while wall-mounted charging pile must be fixed by the wall, which is suitable for indoor and underground parking Spaces.  

2. According to the service object, it is mainly divided into public charging pile, charging pile and self-use charging pile.  

This is just a distinction of the use of charging piles, and the roles of charging piles of different service objects can be reversed.  Public charging piles and other institutions with the nature of public services, the service target for any electric vehicle owners, such as public parking lots.  Charging piles are mostly built for enterprises, serving customers and internal personnel, such as parking lots in shopping malls.  Self-use charging pile is private charging pile, installed in the private field, not open to the public.  

3. According to the installation location, it is mainly divided into indoor charging pile and outdoor charging pile.  

The protection level of indoor charging pile should be at least IP32, while the protection level of outdoor charging pile should be faced with the harsh environment of wind and rain, and better insulation and lightning protection conditions are required. The protection level of indoor charging pile should be at least IP54 to ensure personal safety, body safety and charging equipment safety.  

4. According to the number of charging interfaces, it is mainly divided into one charging pile and one multi-charging pile.  

At present, the charging pile on the market is mainly a pile and a charging type. In such a large parking lot as the bus parking lot, multiple charging piles are needed to support multiple electric vehicles charging synchronously, which not only speeds up the charging efficiency, but also saves labor.  

5. According to the charging type, it is mainly divided into AC charging pile and DC charging pile.  

Ac charging piles generally have small current, small pile body, flexible installation, and a full charge in 6-8 hours. They are suitable for small passenger electric vehicles and are mostly used in public parking lots, large shopping centers and community garages. Household charging piles are also mostly AC charging piles.  However, DC charging piles generally have high current, with larger charging amount in a short time, larger pile body and larger occupied area (heat dissipation).  Dc charging pile is suitable for fast DC charging of electric buses, Pakistan buses, hybrid buses, electric cars, taxis, engineering vehicles, etc.
