What are the types of charging piles?

Charging piles can be classified from multiple dimensions. The following is a detailed classification:

1. Classification according to installation conditions

1. Vertical charging pile: no need to lean against the wall, suitable for outdoor parking spaces or community parking spaces.
2. Wall-mounted charging pile: It must be fixed on the wall and is suitable for indoor and underground parking spaces.

2. Classification according to the protection level of the installation location

1. Indoor charging piles: installed in indoor environments, such as underground parking lots, etc.
2. Outdoor charging piles: Installed in outdoor environments, they require a higher level of protection to cope with various weather conditions.

3. Classification by service objects

1. Public charging piles: purchased by government agencies and other public service institutions, and the service targets any electric vehicle owners, such as public parking lots.
2. Special charging pile: The construction unit (enterprise) has its own parking lot (garage) and is a charging pile used by internal personnel of the unit (enterprise).
3. Self-use charging pile: A charging pile built in an individual's own parking space (garage) to provide charging for individuals.

4. Classification by charging type

1. AC charging piles: generally have low current, small pile body, and flexible installation. It usually takes 6-8 hours to fully charge. They are mostly used in public parking lots, large shopping malls and community garages. Most household charging piles are AC charging piles.
2. DC charging pile: Directly connected to the power grid, it can directly charge the battery of electric vehicles. It generally uses a three-phase four-wire system or a three-phase three-wire system for power supply. The output voltage and current have a wide adjustable range, which can realize fast charging of electric vehicles.
3. AC-DC integrated charging pile: It can realize both DC charging and AC charging. For example, when the charging demand is high during the day, DC charging can be used for fast charging, and when there are few charging users at night, AC charging can be used for slow charging.

5. Classification according to the number of charging interfaces

1. One charging station: one charging station only charges one electric vehicle.
2. One charging pile for multiple charging: One charging pile with multiple interfaces can charge more than one electric vehicle at the same time. This kind of charging pile is more common in large parking lots such as bus parking lots, which can improve charging efficiency and save labor.

In addition, the structure of the charging pile includes the shell, controller, charging module, display screen, cables and safety protection devices. The quality and performance of these parts directly affect the charging efficiency and safety of the charging pile. When designing and manufacturing charging piles, attention to detail and quality control of each part is required.

All in all, there are many types of charging piles, which can be selected according to different needs and application scenarios.
