It is mainly divided into AC charging pile and DC charging pile.
AC charging piles are generally small current, small pile body, flexible installation, and fully charged in 6-8 hours. They are suitable for small passenger electric vehicles. They are mostly used in public parking lots, large shopping centers and community garages. Household charging piles are also mostly AC charging piles. The DC charging pile is generally high current, with larger charging capacity in a short time, larger pile body and large occupied area (heat dissipation). DC charging pile is suitable for fast DC charging of electric buses, medium buses, hybrid buses, electric cars, taxis, engineering vehicles, etc.
It is mainly divided into public charging pile, special charging pile and self-use charging pile.
Here is just a distinction between the uses of charging piles. The charging piles of different service objects can also have their roles interchanged. The public charging pile is purchased by government agencies and other institutions with the nature of public services, and the service object is for any electric vehicle owner, such as public parking lot. Most of the special charging piles are built by enterprises, and the service objects are customers and internal personnel, such as shopping malls and parking lots. The self use charging pile is a private charging pile, which is installed in the private field and is not open to the public.
It is mainly divided into indoor charging pile and outdoor charging pile.
The protection grade of the indoor charging pile should at least reach IP32, while the outdoor charging pile needs to face the harsh environment of wind and rain, and needs better insulation and lightning protection conditions. Its protection grade should at least reach IP54 to ensure personal safety, body safety and charging equipment safety.
At present, the charging piles in the market are mainly one pile and one charging. In large parking lots such as bus parking lots, multiple charging piles are needed to support the charging of multiple electric vehicles simultaneously, which not only speeds up the charging efficiency but also saves labor.
