Under the premise of promoting global environmental protection today, the development of new energy vehicles has also driven the development of charging piles. Charging piles are equivalent to refueling machines in gas stations. Different types of cars are different, just like oil.
1. According to installation conditions, it is mainly divided into wall-mounted charging piles, floor-mounted charging piles and portable charging piles.
Wall-mounted charging piles must be fixed against walls, such as indoor parking lots and domestic parking Spaces.
Floor type charging piles do not need to lean against a wall, and are suitable for outdoor parking Spaces, charging stations, etc. Most wall-mounted charging piles can also rely on columns as floor type charging piles.
Portable charging pile free of installation, small size, easy to carry with the car
2. Classified by 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 are generally fully charged within 6-8 hours. They are suitable for small electric vehicles, mostly used in public parking lots and community garages. Household charging piles are also mostly AC charging piles.
Dc charging piles generally have high current, larger charging capacity in a short time and larger pile body. They are suitable for rapid DC charging of electric buses, minibuses and engineering vehicles
3. Classified by voltage grade, it is mainly divided into single-phase charging pile and three-phase charging pile.
There is a phase live line and a phase zero line in the single-phase charging pile, and the voltage between the live line and zero line is 220V.
Three-phase charging pile has three-phase live line, one phase zero line, the voltage between adjacent live line is 380V.
