Common AC charging piles and DC charging piles advantages and disadvantages performance analysis and comparison table

Comparison of several commonly used charging piles

1. The function of the charging pile is similar to that of a gas dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can also be carried mobile in the car and charged at any time and anywhere. In short, it can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to determine the corresponding charging method and charging time. The charging pile display can display data such as charging amount, cost, charging time, etc. UnionPay payment, WeChat, Alipay and other payments can also be made through the background.

2. Charging pile classification: 1) According to the installation method, it can be divided into floor-standing charging piles, wall-mounted charging piles, and mobile portable charging piles. Floor-standing charging piles are suitable for installation in parking spaces not close to walls. Wall-mounted charging piles are suitable for installation in parking spaces close to the wall. Mobile portable charging piles can be carried with the car.

2) According to the installation location, it can be divided into public charging piles and dedicated charging piles. Public charging piles are charging piles built in public parking lots (garages) combined with parking spaces to provide public charging services for social vehicles. Special charging piles are charging piles that are owned by the construction unit (enterprise) and are used by internal personnel of the unit (enterprise). Self-use charging piles are charging piles built in personal parking spaces (garages) to provide charging for private users. Charging piles are generally constructed in conjunction with parking spaces in parking lots (garages). The protection level of charging piles installed outdoors should not be lower than IP54. The protection level of charging piles installed indoors should not be lower than IP32.

3) According to the number of charging interfaces, it can be divided into one-one-charge and one-multiple-charge.

4) According to the charging method, charging piles (plugs) can be divided into DC charging piles (plugs), AC charging piles (plugs) and AC-DC integrated charging piles (plugs).
