How to distinguish AC and DC charging piles on the street

China [CN]

Charging pile is one of the facilities for electric vehicles to supplement electric energy. According to the types of AC charging pile and DC charging pile, it can be called "slow charging" and "fast charging". As the interaction between the charging pile and the electric vehicle, the charging cable plays an important role. With the gradual increase of the total amount of electric vehicles on the social road, DC charging piles are more popular with consumers, which is the reason for shortening the charging time of electric vehicles and facilitating charging.

Then, the difference between AC charging pile and DC charging pile

AC charging pile refers to a special power supply device that provides AC power to electric vehicles with on-board chargers by conduction.

The DC charging pile is a power supply device that is fixed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the off board electric vehicle power battery. The input voltage of the DC charging pile is three-phase four wire AC380V ± 15%, and the frequency is 50Hz. The output is adjustable DC, which directly charges the power battery of electric vehicles. As the DC charging pile adopts the three-phase four wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a wide range, which can meet the requirements of fast charging. The three-phase 380V AC enters the three-phase four wire meter after passing through the lightning protection filter module such as EMC. The three-phase four wire meter monitors the actual charging amount of the whole charger when it is working. One DC charging pile has a large current of 1500V, which generates a large amount of heat, so the wires are relatively thick. The DC charging pile is a power supply device that is fixed outside the electric vehicle and connected to the AC power grid and can provide DC power for the power battery of the off board electric vehicle.

DC charging pile cable is a special charging pile cable with oil resistance, chemical resistance, acid and alkali resistance, high temperature resistance, high voltage resistance, water resistance and electromagnetic interference prevention; This product has good concentricity, high flexibility and stable and reliable performance, and is one of the choices for outdoor charging piles.

No matter which type of charging pile consumers choose, they need to choose the appropriate charging cable, and realize the high efficiency of charging electric vehicles through the combination of charging modes of electric vehicles.
