Electric car charging piles are fixed structures on the ground that provide AC electric energy for electric cars with on-board chargers using special charging interfaces and conduction modes. They have corresponding communication, charging, and safety protection functions. (How to Charge an EV imported from China)
The maximum charging power of an AC charging pile is 7KW. The charging power of a DC charging pile is generally 60KW to 80KW. The input current of a single gun on a charging pile can reach 150A--200A. This is a significant demand on the power supply line. In some old communities, even installing one may not be possible.
For public places such as public parking lots, public charging stations, shopping malls, and theaters, it is more convenient to install DC charging piles. When it comes to home charging piles, considering the cost, most of the charging piles for household cars are AC piles.
Because the DC charging pile can directly charge the battery of the electric vehicle, generally adopts three-phase four-wire system or three-phase three-wire system power supply, and the output voltage and current can be adjusted in a wide range, so that the electric vehicle can be quickly charged, and the DC charging pile is also used.
1.Charging pile refers to a charging device with a charging gun and a human-machine interface, which is simply an electrical device that can be charged, either in one piece or in a split type.
