Common specifications of DC charging pile cables

According to the data, DC charging piles are power supply devices that are fixedly installed outside electric vehicles and connected to the AC power grid. They can provide DC power for off-board electric vehicle power batteries. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, frequency 50Hz. The output is adjustable direct current, which directly charges the power battery of the electric vehicle.

Among them, because the DC charging pile adopts a three-phase four-wire system for power supply, it can provide sufficient power, and the output voltage and current adjustment range are large, which can meet the requirements of fast charging. The three-phase 380V alternating current enters the three-phase four-wire ammeter after passing through EMC and other lightning protection filter modules. The three-phase four-wire ammeter monitors the actual charging power of the entire charger when it is working. A DC charging pile has a high current of 1500V and generates a lot of heat, so the wires are relatively thick. The DC charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid. It can provide DC power for the off-board electric vehicle power battery. .
