The technical principle of DC charging pile
The DC charging pile (or non-vehicle charger) is fixedly installed outside the electric vehicle and connected to the AC grid, and directly outputs adjustable DC power to charge the vehicle battery. The output voltage and current have a large adjustment range, large power, and fast charging speed. Fast, commonly known as "fast charge".
The output of the DC charging pile consists of 9 wires, which are:
1. DC power supply line: DC+, DC-;
2. Equipment ground wire: PE;
3. Charging communication lines: S+, S-;
4. Charging connection confirmation lines: CC1, CC2;
5. Low-voltage auxiliary power supply lines: A+, A-;

Charging Pile Relay Introduce:
The relay is a control element, a circuit switch with protective performance, and the core component of the new energy charging pile. Relays are mainly used for on-off switches of low-voltage remote control high-voltage circuits (using safe low-voltage 12V-72V to control unsafe high-voltage 300V-1000V). Usually used in automatic control circuits, it is actually an "automatic switch", which uses small currents to control the action of large currents, forming a safety protection mechanism and switching circuits and other components in the circuit. Fast action, small size, high arc extinguishing safety, high operation reliability, and long service life.
