Relays of electric vehicle charging piles and their zero-crossing inspection arc-extinguishing circuits, relays and zero-crossing inspection arc-extinguishing circuits, zero-crossing inspection arc-extinguishing circuits include current limiting circuits, disconnecting transformer T1, resistance pages, differential expansion circuits, and voltage dividers Circuit, microcontroller U2, drive circuit, one end of the commercial power continuous current limiting circuit, the other end of the current limiting circuit continuously disconnects the primary side of the transformer T1, and the secondary side of the transformer T1 continues to one end of the resistance circuit, and the other end of the resistance circuit One end of the continuous differential expansion circuit, the other end of the differential expansion circuit continues to one end of the voltage divider circuit, the other end of the voltage divider circuit continues to the input terminal IN of the single-chip microcomputer U2, and the output terminal OUT of the single-chip microcomputer U2 continues to drive one end of the circuit, the drive circuit The other end of the relay continues to relay, and the mains goes through the relay output; the resistor page continues to have the bias voltage VDD, and the relay continues to have the power supply voltage VCC. The circuit layout is simple, the components are few, the circuit power consumption is small, and the cost is thrifty.

Portable electric vehicle charging pile, the layout includes emergency stop button, touch screen, card swiping area, panel, housing, wiring port, first heat dissipation hole, continuous line, charging plug, gun socket, handle, second heat dissipation hole, guide Lamps, solar panels, emergency stop buttons are arranged on the housing, the touch screen is continuous with the panel, the card swiping area is continuous with the panel, the panel is arranged on the housing, the wiring port is arranged on the lower right side of the housing, and the first heat dissipation hole is arranged on the housing On the right side of the body, the handle is continuous with the upper right of the housing, the guiding light is continuous with the housing, and the solar panel is continuous with the housing. The favorable result: the layout is equipped with solar panels, which can experience solar panel heat collection in a good weather environment. Convert it into electrical energy and charge the charging pile, thereby reducing the use of power resources, using environmental protection, and reducing the use of power resources.
