LIQUID COOLING CHARGING CONNECTOR, LIQUID COOLING CONNECTOR, LIQUID COOLING DEVICE, AND ELECTRIC VEHICLE

This application provides a liquid cooling charging connector, a liquid cooling connector, a liquid cooling device, and an electric vehicle. The liquid cooling charging connector is configured to connect to the electric vehicle. The liquid cooling charging connector includes a housing, a liquid cooling plug, and an electric plug. The housing includes a bottom plate, the bottom plate includes a plurality of jacks, and both the liquid cooling plug and the electric plug pass through the bottom plate through different jacks. The liquid cooling plug includes a liquid supply plug and a liquid return plug. The liquid supply plug is configured to transmit coolant of a liquid cooling unit to the electric vehicle, and the liquid return plug is configured to transmit, to the liquid cooling unit, the coolant output by the electric vehicle. The electric plug includes a connection confirm plug. The connection confirm plug is configured to connect to a connection confirm socket of the electric vehicle. The connection confirm plug is further configured to connect to a connection confirm circuit. A voltage at a detection point in the connection confirm circuit indicates a state of a connection between the liquid cooling charging connector and the electric vehicle. The bottom plate includes a plurality of spaced accommodation cavities, and the liquid cooling plug and the electric plug are located in different accommodation cavities.
