AI Technical Summary

Technical Problem

In existing charging equipment, the insulation requirements between the positive and negative wires increase the flow resistance of the cooling medium, which increases the energy required for the cooling medium to flow and poses a short circuit risk.

Method used

Two independent cooling circuits are used for cooling the positive and negative conductors respectively. Insulation is ensured through independent cooling medium channels and driving components, and insulation structures are set in the heat exchanger and expansion tank to reduce the risk of short circuit.

Benefits of technology

It reduces the flow resistance of the cooling medium, reduces the energy required for the cooling medium to flow, improves cooling efficiency, reduces the risk of short circuits, and meets insulation requirements and hydrogen safety.

Abstract

The embodiment of the application provides a charging device, and relates to the technical field of charging. The charging device comprises a charging connector, a cable and a cooling assembly. The charging connector is used for connecting a device to be charged. The cable comprises a positive electrode wire, a negative electrode wire, a positive electrode flow channel and a negative electrode flow channel. The positive electrode wire and the negative electrode wire are connected to the charging connector. The positive electrode wire is at least partially located in the positive electrode flow channel, and the negative electrode wire is at least partially located in the negative electrode flow channel. The positive electrode flow channel and the negative electrode flow channel are not communicated with each other. The cooling assembly comprises a first driving member and a second driving member which are insulated from each other. The first driving member is communicated with the positive electrode flow channel. The first driving member is used for driving a first cooling medium to flow in the positive electrode flow channel and the first driving member. The second driving member is communicated with the negative electrode flow channel. The second driving member is used for driving a second cooling medium to flow in the negative electrode flow channel and the second driving member.
