Problems solved by technology
[0003] In the related art, the heat dissipation of the charging terminal is mainly through the soft wire and the shell connected between the charging terminal and the terminal to transfer heat out. Since the whole is a closed structure, the heat transfer speed is too slow and the efficiency is low.
If the heat dissipation effect is improved by thickening the wire diameter of the integrated cable soft wire, the integrated cable wire diameter of the connecting terminal will become very thick (GB / T 11918.1-2014 nominal current 400A conductor cross-sectional area is 240mm 2 ), the soldering process between the overly thick cable wire and the charging terminal is also difficult, and even if it is connected, the overall weight of the integrated cable is inconvenient to operate, the cost will be high, and the heat dissipation effect is not very ideal

The invention discloses a charging base and a charging system. The charging base includes a wiring harness terminal group, a charging terminal group and an insulating part; the charging terminal groupis provided with a containing slot, and the charging terminal group is electrically connected to the wiring harness terminal group; and the insulating part is at least partially arranged in the containing groove, the insulating part communicates with a liquid inlet pipe and a liquid outlet pipe, the wiring harness terminal group and the liquid inlet pipe and / or the liquid outlet pipe, and coolingliquid flows from the liquid inlet pipe into the insulating part and then flows out from the liquid outlet pipe. The charging base has the good heat dissipation effect and low cost.
Description
technical field [0001] The invention relates to the technical field of DC charging sockets for electric vehicles, in particular to a charging stand and a charging system. Background technique [0002] With the popularization of new energy electric vehicles, the application of charging equipment is becoming more and more extensive, and some new technical problems have emerged. Among them, the greater the current of the charging stand, the thicker the cables are, and the flexibility is limited, resulting in insufficient space inside the car body. In the process of DC charging (high power 1000V / 400A and above), the heat generated by the charging terminal is particularly large, and it is necessary to quickly cool down the charging terminal to transfer the heat. [0003] In the related art, the heat dissipation of the charging terminal is mainly through the soft wire and the shell connected between the charging terminal and the terminal to transfer heat out. Since the whole is a...
