Technical Field

[0001] The present invention relates to the technical field of direct current liquid-cooled charging piles, and in particular to a liquid-cooled charging pile CDU driving device. Background Art

[0002] At present, the charging gun and the cable have completed the working functions in the structural test and can work normally. Now how to solve the problem of how to solve the working of the charging pile CDU drive device has become a difficult problem. How to make the charging gun line and the charging pile CDU drive device work together as one. For example, when the production line is in production, the DC+ / DC- two main lines need liquid cooling and cooling. However, in the production process, it is difficult to achieve higher automation production. It is easy to reverse the liquid cooling inlet and outlet pipes of the DC+ / DC- two main lines. After the reverse connection, they cannot work normally. In severe cases, the charging pile CDU drive device will be scrapped. In response to this problem, the present invention has carried out long-term experiments. By installing software monitoring in the charging pile CDU drive device, modifying the internal structure of the charging pile CDU drive device, and making structural changes to the inlet and outlet circuits of the drive device structure, the charging gun line and the charging pile are finally solved and realized to work together as one.

[0003] Existing technical solutions: Although the charging gun line manufacturer has developed a liquid cooling structure, the coordination of the charging piles has ultimately failed to complete the work, forming a bottleneck problem. During the test, there were problems such as "reverse driving in the high-speed lane", "too high temperature", and "temperature cannot be lowered". Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a liquid-cooled charging pile CDU drive device, in which software monitoring is installed in the charging pile CDU drive device, the internal structure of the charging pile CDU drive device is modified, and the input and output circuits of the drive device structure are structurally modified.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a liquid-cooled charging pile CDU drive device, comprising a charging pile body, an inner cavity of the charging pile body is provided with a liquid-cooled drive device, a charging gun line is fixedly connected to the right side of the liquid-cooled drive device, and a charging gun is fixedly connected to one end of the charging gun line away from the liquid-cooled drive device.

[0006] Preferably, the inner cavity of the charging gun line is provided with two cooling medium return channels.

[0007] Preferably, the inner cavity of the charging gun line is provided with two cooling medium inlet channels.

[0008] Preferably, the charging gun is located on the right side of the charging pile body.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention allows the charging gun line and the charging pile body to fully cooperate to form a complete flow path loop monitoring point, which fully solves the correct working state of the three-in-one of the charging gun when charging new energy vehicles, avoids bottleneck problems such as "reverse driving in the high-speed lane", "too high temperature", and "temperature cannot be lowered", thereby achieving the satisfaction of the new national standard, and finally achieving a true liquid-cooled charging mode in which the car is charged with a charging gun when only 20% of the power is left, and it only takes about 5 minutes to charge to more than 80%.
