Description

technical field [0001] The invention belongs to the technical field of charging devices for electric vehicles, and in particular relates to a rotating conductive joint device and a using method thereof. Background technique [0002] At present, large vehicles such as electric buses mainly use charging bows for fast charging. Compared with traditional charging piles, the charging time of charging bows can be shortened from the original 3 hours to 15 minutes, which greatly shortens the charging time and makes electric vehicles It takes only 5 minutes for the bus to quickly replenish its power at the first and last stations. Therefore, the charging method of the charging bow is convenient for dispatching urban bus lines, reducing charging time and reducing the investment of public transport vehicles, and its application is becoming more and more extensive. [0003] Charging bow charging breaks through the limit of the maximum output current of a single gun of 250A stipulated b...

AI Technical Summary

Problems solved by technology

[0005] When the charging plate moves up and down repeatedly, the high-current cable connected to the charging plate also needs to move repeatedly at the same time and bend continuously. Therefore, the cable is constantly bent, which is easy to wear and has a low service life.

In addition, in order to make the cable meet the current-carrying requirements, it is necessary to use a thick-gauge cable. The cable is bulky and has a large bending radius, which makes the charging bow unable to flexibly lift and charge.

In addition, the coordination and appearance of the cable and the bow frame are very unreasonable
