The charging pile is characterized by comprising a controller, a power conversion module and the charging pile self-expansion device according to any one of claims 1 to 8, wherein the input end of the power conversion module is connected with an external power grid, the output end of the power conversion module is connected with the wire inlet end of the conductive slip ring, the controller is in communication connection with the power conversion module, and the output end of the controller is connected with the input end of the driving assembly.
10. A charging method, characterized in that the charging pile according to claim 9 is used, comprising:
Acquiring charging demand information and current charging cable information, wherein the charging demand information comprises a target paying-off length of a charging cable, and the current charging cable information comprises a current outgoing length of the charging cable;
Calculating a target telescopic length according to the target paying-off length and the current outgoing length;
According to the target telescopic length, the driving assembly is controlled to operate so as to drive the turntable group to rotate, the line pressing block rotates along with the turntable group to approach or depart from the center of the turntable group, and the line pressing block always abuts against the surface of the charging cable on the outermost ring, so that the rotation amount of the driving assembly is positively correlated with the outgoing line length of the charging cable until the current outgoing line length reaches the target paying-off length, and the winding or paying-off of the charging cable is completed.
