However, the user often can not receive and release the loaded down with trivial details cable according to the standard after charging, and places the charging cable beside the charging pile at will. Especially for the direct current fill electric pile fast, its cable is thick and bulky, and is inflexible, and it is more difficult that manual work accomplishes receiving and releasing of cable. The charging cable is placed randomly, so that the charging cable is exposed to the natural environment for a long time, the aging and the abrasion of the charging cable are accelerated, and the charging cable is easy to be broken by various unexpected external forces, such as treading by personnel, rolling by automobiles and the like. Since the cable voltage is a high-voltage charge, once the leakage behavior caused by the wear of the cable sheath is not obvious. At present, the winding and unwinding device for the alternating-current charging pile is occasionally seen in the market, and due to the fact that the alternating-current charging pile is thin in cable, required bending force is small, winding and unwinding are easy, the bending radius of the alternating-current charging cable is small, and the winding and unwinding device is easy to realize in structural design and compact in structure.
