[0002] A charging pile is a device that provides electrical energy to electric vehicles. It is also called an electric vehicle charging station or electric vehicle power supply equipment. It can store enough electricity for electric vehicles to support their operation. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] The traditional charging pile cable storage structure includes a storage box, a winding wheel and a motor.
