The invention belongs to the technical field of electric vehicles and particularly relates to an electric vehicle safety charging station with the high charging gun utilization rate and low manufacturing cost. The charging station is composed of two or more charging circuits corresponding to mechanical storage device hangers in number. Each charging circuit is composed of a charging gun and a charging cable. The charging circuits are connected with a power distribution cabinet. A mechanical storage device comprises a high overhead rail and a tension spring balancer, wherein two or more sliding hanging wheels are installed on the high overhead rail, the sliding hanging wheel on the side close to the charging guns is connected with the tension spring balancer. The tension spring balancer is connected with the charging guns or the charging cables connected with the charging guns. The sliding hanging wheel on the side close to a power distribution cabinet is connected with the charging cables. According to the charging station, the charging gun using efficiency is greatly improved, the manufacturing cost of the charging station is greatly decreased, and the maintenance cost is greatly decreased; the charging guns and the charging cables will not touch the ground all the time, and the safety can be improved.

A cable retractor enclosure having a weighted cable pulley and cable pulley guide rails The cable pulley is rotatable about a pivot and configured to translate along grooves when a cable wrapped underneath is extracted from the cable retractor enclosure The cable extends outside of the retractor enclosure from its upper end and provides a cable end plug that sits within a retractor module insert Weights may be attached to the cable pulley in order to leverage gravitational forces, which result in a bias causing the cable to retract back into the enclosure Friction forces against the extracted cable can be used to prevent the gravitational bias the cable pulley exerts (retraction forces) on the cable by bending the cable to lay flat onto a table surface

A cable management system for an electric vehicle (EV) charging station comprises an upstanding enclosure having a cable opening though which an EV charging cable can be pulled for extension. The EV charging cable is provided at a free end thereof with an EV charging connector for connection with an EV charging socket of an EV. The EV charging cable is provided at an opposed fixed end thereof with an electric connector for connection with a mating connector mounted inside the enclosure. A fixed pulley is mounted within the upstanding enclosure for rotation about a first axis normal to an upstanding axis of the enclosure. The system further comprises a mobile pulley rotatable about a second axis parallel to the first axis. The mobile pulley is vertically translatable within a guiding structure mounted inside the upstanding enclosure for movement towards and away from the fixed pulley. The fixed pulley is mounted at a higher elevation than the mobile pulley. The EV charging cable extends over the fixed pulley and the mobile pulley between its opposed free and fixed ends. The mobile pulley is moveable against gravity from a lowered position to a raised position by the application of a sufficient pulling force at the free distal end of the EV charging cable. The mobile pulley returns at least partly under gravity to its lowered position upon release of the EV charging cable, thereby automatically retracting the cable inside the upstanding enclosure.
