Charging cable management system
The present invention concerns a charging cable management system, which is motorized and is applied in electric vehicle charging equipment, or other applications that require this type of solution. The developed charging cable management system allows extending or retracting a suspension cable that assists the user in the task of mobilizing and moving an electric charging cable for charging electric vehicles, preventing it from touching the ground when not in use. In addition, the charging cable management system allows the use and mobilization of charging cables with greater longitudinal amplitude, minimizing the efforts associated with carrying out these tasks by the user.
