We have been a natural partner for designers and manufacturers of electric vehicle charging stations, providing them with trouble-free cable management solutions for their electric vehicle charging stations around the world. By applying our power springs in retractable cable reels, cable wear is reduced and cables can be neatly stored away when not in use.
The natural tendency of the power spring to expand imparts torque to the mandrel or case, which generates the available torque. The torque generated is cumulative, so the torque increases as the spring preloads and decreases as the spring unwinds.
Torque and a total number of turns are the most important output requirements in power spring design. The performance of a power spring depends on the dimensions of the spring material (thickness, width, and length) and the available space (housing and mandrel diameter).
The cable reel pulls back the middle of the charging cable when the user walks back to the charging end. This makes it easier for the user to return the charging cable to the charging station after completing charging the vehicle. This ensures that the cable is safe for the next electric vehicle to stop and charge.
