Abstract
A cable reel assembly in an electric vehicle supply equipment (EVSE) having a reel around which a cable is coiled. A shaft supporting the reel bears discs that rotate with the reel, and calipers coupled to the discs stop them and the reel from rotating. The power L1 and L2 conductors in the cable are electrically connected to the discs, and the calipers are electrically connected to the power source for the EVSE so that the calipers provide mechanical and electrical connection when actuated. Optionally, slip rings coupled to the shaft are connected to the control pilot and proximity signal conductors in the cable. Thus, during cable re traction, the control pilot and proximity signals are still provided to the EVSE, but the power conductors are decoupled from the power source. Only when the calipers are actuated to brake the discs is current flow permitted.
