An electric vehicle is supplied with power from a power supply via a cable suspended from an anchor. The anchor is attached to a mount on the vehicle and detachable from the mount by tension in the first portion of the cable between the anchor and the power supply. A second portion of the cable between the anchor and the vehicle remains slack in the attached position of the anchor, and extends on detachment of the anchor to relieve tension in the first portion of the cable. A disconnection switch is operable by detachment of the anchor to interrupt the power supply from the cable to the vehicle.
