Abstract
Electrified roadway systems include a roadway, and vehicles configured to operate on the roadway. The roadway has a base, and two electrically-conductive rails mounted on the base. One of the rails is electrically connected to a source of electric power, and the other rail is electrically connected to an electrical ground. The vehicles include non-electrically-conductive tires, and an electric motor mechanically connected to, and configured to rotate at least one of the tires to propel the vehicle along the roadway. The vehicles draw electric power from the roadway via two electrical pickups that contact the respective rails, and a retracted position at which the pickups are out of contact with the rails. A wear-resistant cover can be positioned on each of the rails. The wear resist covers can have features that maximize the contact area and the contact force between the covers and the rails.
