There are three traditional methods of supplying propulsion energy to electric vehicles: sliding electrical contacts, festooned or coiled electrical cables, and energy stored in batteries. Recent innovations and developments have added a fourth practical method, the inductively coupled roadway power system. Incentives to make use of the inductive roadway powered vehicle system include extended vehicle range, low operating cost, compatability with existing systems, electrical safety, and adaptability to automation. Certain characteristics of the system should be understood by vehicle and system designers in order to realize and optimize these benefits in the various applications to which the system is suited. Key design parameters of inductively coupled power systems are the current and frequency in the roadway power conductor, and the geometry of the magnetic circuit. These parameters strongly influence the amount of power that can be coupled, and the range of airgap (clearance) variations in the coupling and guidance errors that can be tolerated. The relationship of the system's characteristics to selected potential applications is explored briefly.
