Roadway Powered Electric Vehicle Performance 830350

The performance of a roadway-powered electric vehicle system was determined by analysis and test. In this system, energy can be transferred efficiently from the roadway to the vehicle by inductive coupling across reasonably large air gaps. Higher frequency, flux density, and road current all improve power density and/or system efficiency. Use of the powered roadway by conventional vehicles is not compromised because drivability and thermal effects are small. No difficulties were uncovered which obviate the desirability of developing the powered roadway as a means to reduce dependence on petroleum.
