Abstract

A battery of an electric vehicle is inductively charged while the electrical vehicle is moving, using a magnetic field along different portions of an extended linear distance and an inductive coil mounted on an electric vehicle, by having the electric vehicle, as it traverses the different portions of the extended linear distance, move within the influence of the magnetic field. An apparatus senses progress of the electric vehicle along the extended linear distance. The apparatus produces the magnetic field by a power switch bank connected to an array of inductive coils.
