Contactless energy transfer between power supply and electric vehicle as described in this proposal is based on the principle of resonant inductive coupling. A pair of charging pads, the stationary charging pad and the mobile charging pad, is used for this purpose. A charging pad may incorporate one or more coils and may be underlaid with material that is capable of conducting the magnetic field. As the stationary charging pad and the inverter are combined to form a unit within the stationary part (though they may be arranged at separate locations), no publicly accessible interfaces are required. The stationary part may be embedded in the ground and mounted flush with the road surface, or it may rest on the ground, e.g., for mounting in a garage. The inverter serves to convert the supply voltage and to set the frequency, current and voltage for the magnetic coil(s) of the stationary charging pad. In addition to the mobile charging pad, the mobile part of the charging eq uipment incorporates the on-board electronics.
