1. An apparatus for charging batteries of a moving electric vehicle comprising:

  • (A) an electromagnetic strip means for producing a magnetic field along a centerline of a roadway, comprising a series of inductive coils, power supply line, switches, and sensors;

    (B) an armature and armature drive motor servo mechanism for transducing the magnetomotive force of said magnetic field to electromotive force, producing electric current for charging said batteries;

    (C) a level controller and level controller servo mechanism means for positioning said armature in optimum proximity to said magnetic field wherein(C1) the level controller including a road hazard protection means comprising;

    (C1-1) an armature mounting plate;

    (C1-2) lowering arms means for manipulating the mounting plate;

    (C1-3) a level control arm and a level control arm shield;

    a shock absorber means for connecting said level control arm to said lowering arms means for protecting the armature mounting plate and the armature from said hazards(C1-4) a worm gear means for operating the lowering arms means;

    (C2) the level controller servo mechanism comprising;

    (C2-1) a magnetic field intensity sensor, a potentiometer, and a reversible servo motor for driving said worm gear means for maintaining optimum proximity of said armature to said magnetic field;

    (D) a ratchetted safety release hub means for emergency disengagement of said worm gear means from a servo motor shaft;

    (E) an antimagnetic shield means for protection of electric vehicle passengers and electronic equipment;

    (F) means for identifying, timing and billing said vehicle for battery charging service.
