Claim:
1. An apparatus for alignment, verification and/or optimization of charging coils in an electric vehicle charging system comprising: (a) first and second charging coil units disposed in spaced-apart relation to each other, the first charging coil unit coupled to an electrical energy source and the second charging coil unit coupled to an electric load that is a battery; (b) a guideway sub-assembly including a drive mechanism configured to translate the first charging coil unit in X-, Y-, and Z-directions; (c) a sensor sub-assembly for sensing the position of the coil units relative to each other, the sensor sub-assembly including electromagnetic field signal means; (d) translational drive means actuated by servo drives connected to an electrical power source for moving the first charging coil unit in the X-, Y-, and Z-directions relative to the second charging coil unit; (e) rotational drive means actuated by motor means for moving the first charging coil unit in an angular orientation about the X-, Y-, and Z-axes of the second charging coil unit; and (f) a system controller connected to an electrical power source and to the translational and the rotational drives means, the system controller being configured to manage, control and direct the movements of the first and the second charging coil units.
