10. A method of charging energy storage systems within a plurality of vehicles each with a receiver coil located on top of the vehicle, said method comprising:
-
providing an inductive power transfer system for inductively transferring power to a receiver coils; positioning the inductive power transfer system above a selected one of the plurality of vehicles and in alignment with the receiver coil in that selected vehicle; after positioning the inductive power transfer system above the selected one of the plurality of vehicles, inductively transferring power from the inductive power transfer system into the selected vehicle through the receiver coil on top of the selected vehicle; and sequentially repeating the positioning and inductive power transfer steps for each of the remainder of the plurality of vehicles.
