Abstract: An electrical charging system configured to charge a battery includes a power transmitter, an energy coupling arrangement, an electrical signal shaping device including a controller, and an alignment means. The arrangement includes a first inductive coil disposed external to the vehicle and a second inductive coil attached with the vehicle. The alignment means communicates with the vehicle to ensure repeatable vehicle positioning so that the second inductive coil is positioned relative to the first inductive coil so that the second inductive coil receives the energy produced by the power transmitter wirelessly transmitted from the first inductive coil. The energy received by the second inductive coil is electrically shaped by the electrical signal shaping device and further transmitted through the electrical signal shaping device as controlled by the controller to charge the battery. Methods for transmitting energy through the electrical charging system to charge the battery are also presented.

Abstract: A wireless vehicle battery charging system includes an off-vehicle transducer connected to a power source and configured to wirelessly transmit and receive a first alternating current having a first frequency, an on-vehicle transducer configured to wirelessly transmit and receive the first alternating current, and a frequency converting circuit connected to the on-vehicle transducer. The frequency converting circuit is configured to change the first frequency of the first alternating current to a second alternating current having a second frequency. The system further includes a battery within the vehicle and a regenerative braking circuit connected to the frequency converting circuit and the battery. The regenerative braking circuit is configured to rectify the second alternating current to a direct current supplied to the battery and configured to convert the direct current from the battery to the second alternating current supplied to the frequency converting circuit.
