An electrical charging system configured to wirelessly charge an energy storage device, such as a battery. The charging system includes an off-transducer in electrical communication with an alternating power source and electromagnetically coupled to an on-vehicle transducer connected to the energy storage device. A controller adjusts a variable frequency oscillator within the power transmitter, thereby changing the frequency of the sourced electrical power. The charging system further includes a phase detection circuit in communication with the controller and the off-transducer and configured to determine a phase difference between the alternating voltage and the alternating current supplied by the power source. The controller is configured to adjust the variable frequency oscillator based on the phase difference such that the frequency of the sourced electrical power maintains the phase difference within a desired range.

Wireless battery charging system varying magnetic field frequency to maintain a desired voltage-current phase relationship

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.
