A non-contact power transmission device includes a resonant circuit, which includes a switching element and a primary coil electrically connected to the switching elements. The resonant circuit induces an alternating power with the primary coil in accordance with the resistance value of the resonant circuit by switching the switching element. A secondary coil receives, from the primary coil in a non-contact manner, the alternating power at a position intersecting an alternating magnetic flux occurring at the primary coil. A primary side controller ON/OFF controls the switching element and changes, based on information to be conveyed to the secondary coil, the resistance value of the resonant circuit, thereby modulating the amplitude of the alternating power induced in the primary coil. A secondary side controller demodulates, from the change in the amplitude of the alternating power received by the secondary coil, the information conveyed to the secondary coil.

An electrical charging system (ECS) to electrically charge a battery includes a power transmitter, an energy coupling arrangement, at least one electrical signal shaping device (ESSD) including a controller, and an alignment means. The arrangement includes a first transducer disposed external to the vehicle and a second transducer attached with the vehicle. The alignment means communicates with the vehicle to ensure repeatable vehicle positioning so that the second transducer is positioned relative to the first transducer so that the second transducer receives the energy produced by the power transmitter wirelessly transmitted from the first transducer. The energy received by the second transducer is electrically shaped by the ESSD and further electrically transmitted through the ESSD as controlled by the controller to electrically charge the ESD. Methods to operate and electrically transmit energy through the ECS to electrically charge the EDS are also presented.
