INTERCONNECTED WIRELESS BATTERY CHARGING AND REGENERATIVE BRAKING SYSTEMS FOR AN ELECTRIC VEHICLE
First Claim
1. A wireless battery charging system, comprising:
- an off-vehicle transducer electrically 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;
a frequency converting circuit disposed within a vehicle and electrically connected to the on-vehicle transducer, wherein 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;
a battery disposed within the vehicle; and
a regenerative braking circuit disposed within the vehicle and electrically connected to the frequency converting circuit and the battery, wherein 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.

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.
