Abstract
A wireless vehicle battery charging system. The wireless vehicle battery charging system includes a supply pad having a control circuit electrically connected to a power source. A receiver pad is mounted to an underside of a vehicle and electrically connected to a vehicle battery. The receiver pad and supply pad each include sensors. The supply pad sensor is configured detect the presence of the receiver pad sensor when it is positioned above the supply pad sensor. The control circuit is configured to wirelessly transmit power to the receiver pad via resonant inductive coupling between the supply pad and receiver pad when the supply pad sensor detects the receiver pad sensor. The receiver pad is configured to charge the vehicle battery via the power received from the supply pad.
