Wireless charging system for charging vehicular battery
First Claim
1. A wireless charging system for charging a battery in a vehicle, the vehicle includes a receiving coil positioned on an underside of the vehicle, the wireless charging system comprising:
- a coil charge device including a transmitting coil and a carriage, wherein the transmitting coil is positioned on the carriage;
a linear track extending across a designated path, wherein the coil charge device is positioned on and moveable along the linear track;
a linear motor operable to move the coil charge device along the linear track; and
a charge control module configured to control a position of the coil charge device along the designated path via the linear motor and operate the transmitting coil during a charge operation to charge the battery of the vehicle;
wherein the charge control module is configured to control the linear motor to position the coil charge device relative to the receiving coil such that an induced voltage across the receiving coil is at a maximum indicating that the charge coil device is aligned with the receiving coil.

8. A wireless charging system for charging a battery in a vehicle, the vehicle includes a receiving coil positioned on an underside of the vehicle, the wireless charging system comprising:
-
a coil charge device including a transmitting coil and a carriage, wherein the transmitting coil is positioned on the carriage; a linear track extending across a designated path, wherein the designated path extends across one or more parking spaces, and the coil charge device is positioned on and moveable along the linear track; a linear motor operable to move the coil charge device along the linear track; and a controller configured to wirelessly communicate with one or more vehicles parked at the one or more parking spaces, control a position of the coil charge device along the designated path via the linear motor based on a position of a designated vehicle, and operate the transmitting coil during a charge operation to charge the battery of the designated vehicle, wherein the designated vehicle is one of the one or more vehicles parked at the one or more parking spaces and is in communication with the controller, and during the charge operation, the controller positions the coil charge device under the designated vehicle and supplies power to the transmitting coil to induce an induced voltage in a receiving coil of the designated vehicle; wherein the charge control module is configured to control the linear motor to position the coil charge device relative to the receiving coil such that the induced voltage across the receiving coil is at a maximum indicating that the charge coil device is aligned with the receiving coil. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
