VEHICLE CHARGING PAD HAVING REDUCED THICKNESS

摘要

This disclosure provides systems, methods and apparatus for charging pads for use with wireless power systems. In one aspect a vehicle charging pad having a reduced thickness is provided. A charging pad may include multiple wire coils and a ferrite block backing. By forming a longitudinally extending slot in the ferrite block, a portion of the wires extending from the coils can be routed through the slot in the ferrite block to decrease the overall thickness of the charging pad.

主权项

1. A charging pad, comprising:
a first coil structure, the first coil structure including:
a first coil section wound in a first direction; anda second coil section coplanar with the first coil section and wound in a second direction opposite the first direction; a second coil structure; and a ferrite block structure, the ferrite block structure including two ferrite block sections separated by a longitudinally extending slot, and at least one wire extending from the first coil structure and at least one wire extending from the second coil structure extending through a portion of the longitudinally extending slot in the ferrite block structure.
