Abstract

This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect, an apparatus is provided that includes a first conductive structure configured to wirelessly receive power via a magnetic field generated by a transmitter conductive structure having a length greater than a width. The first conductive structure has a length greater than a width and includes co-planar loops enclosing first and second areas. The first conductive structure has first and second edges each intersecting a first geometric line running along the length of the first conductive structure. The apparatus includes a second conductive structure configured to wirelessly receive power via the magnetic field. The second conductive has a length greater than a width. The first geometric line runs along the length of the second conductive structure. The first geometric line is substantially perpendicular to a second geometric line running along the length of the transmitter conductive structure.

Description

technical field [0001] The present disclosure relates generally to wireless power transfer, and more particularly, to devices, systems, and methods related to wireless power transfer to remote systems, such as vehicles including batteries. More specifically, the present invention relates to coil arrangements for induction coils in wireless power transfer systems. Background technique [0002] Remote systems, such as vehicles, that incorporate electrically derived motion power received from an energy storage device, such as a battery, have been introduced. For example, hybrid electric vehicles include an on-board charger that charges the vehicle using power from the vehicle's brakes and a conventional motor. Purely electric vehicles typically receive electricity from other sources to charge their batteries. Battery electric vehicles (EVs) are generally proposed to be charged by some type of wired alternating current (AC), such as a household or commercial AC supply. A wire...
