Abstract

An apparatus for multi-pad wireless charging is disclosed. The apparatus includes a plurality of primary pad apparatuses 102. Each primary pad apparatus 102 is positioned to transmit power to a secondary pad apparatus of a vehicle. The primary transmitter pad apparatuses 102 are spaced apart sufficient for each of a plurality of vehicles to be positioned over one primary pad apparatus 102a1 of theplurality of primary pad apparatuses 102. The apparatus includes a power converter apparatus 104 connected to each of the plurality of primary pad apparatuses 102, a power feed 106 that provides power to the power converter apparatus 104 and a sharing controller 108 that selectively controls which of the plurality of primary pad apparatuses 102 transmits power to a secondary pad apparatus and / orcontrols power sharing between the primary pad apparatuses 102.

Description

technical field [0001] The present invention relates to wireless power transfer, and more particularly to wireless power transfer to multiple charging pads fed from a single source using wireless. Background technique [0002] Wireless Power Transfer ("WPT") is an emerging technology that is being used more frequently in many situations. One use of wireless power transfer is for electric vehicles. Electric vehicles can be expected to reduce noise and pollution. However, plug-in electric vehicles are cumbersome, inconvenient, and have mechanical parts that can wear out. [0003] Some electric vehicles such as buses, forklifts, trucks, etc. are in fleets where they can be charged at a central facility or at a location where multiple vehicles can be charged at one time. Typically, the charging facility is utility fed, or may have a secondary power source, such as a solar power source. Other charging facilities may have self-generated power from wind turbines, solar panels, ...
