Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a wireless power transmission apparatus that supports charging of one or more wireless power receiving apparatuses. The wireless power transmission apparatus may include multiple primary coils organized in groups (referred to as zones). Each zone may have a local controller for managing operation of one primary coil in the zone at a time. A master controller may selectively couple the primary coils to the local controllers. When a first primary coil is coupled to the local controller for a zone, the other primary coils in that zone may be disabled. The master controller may manage which primary coils from neighboring zones are coupled to their respective local controllers. Thus, when the first primary coil is activated, the adjacent primary coils (near the first primary coil) can be muted or disabled to mitigate undesirable interference.

CPC classification number: H02J50/80 , H02J50/10 , H02J50/60 , H04L25/4902
Abstract: This disclosure provides systems, methods and apparatuses for a new communication technique between a wireless power transmission apparatus and a wireless power reception apparatus. The new communication technique may be more efficient for communication of a feedback parameter or other control information compared to a legacy packet-based digital communication technique. The new communication technique may use a pulse width modulation (PWM) signal as an analog representation of a feedback parameter or other control information. In some implementations, the PWM communication technique in this disclosure can be used for a variety of control or feedback information from the wireless power reception apparatus to the wireless power transmission apparatus. Furthermore, in some implementations, the PWM communication technique may be used for feedforward information from the wireless power transmission apparatus to the wireless power reception apparatus.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless power reception. Various implementations relate generally to a wireless power reception apparatus including multiple secondary coils that receive wireless power from corresponding primary coils of a wireless power transmission apparatus. When a secondary coil receives power form a primary coil, they form a latched coil pair. Initially, the wireless power reception apparatus receives via a number of latched coil pairs. Coil pairs may de-latch as they physically move out of alignment. If one or more coil pairs de-latch, voltage may drop in the latched coil pairs. The wireless power reception apparatus includes a power controller that can detect drops in voltage resulting from de-latching coil pairs. In response, the power controller can modify current drawn from the remaining latched coil pairs. By modifying current drawn from the remaining latched coil pairs, the power controller can avoid system failure.
