Systems, methods and apparatus for wireless charging are disclosed. A test apparatus has a receiving head configured to provide a measurement signal representative of electromagnetic flux received from one or more transmitting coils of a wireless charging surface, a numerically-controlled stage configured to position the receiving head at a selected point in three-dimensional space above wireless charging surface, and a processor configured to cause the numerically-controlled stage to position the receiving head at the selected point in three-dimensional space, and use the measurement signal to determine magnitude of the electromagnetic flux or power received from the wireless charging surface proximate to the selected point in three-dimensional space.

Multi-coil wireless charger validation

A charging device has a first printed circuit board (PCB) having a top metal layer and a bottom metal layer, where a first plurality of charging cells is provided on the top metal layer of the first PCB and a second plurality of charging cells is provided on the bottom metal layer of the first PCB. The charging device may have a second PCB having a top metal layer and a bottom metal layer, where a third plurality of charging cells is provided on the top metal layer of the second PCB and a fourth plurality of charging cells is provided on the bottom metal layer of the second PCB. An adhesive layer may join the first and second PCBs. One or more interconnects may be provided between the bottom metal layer of the first PCB and the top metal layer of the second PCB.
