MULTI-COIL WIRELESS CHARGER VALIDATION

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.
