WIRELESS POWER RECEIVER AND METHOD FOR USE IN A WIRELESS POWER RECEIVER

The disclosure herein relates relate to systems and methods for wireless power transfer between a wireless power outlet and a wireless power receiver. In particular the disclosure relate to a wireless power receiver enabled to monitor a sensor arrangement associated with the secondary coil of the power receiver and further determine its orientation relative to the wireless power outlet and calculate the electric power loss for an orientation. Furthermore, a monitoring unit associated with the wireless power receiver is operable to receive power transfer and orientation data from the sensor arrangement such as voltage, current, capacity, resistance, temperature and the like, to calculate efficiency data from the sensor data and further operable to communicate the efficiency data to a communication and control.
