Abstract

The disclosure relates to a method for wireless transmission of a power between a transmitter and a receiver, comprising a power phase and a measurement phase, wherein the receiver measures a received power during the measurement phase and transmits information on the measured power to the transmitter, wherein the transmitter compares the power transmitted therefrom to the power measured by the receiver and identifies a power loss therefrom, wherein the power phase does not occur if the power loss exceeds a maximum allowable threshold, wherein the transmitter transmits a power during the measurement phase which is smaller than the power transmitted during the power phase.

Claims

1. A method for wireless transmission of a power between a transmitter and a receiver, comprising a power phase and a measurement phase, wherein the receiver measures a received power during the measurement phase and transmits information on the measured power to the transmitter, wherein the transmitter compares the power transmitted therefrom to the power measured by the receiver and identifies a power loss therefrom, wherein the power phase does not occur if the power loss exceeds a maximum allowable threshold, wherein the transmitter outputs a power during the measurement phase which is lower than the power output during the power phase, wherein the power during the measurement phase is chosen such that the power loss is accurately measured down to 250 mW.

2. The method according to claim 1, wherein the measurement phases and power phases alternate in a succession of time.

3. The method according to claim 1, wherein the measurement phases are performed at regular time intervals.

4. The method according to claim 1, wherein prior to a power-phase, a one-time measurement phase is performed.

5. The method according to claim 1, wherein during a power phase, the transmitter outputs a power of more than 5 W, particularly 15 W.

6. The method according to claim 1, wherein during a measurement phase, the transmitter outputs a power of 5 W at maximum.

7. The method according to claim 1, wherein the transmitter initiates a measurement phase.

8. The method according to claim 1, wherein the receiver initiates a measurement phase.

9. The method according to claim 2, wherein the measurement phases are performed at regular time intervals.
