Abstract

A testing system for wireless power transfer systems, including a stationary plate, a rotating plate, and a driver to rotate the rotating plate with respect to the stationary plate.

Claims

1. A test system, comprising:

a stationary plate,

a rotating plate, and

a driver that rotates the rotating plate with respect to the stationary plate.

2. The test system of claim 1, wherein the rotating plate and stationary plate are intermittently in proximity to simulate the conditions of in-motion wireless power transfer.

3. The test system of claim 1, wherein the rotating plate and stationary plate are configured so that a wireless power transfer receiver or transmitter may be mounted thereto.

4. The test system of claim 1, wherein the rotating plate passes directly over the stationary plate when the driver rotates the rotating plate.

5. The test system of claim 4, wherein the distance between the stationary plate and rotating plate when they align is 6 to 20 inches.

6. The test system of claim 1, further comprising a support arm that attaches the driver to the rotating plate.

7. The test system of claim 1, wherein the driver variably rotates the rotating plate in a range of from 0-150 rpm.

8. The test system of claim 6, wherein the support arm has an adjustable length.

9. The test system of claim 1, wherein the driver is powered by wireless power transfer.

10. The test system of claim 1, wherein the stationary plate has a wireless power transfer receiver mounted thereto and the rotating plate has a wireless power transfer transmitter mounted thereto.

11. The test system of claim 1, wherein the stationary plate has a wireless power transfer transmitter mounted thereto and the rotating plate has a wireless power transfer receiver mounted thereto.
