Wireless transmission test

System efficiency:
The ratio of output power to input power is the actual efficiency of wireless charging.

1. Test method: Connect to a DC power supply, adjust the input voltage to 5.1V, connect the output of the receiver to a load meter, and adjust the load meter to output in a constant current mode, increasing the output in steps of 100mA until 1A.

2. Notes: The wiring from the DC power supply to the product input terminal should be kept as short and thick as possible to minimize DC losses; similarly, the wiring from the output terminal to the load meter should also be kept as short and thick as possible. The effective distance between the transmitting and receiving ends should be maintained at around 2‐4mm for optimal testing results.

3. Efficiency Test:
   The results are as follows:

Dynamic Energy Balance Testing For Mobile Phones：

Metal foreign object detection (FOD)：
Testing Description:

1. Turn on the transmitter TX. Place a metal foreign object on the TX. If the foreign object extends beyond the coil range of the TX, the TX should not transmit power; otherwise, the test is considered a failure.
2. Turn on the transmitter TX. Place a metallic foreign object on the TX within the coil range of the TX. Then, place the receiver RX on the foreign object. The TX should not transmit power in this scenario; otherwise, the test is considered a failure.
   Phones undergoing testing| Metal foreign object| Test result
   ---|---|---
   iPhone XR| 1 round coin| OK
   Samsung S8+| 1 round coin| OK
   HUAWEI MATE30| 1 round coin| OK
   Xiaomi 9| 1 round coin| OK
   HUAWEI V10| metal shell| OK
   HONOR V20| metal shell| OK
