Test Procedures E and H-field measurements should be made with the center of the probe at a distance of 20 cm surrounding the device and 20 cm above the top surface of the primary/client pair. These measurements should be repeated for three different client battery levels, 1%, 50%, and 99%. Record the test results. KDB 680106 D01 Wireless Power Transfer v04 (1) The power transfer frequency is below 1 MHz. (2) The output power from each transmitting element (e.g., coil) is less than or equal to 15 watts. (3) A client device providing the maximum permitted load is placed in physical contact with the transmitter(i.e., the surfaces of the transmitter and client device enclosures need to be in physical contact) (4) Only § 2.1091-Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions). (5) The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit, per KDB 447498, Table 1. These measurements shall be taken along the principal axes of the device, with one axis oriented along the direction of the estimated maximum field strength, and for three points per axis or until a 1/d (inverse distance from the emitter structure) field strength decay is observed. Symmetry considerations may be used for test reduction purposes. The device shall be operated in documented worst-case compliance scenarios (i.e., the ones that lead to the maximum field components), and while all the radiating structures (e.g., coils or antennas) that by design can simultaneously transmit are energized at their nominal maximum power. (6) For systems with more than one radiating structure, the conditions specified in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiating structures operating at maximum power at the same time, as per design conditions.

For instance, a device may use three RF coils powered at 5 W, or one coil powered at 15 W: in this case, both scenarios shall be tested. 4.1.3. Equipment Approval Considerations item 5 b) of KDB 680106 D01 Wireless Power Transfer v04 Requirement Device Yes. The operating frequencies are: 1. Power transfer frequency is less than 4 MHz. Watch: 320kHz Phone: 115kHz~205kHz TWS: 115kHz~205kHz Yes. The maximum output power is: 2.

The system may consist of more than one source primary coils, charging one or more clients. If more than one primary coil is present, Yes. The EUT has three source primary coils. the coil pairs may be powered on at the same time. 4. Client device is placed directly in contact with Yes. The client device is placed directly in the transmitter. contact with the transmitter. 5. Mobile exposure conditions only (portable exposure conditions are not covered by this Yes. Mobile exposure conditions only. exclusion). 6. The aggregate H-field strengths anywhere at or beyond 20 cm surrounding the device, and 20 cm away from the surface from all coils that by design can simultaneously transmit, and while Yes.
