Vehicle Installed Wireless Charging System Page 4 of 6 Summary of Results 1.5 The procedure used to determine the RF power density for the mobile condition was based upon E-field and H-
field measurements recorded using a calibrated probe. All measurements were recorded with the EUT (the charging system) transferring power to the Rx dummy loads that support the WPC charging protocols. The pad itself was running off of a 9VDC power supply. Care was exercised to ensure that the charging system was transferring power to the dummy loads throughout the duration of the field strength measurements. During testing, the charging system with WPC dummy load was placed on a non-conductive (composite plastic) table top. The probe was positioned at the location where there is maximum field strength on each side of the EUT. The maximum E-field and H-field is reported below. Distance (cm) A
