It consists of Primary Box (EOE18010815) that gets power from the grid and of Primary Pad (EOE18010851) that transfers the energy. Energy is transferred in the frequency range 55 – 65 kHz. Communication between primary and secondary pad is at 13,56 MHz. T251-0030/23 M2 Page: 4 (36) Parts device under test consists of: T251-0030/23 M2 Page: 5 (36) The WCS allows the user to charge the battery of industrial vehicle wirelessly by means of a magnetic field between WPP and WSU. The magnetic field which is generated and transmitted by the WPP is received by the WSU, and then converted to direct current for charging the battery. The WCS is capable of outputting up to 30 kW for battery charging. The magnetic field generated during the charging process can cause metal and other foreign objects to become hot. Therefore, it is important to keep the charging area free of foreign objects. The magnetic field is only emitted by the WPP when there is a WSU in the charging area. T251-0030/23 M2 Page: 6 (36) 2 ASSESSMENT PROCEDURE RF EXPOSURE REQUIREMENTS according 680106 D01 RF Exposure Wireless Charging App v03r01 RF exposure must be evaluated with the client device(s) being charged by the primary at maximum output power. The RF exposure requirements must be determined in conjunction with the device operating characteristics, according to the mobile and portable exposure requirements in Sections 2.1091 and 2.1093 of the rules. RF exposure compliance is determined with respect to Sections 1.1307 (c) and (d) of the FCC rules. Evaluation is based on following conditions: field strengths do not exceed the following reference levels: - 83 V/m for the electric field and - 90 A/m for the magnetic field. Sample has been turned on with maximum power transferred between pads. While working, communication was active. Measurement distances were set as in table below under clause 3 of this report. Marking of positions is as per below pictures.

Limits: Measurement was done on WPP and WSU separately to show radiation exposure of both devices. Both were programmed to continuously work in communication mode only. Power transfer function has been disabled for this measurements, only 13.56 MHz communication was working and evaluated. Sample has been turned on with maximum power transferred between pads.

The secondary pad was set to declared distance to the primary pad. T251-0660/22 Page: 5 (34) 1.2 Antenna requirements (§15.203) Requirement An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of §15.211, §15.213, §15.217, §15.219, or §15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with §15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. Conclusion: PASS; EUT has internal PCB antenna.
