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 Page: 4 (21) Parts device under test consists of: T251-0030/23 Page: 5 (21) 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 Page: 6 (21) 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. Actual photo of the parts in combination with marked exposure measurement sides Left side of WPP Above WPP Right side of WPP Back of WSU Back of WPP Below WPP T251-0030/23 Page: 7 (21) Radiofrequency radiation exposure according 47 CFR 1.1307 clause (b)(1)(i)(B): With respect to the limits on human exposure to RF provided in § 1.1310 of this chapter, applicants to the Commission for the grant or modification of construction permits, licenses or renewals thereof, temporary authorities, equipment authorizations, or any other authorizations for radiofrequency sources must prepare an evaluation of the human exposure to RF radiation pursuant to § 1.1310 and include in the application a statement confirming compliance with the limits in § 1.1310. 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. 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.

PPL Specification Specifications are listed below: Number Content PPL0000 Carrier frequency shall be 13,56 MHz (13,553 ...13,567 according to ETSI EN 300 330) PPL0010 Physical layer uses 2-PSK encoding. PPL0020 Communication mode shall be half-duplex. PPL0030 Secondary side initiates data exchange to start, perform and end a charging cycle. Secondary Transmit Frame is called Communication Request. Secondary side is MASTER PPL0040 Primary side answers data exchange to start, perform and end a charging cycle. Primary Transmit Frame is called Communication Answer. Primary side is SLAVE OPTIONAL Initiation of data exchange possible from primary side. PPL0050 A loop of communication request and answer shall take less or equal 16.66 ms. PPL0060 During each loop, at least 24 bytes of Data shall be transferred in total. Either From master to Slave or From slave to Master. For Example. 12 from Slave to Master and 12 from Master to slave. PPL0070 Communication shall be robust against WPT frequency and noise caused by the WPB Inverter switching. 1 out of 60 loops may be corrupted. / (1 Fail per Second).
