scope:

The present document specifies technical characteristics and methods of measurements for wireless power transmission (WPT) systems using technologies other than radio frequency beam in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz, 6 765 - 6 795 kHz ranges. For the purpose of the present document WPT systems are classified into three different cases according to Table 1. Table 1: Distinction between WPT systems cases with regard to the communication technology WPT Cases (see note 3) RE-D article 3.2 RE-D article 3.1b EMC-D 1: only energy transmission, no data communication N/A N/A CENELEC EN 55011 [i.7] Group 2 (or more specific CENELEC standard if applicable), see note 1 2: energy transmission and data communication in frequency ranges covered by the present document ETSI EN 303 417 (the present document) ETSI EN 301 489-1 [i.8] ETSI EN 301 489-3 [i.9] N/A 3: energy transmission in frequency ranges covered by the present document and data communication in different frequency ranges Based on the communication function, this case is a "combined equipment" according to RED (see ETSI EG 203 367 [i.5]). Therefore, two options for homologation could be used: • Option 1: energy transmission frequencies (the present document), data communication frequencies: related ETSI standard • Option 2: energy transmission frequencies CENELEC EN 55011 [i.7] (see note 1 and note 2), data communication frequencies: related ETSI standard NOTE 1: WPT systems are expected to be included in future revision of CENELEC EN 55011 [i.7]. NOTE 2: CENELEC EN 55011 [i.7] are to be listed under the related articles in the OJEU for RE-D. NOTE 3: The division into these three cases could change once ITU has finalized their work on WPT-systems in response to Question ITU-R 210-3/1 and WRC 19 Agenda Item 9.1, Issue 9.1.6 [i.11]. The present document covers wireless power transfer systems according to cases 2 and 3 of Table 1, i.e. systems which consist of: 1) A power transmitter, with additional communication capability to control the charge function in conjunction with the receiving part. The power transmitter could also be named as charger. 2) A receiver, which supplies the received energy to a battery and performs a control/supervision function for the battery status and charge operation. Both parts in combination are able to transmit and receive data in addition to the power transfer mode e.g. to control the battery status and to optimize the transfer mode. These radio equipment types are capable of operating in the permitted frequency bands below 30 MHz as specified in Table 2. The present document covers fixed systems, mobile and portable systems. The limits and the frequency ranges of the present document are based on 2013/752/EU [i.2] and ERC/REC 70-03 [i.1]. For the clarification of open questions for high power wireless power transmission systems to charge vehicles a SRdoc ETSI TR 103 409 [i.4] was prepared. New specific requirements for such systems (e.g. higher H-field emission limits in the 79 - 90 kHz band) will be reflected within a future revision of the present document.
