scope:
The present document provides information of existing and future wireless power transmission (WPT) systems using technologies other than radio frequency beam, operating in the frequency range below 30 MHz and complements the published ETSI TR 103 409 [i.20], which contains information about WPT systems for electrical vehicles (WPT-EV) in the frequency range 79 - 90 kHz.
The related harmonised standard for WPT systems is ETSI EN 303 417 [i.11] and it currently applies to WPT technologies other than radio frequency beam, in the frequency ranges 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz and 6 765 - 6 795 kHz.
During the development of ETSI EN 303 417 [i.11], concerns were raised whether the frequency allocations for inductive SRDs according to EC Decision 2013/752/EU [i.3] and the ERC/REC 70-03 [i.2], annex 9 are applicable for WPT systems.
Therefore the present document aims to request CEPT to clarify whether the WPT systems using the inductive frequency range below 30 MHz could be seen as "inductive SRDs" and could use the frequency allocations from Decision 2013/752/EU [i.3] and the ERC/REC 70-03 [i.2], annex 9.
The present document deals only with WPT based on technologies other than radio frequency beam (e.g. magnetic induction).
It reviews the present regulations for inductive WPT systems, the related markets and the evolution of the technology, and it identifies requirements to amend the limits for WPT systems operating below 30 MHz.
The present document contains the necessary information to support the possible co-existence and compatibility studies to be conducted by the CEPT/ECC, including:
• market information;
• technical information;
• regulatory issues.
