  1. Wireless Chargers Gabrielle Owen ETSI TC ERM Chair

  2. European Regulatory Issues TCAM is the Telecommunications Conformity Assessment and Market Surveillance Committee of the European Commission (DG Enterprise). • Interpretation and guidance on the European telecommunications equipment compliance procedures fall under the remit of the TCAM. • In TCAM there is a discussion about whether wireless chargers should either fall under the scope of the RTTE Directive (as radio communication devices) or the EMC and Safety Directives. • TCAM has requested a view from ETSI and this issue and their questions are at the core of a work item in TC ERM.

  3. Observations • The TC ERM Rapporteur group has observed and is considering that there is : • a wide range of wireless power transfer (WPT) technology proposals and a wide range of transfer powers. • no defined frequency range of operation. • a range of charging system architectures with respect to the power transfer function and control and feedback. • an interpretation by some that sensing and control feedback is considered as radio-communication. • ongoing industry standards activity for evolving WPT technologies. Consideration in the ERM work has been limited to wireless charger devices employing inductive coupling techniques currently or soon to be available on the European market.

  4. Next Steps / Actions The outcome of the Rapporteur group is expected to be presented to the next TC ERM meeting (#45) on 21-25 November 2011.
