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.

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 close coupled inductive
  applications (resonant and non-resonant).

Next Steps / Actions

• The outcome of the Rapporteur group is expected
  to be presented to the next TC ERM meeting (45)
  on 21-24 November 2011.
