  1. TTA WPT activities &Proposal of revised resolution Dr. Hyeonwoo, LEE Chairman of TTA PG709, TTA

  2. Highlight of Current Activities(1/2) • TTA Wireless Power Transmission/Transfer (WPT) PGs developed 10 domestic Standards/Reports such as WPT use case & service scenario, definition of efficiency, evaluation method, in-band resonant WPT system and management for WPT • Followings are work areas within TTA • - WPT applications and services of ICT appliances' equipment standardization • - WPT of IT appliances' vehicles and mobile device standardization • - WPT technologies and measurements standardization to operate chips or cells • - Affects on human body Source : ISO 17465

  3. Highlight of Current Activities(2/2) • TTA PGs actively participate in related international standardization activities such as APT AWG, CJK and GSC for the collaboration and interoperability on WPT • Particularly, in this year TTA PGs will review De-facto Technical specifications from WPC, A4WP, etc. for adoption as TTA Standards. • Also, TTA PGs will review the TTA Standard on ‘Management Interface for WPTMulti-devices (TTAC.KO-06.0304) (see Supplementary Slides)’ accommodating multiple power source from different technologies method for example resonance and inductive WPT. Source : ISO 17465

  4. Strategic Direction • Interoperability among the WPT products in same application should be achieved by standardization effort to the maximum extent possible. • Sharing related information and collaborating among GSC members are important to encourage technology development as well as global harmonization. • GSC needs to offer opportunities to its members to discuss related issues including standard deveopment activities

  5. Challenges • Product Diversification • - As market is increasing, each Alliances make the WPT Technical • Specifications which has different structure & protocol • Frequency/Regulation Issues • - International standards and harmonized radio frequency, EMI/EMC, and • SAR (Specific Absorption Rate) regulations are necessary for its effective • global solution deployment • - It is reported that magnetic resonant WPT products for portable device and • CE devices using lower WPT power are expected to come out in the market • in 2014 in some countries, which may utilize the current radio regulations • intended for the existing products. • - For WPT for Electronic Vehicle and high-power applications, the earliest • deployment is expected in 2015 as new regulatory discussions are • necessary to introduce

  6. Next Steps / Actions • Sharing information in the CJK and other SDOs is important to achieve regional and global harmonization in WPT technology standardization and regulation. • It is time to prepare further development of global harmonization in technology and regulation to achieve maximum interoperability. • It is proposed to set up Task Force (TF) for developing GSC Report on WPT based on CJK WPT TR 1 including other SDO’s information and further global direction before GSC-18.

  7. Proposed Resolution • It is proposed to modify Resolution GSC-16/34 taking into account current status that have occurred in the WPT standardization area • - to change the title of WCS into WPT considering • ITU and ISO’s terms • - to work together through GSC TF and report to GSC-18 • Attachment: Proposed Modification of Res. GSC-16/34

  9. The List of TTA Standards/Reports

  10. Management Interface for WPT Multi-devices (TTAC.KO-06.0304) • Overview • MWPMS(Multi-device Wireless Power Management System) is used to efficiently transfer wireless power to multiple power receivers. • MWPMS consists of an MWPC (Multi-device Wireless Power Charger) and one or more of MWPRs (Multi-device Wireless Power Receivers).

  11. TTA PGs on WPT Chart • TTA PG709 work scope is based on cellular/low-power WPT • TTA PG309 work scope is related to EMI/EMC including WPT • TTA PG422 work scope is based on high-power, specially electric vehicle. •  For avoiding duplication work among 3 groups, TTA wireless Power transmission PCG was established and now discussing how to reform and merge PGs.

  12. TTA PG709 Overview (1/2) • Established in Mar. 2011 • Work Scope • Standardization on wireless charging of mobile ICT terminals by battery-operated [mobile phone (5W), Tablet PC (30W), Laptop (120W)] • Published Standards and Technical Reports • Use case for wireless power transfer • Requirements for wireless power transfer • Service scenario for Wireless power transfer • Definition on efficiency of wireless power transfer for mobile devices • Evaluation Methodology • Interface definition for highly resonant wireless power transfer • Control protocol of wireless power transfer

  13. TTA PG709 Overview (2/2) • New Work Item • Loosely-coupled WPT and management protocol • Activities for international standardization • ISO/IEC JTC1 SG6, ISO/IEC TC100, CJK WPTSIG, etc • 3 Working Groups, 15 members TTA PG709 Steering Committee WG 2 WG 1 WG 3 • Service & Structure • Evaluation • Interface

  14. TTA PG309 Overview • Established in Mar. 2004 • Work Scope • Standardization on electromagnetic waves, human protection from EW (EMI/EMC etc.) • Standardization on maritime communication • Standardization on the radio properties of equipments for radio application (e.g. WPT etc.) and EMC etc. • Work Item • EMI Measurement methods for wireless charging electric vehicle

  15. TTA PG422 Overview (1/2) • Established in Feb. 2012 • Work Scope • Standardization of wireless power transmission application and service for non-battery powered IT appliances • Standardization of wireless power transmission for vehicles • Standardization of wireless power transmission technologies and measurement methodologies for chip or element-driven devices • Published Standards • Guideline for functional receiver components of wireless power transfer system via coupled magnetic resonances • System Control Sequence of Resonant Wireless Power Transmission

  16. TTA PG422 Overview (2/2) • Work Items • Measurement methodology to estimate the efficiency of wireless energy transmission: part 1 : superpower medium speed radio application equipment • Communication protocol for wireless power supply of wireless charging on moving electric vehicle • Efficiency measurement method of high power wireless power transfer : part 1 moving(medium speed) electric vehicle • Efficiency measurement method of high power wireless power transfer : part 2 moving(low speed) electric vehicle • Evaluation Method of Ultrasonic Receiver Efficiency for Wireless Power Transmission • Multi-resonant power consumption wireless power transmission system management • Common Transceiver coil using for magnetic induction type and magnetic coupled resonance type
