Power Matters Alliance (PMA) was a global, not-for-profit, industry organization whose mission was to advance a suite of standards and protocols forwireless power transfer for mobile electronic devices (specifically a type ofinductive charging that competes with theQi standard). The organization was merged withAlliance for Wireless Power (A4WP) in 2015 to formAirFuel Alliance.
Founded byProcter & Gamble andPowermat Technologies in March 2012, PMA was networking technology companies in order to guarantee consumers interoperable devices which employed wireless power technology. Marked by the electron "P", PMAinterface standard described analog power transfer (inductive and resonant), digital transceiver communication, cloud based power management, and environmental sustainability. The PMA board of directors included representatives fromAT&T,Duracell,Starbucks, Powermat Technologies,Flextronics,Federal Communications Commission (FCC), andEnergy Star. The membership of the PMA was made up of companies across the mobile device ecosystem, including handset providers, service providers, chipset suppliers, manufacturers, test labs and public establishments.[2]
The PMA's stated mission was to formulate and advance a suite ofinterface standards for smart and energy-efficient transfer of wireless power. The PMA was actively publishing a suite of standards based oninductive coupling technology to provide advanced inductive and resonant power. In addition, the PMA sought to add a digital layer providing policy-setting, monitoring, and extensibleAPIs. The PMA managed interoperability, certification and logo programs according to these specifications.
On February 11, 2014, theAlliance for Wireless Power (A4WP) and the PMA announced that they signed an agreement calling for the following immediate next steps:[3]
This agreement was a move toward industry consolidation of wireless charging standards.[4][5]
In 2015 the organization was merged with The Alliance for Wireless Power (A4WP)[3] to form the AirFuel Alliance,[6] a global coalition of companies working together to bring next-generation wireless power technologies to market.
The 'Electron P' mark of interoperability was required to set compatibility standards across markets and industry, and across all links in the delivery chain of the alliance. It was used by industries and companies that adopt and implement the PMA standards. It was displayed at coffee shops, clubs, hair salons, airline terminals, entertainment venues, and on mobile phone accessories.
PMA conducted member conferences.
| Working Group | Description |
|---|---|
| IPG | The Inductive Power WG is a technical WG that is responsible for the development and maintenance of technical specifications for wireless power technologies based on direct electromagnetic induction. |
| SWG | The Sustainability WG is an advisory WG whose function is to advise the technical WGs with respect to the requirements that permit the wireless power technologies to fulfill the social, economic, and other requirements of present and future generations (e.g., energy saving, etc.). |
| RWG | The Regulatory WG is an advisory WG whose function is to advise the technical WGs with respect to the global emissions and coexistence requirements for the PMA technology being developed in support of the development of Wireless Power technologies which are compliant with regional regulatory requirements to the greatest extent possible. |
| CWG | The Certification WG is a technical WG that is responsible for the establishment of world class certification program with short, medium and long term programs including the development and maintenance of test plans and implementation conformance specifications. |
| MPG | The Multimode Power Group (MPG) is a technical WG that is responsible for the development and maintenance of technical specifications for multimode operations between the PMA inductive technologies and other PMA endorsed wireless power transfer technologies. |
| NWG | The Network Working Group (NWG) is a technical committee responsible for the development and maintenance of network communication strategies and protocols for network related functionality of wireless charging spots. The scope of work done in this committee relates to provisioning, operation, administration, management, and user interaction of the network. The work ensures a viable framework to ensure continued growth of the wireless charging ecosystem. |
| TSC | The TSC is the overall approval and coordinating body for all PMA technical activities conducted in one or more of the technical PMA WGs. The TSC includes appointed leadership, WG Chairs, and Program Office staff. |
| UPG | UPG is chartered with the leadership and development of standardized specifications for wireless power transfer based on non-magnetic technologies such as RF, ultrasound and laser that deliver power at a distance of up to 10m (30 feet). |
On June 11, 2014,Starbucks announced plans to provide wireless chargers at its coffeehouses in the United States and to test the wireless chargers in select European and Asian markets.[7][8]
