Wireless charging moves a step closer

The Wireless Power Consortium has delivered the first part of its technical specification to members.

The publication of the system interface definition will enable Consortium members to start developing products that work with the emerging Qi standard.

Part one of the interoperability specification defines the interface between wireless charging stations and power receivers. The Consortium is also finalising the performance requirements and compliance test specifications, so that product developers know what they need to do to get products certified so they can carry the Qi logo (shown above).

“This first part of Qi’s v 1.0 specifications sets the clock running on the introduction of consumer products that cut the last cord for true simplicity in wireless lifestyle,” said Camille Tang, chair of the promotion work group of the Wireless Power Consortium.

“The standard provides confidence to consumers that their Qi-enabled electronic devices will be compatible with any Qi-branded charging device, regardless of manufacturer. For manufacturers, Qi offers a versatile range of receivers and transmitters, providing flexibility in design options as they plan their product roadmaps.”

The Wireless Power Consortium was established at the end of 2008. Membership includes Atmel, Duracell, Energizer, Fulton Innovation, Hosiden, LG Electronics, National Semiconductor, Nokia, Olympus, Philips, Rohm, Samsung Electronics, Sanyo, Sony Ericsson Mobile Communications, ST-Ericsson, Texas Instruments, Toko, Verizon Wireless, and others. The membership has doubled in the past three months, to more than 40 companies.
