Prospective customers for PowerbyProxi’s new integrated wireless charging smartphone solution can now evaluate demonstration units.
PowerbyProxi’s loosely-coupled wireless charging solution offers a number of key benefits over other approaches. It has designed a miniature receiver, efficient enough to be integrated into the processor board of a smartphone without causing over-heating, which works with a transmitter to provide complete spatial freedom of positioning on a sleek charging pad (see New Zealand Engineering News, February 2013, cover story). PowerbyProxi’s solution provides charging at the same speed as wired charging.
“We are confident that we have produced the most advanced wireless charging system available for smartphones,” says PowerbyProxi chairman Greg Cross.
“We believe that the key benefits of our approach –including spatial freedom and thermal management – are pre-requisites to the future development and wider adoption of wireless power for consumer electronics applications.”
PowerbyProxi’s wireless solution is the first system capable of being fully integrated into a smartphone. The receiver circuit and coil can fit inside a smartphone alongside other components with no modification to the device itself. No covers, sleeves or additional add-ons.
It is the only system available able to charge up to three devices simultaneously at full power, and the only wireless charging system that can charge devices at full-wired speed offering a charge time equivalent to wired chargers.
PowerbyProxi’s system ensures that advanced thermal management during charging. The main components of the device – the battery, back cover and LCD screen – do not overheat or damage the device when streaming video/music during charging.
The system has built-in foreign object detection – so coins, keys, silverware, and other metal objects do not overheat. It remains at room temperature while on the pad and while other devices are charging. PowerbyProxi meets all safety (RF exposure) requirements for safe operation of the device.
