A press release I just received might just be the big news coming out of the forthcoming CES in Las Vegas. Charging mobile devices without power cords has long been a dream for many of us and Fulton Innovation, a company backed by Motorola (among others) plans to announce the eCoupled Intelligent Wireless Power technology. It’s very scientific in principle but the bottom line is devices can be produced that draw power through proximity to the source rather than be plugged in like it’s done today.
How eCoupled Intelligent Wireless Power Works
eCoupled technology leverages inductive coupling, which works by transferring energy from one device to another through a shared magnetic field. The technology stems from the foundational work of renowned scientists Michael Faraday and Nikola Tesla.
Fulton Innovation’s intelligent inductive power technology overcomes historic limitations of inductive coupling by using resonance-seeking circuitry that dynamically seeks and optimizes power transfer under multiple, varying load conditions and spatial configurations.
Conventional inductive coupling typically requires careful "tuning" of the power supply circuit with the device being powered. Only minor variations in the physical positioning and power requirements of the inductively powered are tolerated. Any variation in either the load or the positioning of the power supply relative to the device can severely impact performance.
eCoupled technology addresses the limitations of spatial rigidity, static loads and unacceptable power losses. The eCoupled technology power supplies adapt to multiple loads and spatial configurations while maximizing energy transfer efficiencies by dynamically seeking resonance between the power supply and device at high frequencies to achieve the optimal coupling coefficient under all conditions. Energy efficiency is increased over conventional inductive coupling with power losses as low as 2 percent, making eCoupled technology comparable to hardwired connections.
eCoupled technology includes an intelligent feedback and control system, communicating with individual devices in real time, which allows the technology to determine not only power needs, but also factors such as age of a battery or device and charging lifecycles on an individual basis in order to supply the optimal amount of power to keep a device at peak efficiency.
Kevin and I will try to track these folks down at the CES in a couple of weeks and we’ll be sure to pass along what we uncover.
