Optimizing the magnetics and precise power technology are crucial for designing effective inductive wireless power transfer systems. Depending upon the technique, the amount of energy transferred can differ by a thousand times. Lower-power WPT systems […]
Using polyphase electromagnetic coupling coils with rotating magnetic fields to boost the power, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have demonstrated breakthrough performance for wireless charging of electric vehicles. A recent series of prototype demonstrations have established the effectiveness of the technology, which ORNL is seeking to license to manufacturers. More research is focused on developing even higher power levels suitable for larger vehicles, getting the system to mass production-level readiness and exploring more applications. […]
Now with a standard methodology set by SAE International for wireless inductive charging of electric vehicles, the technology is positioned to accelerate toward mainstream adoption – creating big wins for Mahle and Electreon who collaborated on the system chosen. The move also underscores further proliferation of magnetic technology in future automotive systems. Until now, formalizing universal standards for interoperable, safe, automated wireless charging has been seen as a major barrier on the path to scalable wireless EV charging deployments. […]
Researchers at Chalmers have developed an induction technology that enables battery charging without the help of a human or robotic arm. The technology is also so complete that it can soon be presented to industry. A new type of semiconductor based on silicon carbide. And a newly developed copper wire, as thin as a human hair. These are a couple of factors that suddenly made it more realistic to transmit high power through air. […]
Austrian substrate manufacturer AT&S is developing a new generation of miniaturized inductors that can be integrated into multi-layer printed circuit boards. They can enable the production of tiny voltage converters or ultra-thin wireless charging devices. […]
Linking new plating technology with its core competency in magnetic materials, TDK has developed a novel thin pattern coil that could revolutionize wireless charging of mobile devices. The new approach applies the magnetic material in […]
Wireless charging can be a tricky undertaking when you are dealing with autonomous mobile robots, but Seattle-based WiBotic is finding success with its system that combines both inductive and resonant magnetic technologies to accomplish the matchmaking. The […]
